Vibration and Hand Shock from Compound Bows in Super Slow Motion

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.

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.
