Hi I was out shooting some steel with a couple buddies yesterday. They both ya e g7 rangefinders I had my dog kilo2000 with 8” plate at 600yards couldn’t pick it up. There was a tin building just a little closer and wouldn’t pick that up either. Battery power is good what’s your guys thoughts? I’m not happy 2000 yard range finder that won’t even range past 450 what’s that all about?
