Ive strictly shot a single pin sight for years now without any real difficulty but recently i switched to a multi pin sight. Now im shooting the Apex bone collector and im glad i made the switch. I prerange most areas i hunt and i dont see the need to take the time, even if its just for a second, to have to move my sight dial before drawing back on a deer. Now ive never had a problem with a single pin sight in the past, ive been lucky, but the more i think about it the more i dont want any problems to happen, so thats why i switched. Ive also forgot to move the pin back when shooting different ranges and have lost some arrows because of it. With a fixed pin sight i can spend my time drawing back on the deer instead of having to move the sight first and then drawing back, yes it does take a couple seconds longer to draw when you have to move your sight and you do have to take your eyes off the deer in the process. The couple seconds that i had to take my eyes off the deer to adjust that sight have always worried me. My bow shoots fast enough that im able to compensate fairly accurately between distances when i have my pins set at 10 yards apart. Things happen so fast in the woods sometimes that its nice to know that you can just draw and shoot without having to guess things. Someone mentioned earlier that you should leave it set at 20 or 25 and know where it hits at other various distances so you dont have to adjust. Im sorry, but to me, that is a very irresponsible way to hunt and im just gonna leave it at that. Too many deer get wounded every year by people guessing yardages and taking pop shots. Some people are skillful enough to get away with it, but alot of others are not. Do yourself a favor, take the guess work out of the archery equation, get a fixed pin sight and you'll do alot better in my opinion.
