Isn’t aiming with both eyes open the way to do it? I learned to do that in the military to keep your situational awareness and never stopped. Also, it works really well with a holographic sight, like you’ve got the red dot / reticule floating on the target.

Both eyes open is great for the real world. Olympic target shooting is a very different animal. Don’t think of it like normal shooting. Situational awareness is not a factor. Unlike practical shooting, tunnel vision is desired. Most shooters wear covers to obscure the off side eye. They are focusing on absolutely lining up the physical sights, no optics in Olympic pistol shooting.

Yeah the hand in pocket is pretty common in Olympic shooting. Unfortunate that it got pointed out as it undercuts the rest of the valid unusualness of the setup.

Your eye is still open under that flap though, no? I dabbled in Olympic pistol shooting back when I was doing across-the-course service rifle, and I was told to always keep both eyes open by the dude teaching me. Same for service rifle (and later palma). I always found that closing one of your eyes fucks up your focusing. If you don't have the little flappy dealy, you just do your best to defocus/deprioritize the view out of your non-dominant eye. I actually went for quite a while without any sort of cover because it helped me avoid cross firing (which is probably more of an issue with across-the-course than with Olympic pistol).

You're absolutely right about the lack of spectacles though. This guy is one hell of a marksman.
