Before I would buy one, someone would first have to point out to me WHY you would NEED this on a multi pin sight. On a single pin sight I can understand why. This is what I shoot. It is set on 20yds adn I have marking that I can adjust for 30,40 etc. But with a multi pin sight, after you find "zero" with your 20yd pin then you go to work on your 30, 40 etc.
The only reason I can see for this sight is if you are constantly changing between different weights of points or arrow configurations for whatever reason. Even then if you moved the sight the 20 might be right but you may still have to change every other pin individually.
To me it just seems like a way to gouge money out of your pocket for something that is "new and improved"

OOOps...you said rest and I read sight...my bad[&o]
