I bought a new Impact Archery Cosmic for my new BT dually, but since I got it last summer I was able to use it on my Golden Eagle Splitfire for hunting season. I found as long as your bow shoot's reasonably flat up to 30yrd's. The sight was great, but if you had to make a quick adjustment that it was a pain,that was my only complaint .The pin is the brightist pin I've used ever.I could see my pin way after dark but wasn't able to find my mark on a animal ,now that's bright. Although I've never used a HHA but I have heard great thing's about them ,from what I understand they have a easier to use adjustment arm.
