My dad is a big game bow hunter and he is thinking about using the peep eliminator site. Does any one have any pros or cons about it?

Try posting in the BowHunting or BowHunting Gear forums, you may get more informational/less biased opinions there.

Good site, but takes some getting use to. Its not real hard to use, and has its advantages in low light, but your anchor has to be right on everytime(which it should be regardless). Personally, i think a big peep is better, cause it pretty much serves the same purpose as a rear sight. But, every one has his tastes. Let me know how he likes it if he gets one.
