I have been using the G7's(gen1&2) since their introduction with excellent success. The built in ballistics calculator has been rock solid with several dozen game animals and coyotes taken as far as 1200 yards. For skittish critters like coyote and whitetails, IMO, the speed of the on board ballistics can make the difference between a shot and no shot. I also own both versions of the Terrapin/Kestral, and a Sig 2400. All are excellent rangefinders, but I invariably find myself using the G7, preferring the control features for this kind hunting.Thanks for the info, glad to hear from someone who ranges in the snow. I haven't used a rangefinder with Ballistic calculator built in. Sounds like they work pretty good. It might speed me up and allow me to get on target faster.
