Just did some further testing last evening with the No Peep Vs the Peep sight on my string. I found, under low light conditions, that the sight pins were still quite visable thru my string peep sight, but I had difficulty seeing the black dot in the green circle on the No Peep. As my reason for using the No Peep was to be able to acquire a sight picture during those last few moments of "shooting light", I have concluded that this device doesn't meet my requirements. Thanks for the input from all you "No Peep" users. I don't mean to knock the product, it's just that it doesn't offer the improvement over the string peep sight I was looking for. Guess mine will go up for sale now.[&o]
