As for a range finder, I have one of these. It is accurate. I also use it for my crossbow. https://www.academy.com/shop/pdp/halo-xr800-platform-6x-rangefinder#repChildCatid=7204387
Thanks, Joe for taking the time to help us air gunners.. As always, I enjoyed your review. I have a couple of Centerpoints but there is a reason. This reason is a whole other story and it is a bit long. I might tell you someday. Thanks again, Bud.
I am lucky. Most of my shooting is hunting. Both of my Marauders ,22 and .25 like Polymags better than JSB's. They are deadly on squirrels and with birds, it looks like a pillow blew up. ;o)
