G7 is in a league of it's own you'll love it, I've also stepped from Bushnell to swaro to g7. It's amazing. I've never had any issues with beam divergence the computer seems to weed out the garbage pretty well.I've heard good things about the lieca 1600b but it's ballistic profile is limited, the g7 uses exactly what you put in no generic info. For speed of use in hunting it can't be beat to 1400. Beyond that get a terrapin. I rate them with g7 considerably better 1st
Lieca 1600 2nd
Swaro 3rd.
Everything else cheaper best used inside 500, Bushnell, Nikon, leupold and other cheaper lrf's.
