What device is this?

Was browsing youtube and found this :

At 1m 15s the guy uses some kind of half-tube atlatl arrow device.    
Unfortunately, my Korean is as poor as can be, but do any of you know what it does?

Love the distances they shoot at

I'm not exactly sure, but I believe I've read somewhere that it is to reduce the paradox.

[SveinD]

That's what i was thinking as well..
Probably increases speed and KE.. Accuracy is probably the same..

It looks too like an overdraw device,it looks like the arrow is a lot shorter then his draw length.Cool video

Looks to me like they are expounding on the manner in which this device helps arrow flight, making the arrow hit straight on and thus get great penetration.

Looks like by "shooting them out of a tube" it reduces the paradox, as stated above and it appears to me to be a way to get their cane arrows to be flying well without the benefit of tuning as we are doing here.

The slo-mo video of arrow flight difference is a clue.  

Beyond that. . .  it is humbling to see them hittting those targets at what looks like a mile or more ( OK  100 -  200 meters . . .  May as well be a mile).

Very interesting.  I wish I know what they were saying particularly the part about which side of the bow they shoot off.  I think they may shoot of the opposite side so they can over draw that much and anchor to the face with the shaft while allowing the arrow to paradox away from the face.

An overdraw device. Shorter arrow means more speed and less archers' paradox.

How cool was that? Way! I've never seen this device before but I'd sure try one just for fun!

I wish we had someone who could tell us what he was saying. I got the distinct impression at one point he was explaining why a release with one point contact with the string was better than a three point(thumb vs fingers) draw and release. That's the way I saw it anyway.

Thanks for sharing.
God bless,Mudd

PS if anyone knows for sure, please enlighten me/us. Thank you!

Don't know much about what they are saying, but the sequence where they are showing the arrow on the left side of the bow then moving it to the right side is in referance to the "Thumb ring" when using this you shoot the arrow off the right side of the bow if you are right hander,so the rotation of the string pulls the arrow into the bow,   Real Clear aint it ??

They were also shooting off the right side of the bow with the overdraw device

Ok that is Modern Traditional, Thumb ring, string loop and and overdraw. Very interesting indeed.
