I currently use the ProSlide single pin sight and haven't had any problems with it. Very visible pin at dusk but not as bright as the Impact Cosmic single pin. The cosmic had two knobs to loosen to adjust and the Vital only had one which was my selling point.

I have to be honest I have one of there sights but it kept coming loose on me, there pins are bright but at first. I thought it was my bow because it's so fast and vibrates. So I called the company and they told me their Hoyt shooters never had a problem with them. Yeah , what ever, of course they won't they get their's for free since they sponcer them. Anyway, I sent the sight back, and they practically sent me a new one which I thought was cool. But they have these plastic washers, and I just don't think they were working out. So I got rid of them and put some pipe tite on it, so far it hasn't moved much just a little bit at times. But to be honest, I plan on getting either the copper john dead nuts or a spot hogg. Soon as I can, those right now are the best rated sights out there . As for their other products I don't know. I have a Hoyt Supertec with the Muzzy Zero effect, which I think is the best out there. I use Easton carbon evolution arrows with the crimson talon broadheads. They are definately the best broadheads you can get, but you can check it our for yourself. They have some new ones check out their web site. I plan on turkey hunt'n next week with my set up, just wish I had my copper john. But I have to wait until I have the money for it, later.
