With close up view of the bow hand and slow motion playblack we can clearly see and compare the difference in handshock between 2 longbow models.

Definitely a difference. That Satori is rock solid at the shot for sure.    

Did you shoot the same weight arrow out of both bows?

Good video but it wasn't completely clear; is it the oscillating of the string back and forth that causes the 'shock'?

Wow, that was good. Check out the web page for those bows Arni.cz. Look like very nice bows and FAST.

Not my video. Just sharing. I am assuming they are the same weight arrows or the comparison would be pointless.

Man that's an eye opener. Thanks for sharing. God bless.

Yeah they make some nice bows. There's is another clip that shows the Satori being chronoed. The bowyer won the European championship 2012 with it. Not made in USA though.

What constitutes a "common" long bow?

Different bows, riser weights, styles, tillers, string materials, arrow weights, etc. all affect hand shock. Some is more noticeable than others.  Difficult to say whether either of these produced objectionable results, just different.

Definitely a big differece in brace height and string oscillation.

Try this for your self: Shoot a longbow with hard pressure to the target on the tight grip. Then do the same, but not hard pressure and a loose grip, a bend elbow, like you would shoot with a finger/wrist loop.
I know some bows kick, some does not much. Depends on the design and arrows and and and. But the way you shoot is also concerned.

Obviously unnamed for the same reason that poor performing bows are never disclosed on this forum. But from the shape of the grip it looks like a RD longbow from a Korean manufacturer. Also the test wasn't entirely fair. That particular Satori has a custom riser full of glass (heavier than phenolic) instead of the more attractive wood riser.

Yeah, if draw weight and string size and material, arrow weight (actually the same arrow) and fistmele weren't the same, the video has no merit....

I had a Mahaska longbow that was a real thumper with B50 (recommended by the bowyer). I twisted up a 10 strand D97 padded to 16 strands with B50 in the loops and it became a pussycat. Accuracy was great with it either way, but my elbow couldn't take the pounding I got with the B50. The D97 eliminated the hand shock, but my shoulders just couldn't take a steady diet of 55# anymore, so I sold it.

As Zbone said, if all else is not equal, it's just an advertising gimmick.

The brace height is lower on the Satori which actually gives it a disadvantage yet it performed better.

Lower brace height gives a disadvantage?  In regards to handshock or in regards to arrow speed?   I think it's a great video and a cool way to illustrate hand shock, I avoid high hand shock bows like the plague.

Lower brace height will produce faster arrow speed and more handshock. The limbs are accelerating the arrow for a longer distance and both limbs and arrow reach a higher speed before hitting brace.

I have done quite a bit of high speed video, but i typically concentrate more on what the limb is doing. the bows limb timing and balancing mass weight in the limbs to the pre load.  This is determined in the limbs design, and brace height will make very little difference in hand shock....

here are a few HS video clips for you to look at.

Thanks for sharing Kirk. I agree correct limb timing and a heavy riser can elminates much of the handshock but they still exists and brace height do make a difference. My recurve becomes shocky if set below 7 1/2".
