i have owned both the g7 and the leica 1600b.. I like the g7 better it has very good glass. and it uses the same laser system that almost every law enforcement radar uses to give you tickets.. its very repeatable out to over 2000.. I have ranged trees at 2200 and buildings over that.. gives readings in light fog if it gets remotly thick it will not read accuratly.. I sold the leica and kept the g7. the leica will only do 800 correction, which is a long long ways but 1450 is better
takes 1-2 seconds and you have a shooting solution. and you can program all your rifles and your buddies rifles so its a very good all around rangefinder!! I use that and my swaro el binos and do very well!!
