Vibration and Hand Shock from Compound Bows in Super Slow Motion

By Dave Hurteau

If you saw David Maccar’s recent post “High-Speed Video: .308 vs. Soup Can”  (if you didn’t you should) then you know that we recently had the use of some spectacularly sophisticated high-speed cameras.

http://ak.c.ooyala.com/5rMmYxYzquomRAzAOy2f60UgXAnL9VpE/3Gduepif0T1UGY8H4xMDoxOjA4MTsiGN

For this video, we wanted to see something that is normally only felt: hand shock and vibration from a bow. At 19,300 frames per second, two things jump out at me:

1. The advantage of parallel limbs

Many of you understand this, but for those who don’t, this clip shows why parallel limbs were such an important innovation in the early 2000's and why they are standard equipment on most hunting bows today. On the older D-shaped bow (a PSE Baby G ), the recoil of both limbs is directed away from the shooter, which causes the bow to initially jump out of the shooter’s hand. On the newer bow with parallel limbs (a Quest Prime by G5), the recoil of the top limb goes up, that of the bottom limb goes does, and they are cancelled out. No more jumping bows.

2. How far bow companies have come in reducing shock and vibration

In order to compare today’s bows head-to-head for shock and vibration you have to close your eyes while you shoot and really concentrate. The difference between today’s bows and yesterday’s, however, is obvious—even, well, shocking. You can see it here. The Prime shows virtually zero hand shock compared to the Baby G. Even top-end bows from only three or four years ago can send a small jolt through your hand compared to today’s best, which are wonderfully, spectacularly smooth. For now.

Man thats awesome to watch, look at the arrow in the quiver on the old bow, look how much it flexes!

Shot my old HighCountry the other day, a fast bow in it's era. Boy was it noisy and a lot of shock compared to my Mathews. Cool video.

Very cool video, its crazy to see that much difference between the two styles.

Great video. It just shows how much more efficiently the energy is transfered to the arrow, and not lost in the bow. I imagine this is also a large factor in how many newer bows can withstand a dry fire better than older bows... not that I would recommend it either way.

I would love to see this done comparing a recurve and longbow.

I'm with you Buckhunter, I can only shoot a couple dozen out of my recurve before my elbow starts to ache. I am only speculating that is what is causing it.

I noticed in the first video how much the top "Limb Saver" moved around! Great examples! That's money in the bank!

No stablizer on the second bow. That saves a lot of weight. The second bow also has a string dampner which stops the vibration quicker.

Wow! Great post and great video! I LOVE the super slow motion stuff!

I'd like to see a video of my old Bear Polar II at 19,300 frames per second. Its so heavy it probably don't even move.

Yes, it would have been better if the two bows had identical add-ons, stabilizer, quiver (watch the arrow in the quiver in the first clip), string stop. But to illustrate the advancement in technology it is fun to watch.

When I upgraded to a parallel limb bow a few years back, I can now see why I made immediate improvements in accuracy.

I would have liked to have seen both bows set up the same to give you a really good look how both reacted. I don't disagree with the outcome, just would have liked to see it performed more like for like. More of a true depiction as they say.

It seems that my old bow still kills them dead. Dead is Dead

Hutter,
No doubt about it. Nothing wrong with old bows. They get the job done.

I too would love to see the same gear on both bows for the shots - especially an arrow on the second bow because the arrow flexing in the first shot was incredible. I would also like to see a series with different bows because now I am wondering how my BowTec Assassin would fare...

None the less, a big THANKS for showing us this series!

thats pretty awesome... I have a Bear Whitetail Hunter and I shot at a doe this past fall with it, my buddy recorded the video and you can hear how awful it vibrated and thats with as much silenced equipment you can put on one of thos old dogs lol
