Jumping the String | New Research to Improve Bow Hunting Success (#462) @GrowingDeer.tv


GRANT: The entire GrowingDeer Team has been
hitting the woods trying to put some fresh venison in the freezer. GRANT: Pro Staffer Chase White and his son,
Rylan, have been hunting also. GRANT: Rylan has shot several deer over the
years. GRANT: This year, Rylan wanted to try to take
a deer with his crossbow during archery season. Recently, Chase and Rylan headed to a field
where lots of deer have been feeding; got settled in and, yeah, they saw a lot of deer. GRANT: One of ‘em was a nice buck. GRANT: The buck never made it within Rylan’s
range, but a little bit later, a doe stepped out at 30 yards. RYLAN: (Whispering) (Inaudible) CHASE: (Whispering) Yeah, but the second – in
between the second and third one. Make sure you aim a little bit low because
she’s gonna drop. Okay? Whenever you’re ready. Wait. She’s quartering away now. GRANT: The doe seemed calm; had her head down
feeding… CHASE: (Whispering) There she is. GRANT: …so Rylan took the shot. GRANT: Unfortunately, it was a miss. Hey, that’s happened to all of us. But the miss didn’t deter Rylan. RYLAN: (Whispering) (Inaudible) GRANT: The next day, Chase decided to change
his setup. He noticed there was an oak out in the middle
of the field that was dropping lots of acorns and deer were feeding in that area. So, he put a couple Summits in the oak hoping
for another shot. CHASE: We came in this morning; we’ve made
a new set right here in the tree in the middle of the food plot. It’s risky, but we’ve got a great wind
for tonight. This may be the only night we get to sit it,
but we’ve got a good northeast wind and the deer have been going between this tree
and the property line which is about 40 yards in front of me. If they keep doing what they’ve done the
last two times we’ve sit here, we should have a good opportunity. GRANT: That afternoon, Chase and Rylan headed
to the oak and got set up. GRANT: It seemed like a good plan and deer
were coming their way. GRANT: A doe worked her way under the tree
but didn’t offer Rylan a shot. GRANT: Finally, she drifted out from under
the limbs and Rylan had an opportunity. GRANT: Based on the shot placement, Chase
and Rylan wisely decided to wait a few hours before taking up the trail. CHASE: What do you think about that? Good job, brother. Proud of you. Love you. RYLAN: Love you, too. Thanks for taking the time to (Inaudible). CHASE: Yeah. (Inaudible) GRANT: Great job, Rylan. Good strategy and you put fresh venison in
the freezer for your family. I’m proud of you. GRANT: There are several easy lessons from
Chase and Rylan’s hunt. First, they used MRI – most recent information. They set at the edge of the field, noticed
the pattern, changed – and the next day, it paid off. GRANT: Second – during Rylan’s first hunt,
when you play it in real time, it seems it was just a miss. But when you slow it down frame by frame,
you see that the doe actually dropped several inches and rolled away from the sound of the
bow. GRANT: Reviewing Rylan’s shot at that first
doe, well, it tells me this is the perfect time to share with y’all some research we
did this summer. ANNOUNCER: GrowingDeer is brought to you by

at the shot of a bow, will drop and get out of Dallas before the arrow gets there. Those observations caused me to ask a lot
of questions and do some research this summer on what’s happening when a deer ducks before
the arrow gets there. GRANT: One of the advantages of filming archery
hunts is the ability to watch the shot – frame by frame in slow motion. We’ve noticed there’s usually a delay
between when the arrow was shot and the deer starts to react. GRANT: Often, it seems, the arrow is halfway
to the deer before it starts to react. It’s almost impossible for hunters to notice
this when they’re taking the shot. GRANT: After years of watching this, I finally
asked for professional assistance to understand what was going on. I made this request on GrowingDeer right here
at the front of the barnwall and Darren Cummings, an engineer and bow hunter from Pennsylvania,
responded. GRANT: Darren used his engineering and bow
hunting skills to help us design some research to figure out what was happening. GRANT: After watching several video clips
of deer reacting to a shot, Darren developed a machine – a one-of-a-kind – to help
us test some theories and illustrate what’s happening when deer react to a shot. GRANT: Darren’s machine included a sensitive
mic that could detect when a bow is shot. It then used the speed of sound to calculate
the time between when the bow was shot / the arrow was released; and the arrow reached
targets, or deer, at 20, 30, and 40 yards. GRANT: The science goes much further. Darren used the reaction time of Olympic sprinters
to estimate how much time it would take once the sound reaches the deer for them to start
responding. Then, we used the speed of gravity to determine
how fast a deer should drop. GRANT: Now remember – deer are not connected
to the ground. They can’t pull theirselves down. So, they’re dropping at the speed of gravity. GRANT: After a lot of testing and reconfiguring
and programming, and all those engineering things, it was time to bring Darren and the
machine to The Proving Grounds and do some research. GRANT: To help us with this research, our
friends at Redneck Blinds loaned us their producer who has a super-cool, high-speed
camera. GRANT: Once all the equipment and players
were in place, it was time to test. During the first day of our field work, I
reduced the weight of my bow to where it was shooting an arrow at 258 feet a second. As another benchmark, intern Luke from Virginia
was shooting an 80-pound bow and it was shootin’ 306 feet a second. As a bow hunter, the results of this research
were eye opening. DARREN: Yeah, so you would expect at 20 yards,
if the balloon drops two inches, then at 40, it would drop four. But that’s not the case – it may drop
eight or 16. And the reason for that is because gravity
accelerates the balloon the longer it has to act upon it. GRANT: Yeah. So, we can get away with some boo-boos at
20 yards that would not happen at 40 yards. if the deer is responding to the shot because
they have more time and, actually, they’re dropping faster now… GRANT: I’m good. I’ll be the first one to get embarrassed
here. UNKNOWN: Let’s try the table. GRANT: Man, I gotta tell ya, this is eye opening. I’ve been an archer for decades. I was about center of the balloon, but it
dropped, so my arrow went right on top of the balloon. Probably would have been a spine or a high
shot. This is the reason we always aim low. DARREN: This one’s bigger, but it doesn’t
have quite as much water. GRANT: As a brief summary – using my bow,
shooting at 258 feet a second, a deer could drop two and a half inches. I was shocked. I never see that while I’m hunting. GRANT: At 30 yards, a deer could drop six
inches and at 40 yards – 10 plus inches. Depending on where you were aiming, the deer
could literally drop where the arrow got to the deer after it dropped out of the way. GRANT: Even with Luke’s 80-pound bow, the
deer could easily drop almost five inches before the arrow got to the 40-yard target. GRANT: We planned on airing these and more
detailed results after the first day. But, when we were compiling the data and reviewing
the footage, we realized we could improve our research. GRANT: We scheduled another day and in between
added stakes every five yards. GRANT: And with side view cameras, we could
really get a measure on how far the arrow was before deer started dropping. With Tyler’s setup, shooting about 270 feet
per second, we were surprised that the arrow made it about halfway to the balloon or the
target at each 20, 30 and 40 yards. GRANT: You may question why it made it halfway
at 20 and 40, but remember, it takes longer for the speed of sound to get to 40 yards
than it does 20 yards, so the arrow has more time to travel before the deer can possibly
react. GRANT: Wanting to push the limits a little
bit more, we added a crossbow to round 2. GRANT: After reviewing a lot of video clips
of hunters shooting a deer in the field and having fun doing our research, we came away
with a lot of observations and conclusions. We know that some deer react to shots and
others don’t. GRANT: We suspect this has to do with how
alert deer are. And we know from research that deer that feel
more pressure are more alert, more vigilant, than deer that aren’t. For example, research has shown that elk in
areas where wolves are, are much more vigilant more minutes out of the day than elk in areas
where wolves are not present. GRANT: Most bows on the market shoot 260 to
310 feet per second. And at these speeds, deer are likely to drop
some, or a lot, at 20, 30 and 40 yards. GRANT: During our research, we shot bows and
a crossbow with speeds of 258 to 315 feet per second. GRANT: Following is a graphic that shows how
many inches deer can drop at these speeds at 20, 30 and 40 yards. GRANT: Our team come up with a list of practical,
applicable, in the field take-aways from this work. Not all deer dropped. But it’s impossible to predict which deer
will. So, all shot opportunities should be evaluated
based on the assumption that deer will react to the sound of the bow. GRANT: Most hunting bows and crossbows are
not fast enough to hit a deer in the vitals if at 40 yards it reacts to its full potential. All shots at deer should be aimed at the bottom
third of the vitals. GRANT: That way, if they do react, you have
a safety buffer. GRANT: All the GrowingDeer Team members practice
with their bows a lot. But now, after doing this research, we all
prefer a 20 yard or closer shot. GRANT: We’ll take 30-yard shots at deer
that we evaluate to be calm. We will very carefully evaluate 40-yard shots
but probably pass most of ‘em. GRANT: We’ll continue practicing and suggest
you do also at distances greater than 40 yards so we’re very accurate at 30 yards. GRANT: While reviewing a lot of footage to
prepare for this research, we noticed – and it appears – that deer with their head down
can drop their vitals faster than deer with their head up. We believe an accurate explanation is that
when a deer has its head up, it can’t drop any faster than the speed of gravity. It can’t grab the ground and pull itself down
any faster than our balloon was dropping. GRANT: When a deer has its head down and it
hears something that alerts it and it wants to get out of Dallas, it throws its head up
which probably serves as leverage to push the chest down. The muscles can react faster than the speed
of gravity. GRANT: I remember a hunt years ago when I
was in Georgia. Some does had come in behind the stand and
were very alert. One of them finally passed the stand and started
feeding in a plot. I waited until I thought she was calm. She was about 20 yards away. GRANT: I quietly pulled back and took the
shot. I was shocked when my arrow sailed over the
deer and we reviewed the footage and saw dust come up because it appeared her chest went
all the way to the ground. GRANT: If deer are alert, be very careful
about taking any shot. GRANT: We know that humans are extremely visual. And we often detect any source of danger or
threat visually. Every hunter knows that deer are constantly
using their nose and their sense of hearing to detect danger. GRANT: But deer – even when their head is
down – their sense of smell and sense of hearing is probably fully engaged. GRANT: I used to wait for shot opportunities
when the deer had their head down. But after going through this research, I will
probably avoid all those shots and wait for an opportunity when the deer’s head is up. GRANT: With that said, I don’t plan on alerting
the deer to get it to pick its head up. If I alert the deer, it’s gonna focus in
on me and might detect the movement of getting ready for the shot and react even quicker. GRANT: If a deer is passing by in close range,
I’ll probably grunt or make just a little mouse squeak after I’m at full draw and
ready to launch the arrow. I just want to stop the deer and shoot at
that instant. GRANT: We doubt deer recognize the sound of
a bow going off as danger. We think they’re simply reacting to a strange
noise and doing what deer do best – avoiding danger by dropping; locking their legs; and
sprinting out of the area. GRANT: Through the years, I’ve noticed this
independent of the distance a deer is from the shot; or the brand of bow; arrow; broadhead;
or whether you’re using lighted nocks or regular nocks. GRANT: Each year – even before this research
– I received lots of questions from hunters throughout the whitetails’ range wondering
if the lighted nocks are causing deer to drop and rock out of the area. GRANT: Again, we went back to our footage
library and noticed that deer were dropping before we started using lighted nocks. GRANT: The speed, or the reaction time, seemed
to be the same with lighted nocks or without lighted nocks. This is even more evidence that deer are reacting
to the sound of the bow being shot. GRANT: The process of reviewing lots of video
footage of deer reacting to shots, going through the research, and evaluating the results,
has caused me to change how I will evaluate each shot opportunity. GRANT: We hope all bow hunters will use this
work to understand more about how fast deer can react to shots and make better shot evaluations. GRANT: One of the next phases of this work
is trying to understand if different levels of noise, more decibels, cause different reactions. GRANT: If you’re a sound engineer and you’re
really into this – maybe you’ve got a studio that can accurately measure different
sounds – reach out to us at [email protected] GRANT: I really enjoyed working on this research
project, as I have all of ‘em I’ve completed throughout my career. I love learning about Creation. But more importantly, I need to make sure
I take time every day to slow down and listen to what the Creator is saying to me. I hope you do the same. GRANT: Thanks for watching GrowingDeer. GRANT: If you’d like to stay current on
our research projects or our hunting and management techniques, please subscribe to GrowingDeer’s
newsletter. GRANT: We’re doing an illustration of how
deer could react to a bow shot. I’m aiming dead center. This is dropping. This clip was holding the balloon. You can see my arrow got there a little bit
late ‘cause I zeroed the clip.

  1. Super cool research! Never thought of doing a study like that before. Man that makes me question my choice to switch back to super heavy FMJs this year…

  2. I believe the deer sees the arrow coming. If a deer is looking away from you at 40 yards you will hit your mark. If a deer is at 20 yards and can see your arrow thears no time to react

  3. Hope you all like this video! In it we show some neat research that compares how many inches deer can drop by the time arrows (at different speeds) reach 20, 30, and 40 yards. Please share this with your hunting friends! Thanks for watching GrowingDeer videos!

  4. I personally like the longer videos myself this is a great study, I'm very glad you got the opportunity to do this

  5. Last weekend I shot a doe at 37 yards and it didn’t drop at all. I’m 14 and shoot a bow that only shoots 250 FPS. The deer seemed to be pretty alert and was stopping very frequently and was looking around. Why could this be that the deer didn’t drop?

  6. This the best hunting video I have ever watched. I felt like I was in my engineering physics classroom from my days in college. You and your staff did a fantastic job!

  7. This happened to me on Monday night. Had 2 does at 37 yds. I shoot about 260fps. Shot went right over her back even though I aimed at the bottom of her chest

  8. Awesome videos guys! Liked the real world application of this research. Look forward to the videos each week, helps me stay motivated to keep working on my little deer property!

  9. I decided years and years ago that I would never take a shot past 25 yards with a bow. 1. I never need to, archery is all about getting close anyway. 2. Deer ducking the string. 3. I don't record my hunts and shots and past 25 yards in the deep timber where I hunt it's hard to see what the arrow did out past 25 yards. 4. Past 25 yards small sticks and twigs are hard to see and can deflect an arrow easily by accident.

    I shoot a 75#dw bow and I've always felt like it helped a lot with deer ducking the string vs the old bows I had that had 60#+dw. I had many people tell me it didn't matter, this research shows it definitely CAN make a difference.

  10. Wow this info is amazing and shocking I’ve missed my share of deer from them “jumping string” it’s amazing that you and the engineers could team up to get proven facts on how the deer drop and what makes them drop I’m just amazed beyond words this will help so many people thanks guys for all your hard work and good luck in the deer woods

  11. Man I love all yalls videos but without a doubt, this was by far the most interesting video I've ever watched from y'all!! As a bow hunter, I think this subject is always at the top of the list on our minds when it comes to shooting deer. After watching this, I will certainly try to make sure I always try not to stop the deer myself before the shot and will try to only shoot a deer with their head up in the air!! The proof is in all the footage y'all have plus the research!! Thank y'all very much for all the hard work you put into this.

  12. I definitely lean more towards the auditory side of the bow. I shoot a very quiet bow and since I've shot it, I've never had a deer duck my arrow. (I've shot probably 30 deer with it) my previous bow, was louder during the shot and I had deer duck it. Volume is so important.

  13. Not a sound engineer, but do have some practical experience with the levels of noise. I use to shoot a relativity loud bow that I could count on the deer reacting to the shot. I always aimed at the bottom edge (inside 20yds) of the vitals or below the deer (past 20yds). When I got a new bow that was quieter I had a harder time on pinpoint accuracy of hitting the vitals were I wanted because when the ambient noise level (wind/machinery/waves) was higher, some deer would not react at all but some still would. That not reacting and aiming below was a little aggravating. I preferred the predictability of the deer reacting to the shot. The original bow shot in the 250fps – 260fps range. Oh from SC so this is not just a couple deer a year we are talking about, Grant would understand that statement.

  14. Thank you for all you do with ur crew Mr.Grant, I show these videos to my nephew regularly and we learn from them to make us better hunters… GREAT JOB!!!

  15. I went an shot the prime bow you guys endorse… While thinking of the deer dropping in many cases within this video I can simply understand why. With the Prime, the bow is super loud and I believe this causes them to drop so hard when watching these videos. I understand its an endorsement deal but, have you guys ever tested the sound of the bow compared to others. It was super loud compared to other leading brands. Also has low fps for 80 pounds!!!

  16. What a great video! Thanks for putting all the data together, analyzing it, and drawing conclusions that are accurate and useful. Ya'll are awesome!

  17. Thanks again for a great video! This one is probably one of your best 'instructional' ones you've done – it clearly explains why I've missed over the back a couple of times on longer shots.

  18. Just to be clear do your findings suggest speed is more important than silence? Also, would it be possible to use your video library as a sample to test bow noise as a predictor of string jumping? Any guess on what the findings would be?
    Ps this video is much better than reading a research paper. Keep it up!

  19. That is amazing research! love the channel and every video. Its like going to class every time i click on a video!

  20. I think you are really missing the point that a lot of deer are reacting to fletching noise. Blazer vanes,which a huge majority of hunters use,are extremely noisy in flight. If you watch the deers reaction in your video it is clear that i can hear the bow go off and by all logic that sound is to the deer almost immediately due to the speed of sound.
    I notice the deer actually start to drop when you see the arrow enter the frame on it's way to the deer.As it gets closer,they seem to be hearing that arrow getting closer and being it's such a noisy,un-natural sound coming at them,they are trying to get out of it's way.
    Something to consider….

  21. Dr. Grant. Bird documentary on owls and flight and silence. Need multiple microphones (sound recording devices) at known distances from shot location and mathematics will do the rest with multiple speeds like you did here. Also, SAFETY WARNING, ever sit downrange and listen to an arrow pass by at 10-15yds from shooter? Again, be safe with complete barrier but sound is traveling with arrow.
    More research needed in this area. Thank you for more insight!

  22. Wow great job on video and hard work to all that was involved! Very educational and hope some states use this in hunts ed class to educate our future hunters!!!

  23. I would like to know if a deer is more apt to drop depending on the angle the shot is taken at. Are they more apt to hear it if standing broadside or quartering away from you

  24. I made a shot at 32 yards on a nice buck, and yes he jumped the string. Only difference is he jumped UP not down. Is this a normal reaction also. I really thought I hit him but after searching for blood, hair, anything…. I determined it was a miss. Any thoughts please???

  25. You are the best and how you believe in god you can’t be any better than you are I am going to hunt today and you inspire me to hunt and I am only 10 and you make me want to hunt hope you guys have a great season

  26. What about the fact that the noise of the bow is quieter the farther away it is. Do you think the deer react less or not at all on a longer shot because it's much quieter?

  27. "Luke's 80 lb bow deer still dropped 5 inches" – that miss wasn't 5 inches unless he was aiming 3 inches from its spine. Not knocking the cool effort and research but a big factor in some misses is simply poor placement, which we all do sooner or later. Dropping is a factor but only one small factor. I think learning to read the deer's nervousness is as important. They don't drop much if any if not on edge-my experience anyway.
    Cool video, I'm paused, gonna finish now.
    Finished – again Great video! You covered what I was thinking, thanks. I will say though each needs to hunt within his ability. That being said, I'm shocked that your team will rarely shoot past 20yds. I've been shooting 50 and 60 for years now. This year 70 and 80 for practice to make the closer shots easier. I took my biggest buck at 60yrds, pass through, no issues, did a circle and ended up 40yds from shot. I'm comfortable with that but conditions were perfect for that shot.

  28. Good morning dr. Woods thank you for all the good advice and for making new videos every week it's especially nice because I'm from the area and understand the poor soil conditions I was wondering if you knew anywhere for next spring that I could rent a no till drill for planting soy beans in our area I live in Taney County thanks again

  29. I am convinced that deer do not drop at the sound of the bow….its the sound of the arrow zipping through the air that they hear. If you've ever stood downrange while someone shoots at a target you would hear what i mean. You cant even hardly hear todays bows go off but the arrow sounds like an airplane buzzing through the air. Whoever invents a silent arrow/fletching wins!

  30. something does not compute here ! 50 yards = 150 feet so shooting a bow at 300fs(feet er second ) means that the arrow will be in the or at the target after only half a second, the average human reaction time.

  31. I always thought it was silly to mouth grunt unless it is absolutely necessary because you put the deer on alert. Seems these videos online they mouth grunt just to get that pretty look before the shot. I haven't had a deer duck the string so I am either lucky or my bow is super quiet. I do however aim for the lower third as an exit not as an entrance.

  32. The most scientific and informative post I've seen on boe hunting whitetails. I hope we see more posts of this quality on every topic.

  33. Instant subscription. Nice work. I have killed a lot of deer with a bow, and I've never put a lot of thought into them jumping the string. I guess most of them were close. But now I have planted a food plot, so I was thinking about practicing up to shoot farther. Maybe not.

  34. Here’s a question regarding this research, if the deer is using the speed of gravity to drop, would a deer with a heavier body weight drop faster than a deer with a lighter body weight at the same distance and same reaction time? Considering heavier weight tends to fall faster. Or with the distance from the ground, there is not enough time to determine the difference?

  35. Props to the Growing Deer team, great videos. Question for you, I read that you can’t plant Brassicas in the same place every year due to disease. Is there any truth to that? I figured as long as the PH was right with adequate N it wouldn’t matter.

  36. I am a very young hunter I am 17. I hunt with a 7mm08. I was going to ask if you could do a video of the different parks to guns are different kinds of guns how they perform where it’s best to Use them and different calibers like a 12 gauge 308-3030. 30 odd six And the best ammunition because rifle season is coming up very soon for me and I would like to have your info I understand you’re very busy and I thank you for taking the time to read my comment

  37. Speed with hunting weight arrow along with a quiet bow is key. But you never know what they will do. Ive had them drop. Jump and lunge forward at the shot over my life time of hunting

  38. How does this information change when sitting 20 ft up. With the increased angle is the spot we should aim at change by the same number of inches?

  39. We apologize for ads showing up in this video. Youtube is forcing these ads because of a system error. We are working with them to get the ads removed. In the meantime – hit that skip button or click on the x to get the ad off the screen. We really dislike these annoying ads and are not trying to take advantage or annoy our viewers. We hope this is removed soon!

  40. Great video! I've studied various kinds of fletching and their resultant sounds in flight and the effect is eye, or should I say ear, opening! From my observations, if one has a quiet setup, the deer are more likely to jump the sound of the arrow in flight than the string.  I've stood behind cover near targets, and I daresay that despite not being in optimum athletic condition, I certainly 'felt like' I could have dodged an arrow even from a 330fps crossbow at 25 yards, in alert mode!

    (Note to any potential Buckaroo Banzais out there, DON'T try that at home!)

    Obviously, the high helical fletched arrows are the loudest, as they produce greater vortices, and it follows that fletching that is rounded at the rear, or 'parabolic', exacerbates the problem. In my experiences, 2 degree offset or lower vanes which are shield cut are noticeably quieter, and interestingly, the BVT vanes by Easton, were especially so. At least from my setup.

    Deer are much less likely to jump if the atmosphere between yourself and your quarry is already filled with familiar sound waves. For instance, a well timed doe bleat starting just before the shot and continuing through, tends to mask the sound of the arrow in flight, even causing many deer to freeze and raise their heads, which work very well in the hunter's favor. If one is good at approximating these calls verbally, it is simply a matter of practicing to become accustomed to not let it affect your shooting.

    Just FYI.

  41. Thank you for this information – it is critically important to archery hunters. This is a really thorough and scientifically-sound approach explaining, and more importantly visualizing, the mechanics of deer jumping the string and the relationship of what we call in my line of work, "the tyranny of distance."

  42. I would like to see some research into whether or not a deer can hear the arrow coming. Also I would like to see how deer react with out the arrow coming towards them.just the sound and not the projectile.

  43. I should have went out today. My cousin was in from Virginia on rout to Washington to see the family. Today was her last day and I didn’t want to miss sending her off. I thought she was leaving in the morning so I didn’t go out. She ended up leaving at noon and I would have been back by then. I went to a movie with my sister and could have went out for a few hours after, but I opened to mess with my cameras instead. I pulled the cards on Friday after a morning sit and my cameras had no cards in them. I need to get at least 1 more card! I was a little baffled why I didn’t see any deer that morning when all the footage 8mhave has them moving through that area in the mornings and right before nightfall. Turns out there was a bird watcher looking at the sandhill cranes miling around my spot. I’m hunting a forest preserve and he has the right to be there, but he looked straight into my camera and you can see my stand. Plus it’s posted that there is an archery hunt going on. I am all for him enjoying creation, but there are plenty of places to see the cranes, they are migrating, and he didn’t have to sully my spot.

  44. I'm glad you guys made this video if for no other reason to drive home the point that being a bowhunter means you accept the limitations of your weapon of choice.
    Every time I hear someone say they take a 50-yard shot at a deer and then justify it by saying "I practice 50 all the time" they make it clear that they really haven't figured out what bow hunting is all about.
    Also, your research seems sound but from my experience with hunting videos that I have made your number seem VERY conservative.
    I believe deer drop much more than 2 1/2" at 20 yards.
    Great video, thanks for posting!

  45. Superb! Thank you, GrowingDeer.tv team, for another hugely insightful video. The biology lessons that you share are countless. Combining those with lessons like this on physics makes this channel truly special. You bring such sophistication to the world of hunting. Thank you, keep up the excellent work and God bless!

  46. It's great to see some scientific research on string ducking. I have watched this video in the past, and I thought it would be a good idea to watch it again right before the 2019 deer season comes in. Opening day is September 7th for me, Super excited!!

  47. I know this is an old video but man is it a good one! Extremely good info here! One question. I see on the test that the bow shooting 258 that the arrow impact was already a couple inches high at 30. Then the bow that was 80 lbs shooting 300 fps that arrow at 30 yards impact was a bit low. I slowed down the shots to look at each shot in correlation to the balloon before the shot. I marked my screen for the center of the balloon. This may be the reason you are getting a skewed result because it doesn't make a lot of sense that there is only a variance of .25 inches between the 276fps bow and 308+ bow at 30 yards then you look at the bow shooting 258 and it's more then three inches in variance. I can see how human error could have potentially made the results a bit of. A hooter shooter would have been better in my opinion that way it takes out human error.

    I'm not trying to take away from this research at all. Just giving my .02 cents on how this could be done a little more accurate. This is a video all bowhuters should watch.
