I bought a new Mathews bow (Halon 32 6") this past January after a 6-7 year break in shooting my old
bow which was a Mathews Switchback XT. I loved my old bow but just wanted to "upgrade" to a newer one. When I started piecing it together I bought a 5 pin Spott Hog sight for it. Due to this bow being a little faster and now having a 5 pin sight on it vs the 3 pin sight I used to use the pins were too stacked together for me. I researched different 1 pin sights and settled on one by HHA. I couldn't be happier. I also never imagined that I would be shooting out to 80 yards with a bow either. Now I won't be shooting at deer at that range because as I have found out broadheads act quite differently than field tips but it's a lot of fun. A buddy of mine and I have bought 2 60"x60" targets and several other of the bags and blocks and now have a range behind his house from 20-80 yards with a target placed every 10 yards. We have come up with our own game of Horse, calling our shots and then the other has to make it if you hit your called target. It's a blast!
We have both spent/wasted a bunch of money testing different broadheads as well but that's another story. I am very happy with Gold Tip Pierce Platinum 300 arrows (29" draw @ 70 lbs) as well. Here is a link to the sight:

i can't tell you how much easier a 1 pin sight makes it vs a 5 pin sight and I have no worries that it will be an issue during deer season if a quick adjustment is needed. On most of my stands (except fields) I know where the deer are going to be and at what ranges for the most part. This is the only con I can see to a 1 pin sight but I as you can see I couldn't be happier with mine.
