Re: New sight
I got one for my wife.
It's easy enough to sight in, you zero it like any other sight...
The "retina thingy" is adjusted afterwards, and that can be a little challenging.
(it pretty much requires a second person)
Basically it gives you a second reference point to the level.
I think the biggest benefit is to help a new(er) shooter learn to have good
technique giving them a visual reference to when they are doing things the
same way. In her case she sometimes cants the bow front to back causing
vertical stringing. The retina helps her notice and forces her to correct.
I think it's a pretty nice, well built sight with good adjustments.
The retina display works as advertised and isn't "just a gimmick"...
whether it has any value to you, only you can decide. You could make the same
argument about a level. Lot's of people were great shots without levels, but
they definitely help me. I always check my level, it's usually on, but every now
and then when I glance at it, I see I'm slightly off and adjust...
As far as the USA thing... that's up to you. While I support and advocate buying
American, we all have things that aren't made here...
