I really feel that most people didn't give the Tracker IV an honest shake. The disc circuit is really good for 4-6" targets.
It is not for hunting for deep targets, but for what it is built for....it really nails it.
I keep the 4" coil mounted. I use it to hunt in sports fields. It really shines in that environment.

I have half a mind to send you one of mine when you are up to swinging again lol.
