I replaced my old G7 BR2 rangefinder with a Leica 3500.com and Kestrel 5700 Elite AB. The Leica is a good rangefinder but will not work correctly with the Kestrel. I have a 1300 yard range and plan to try bag a marmot at a mile this next fall. The Leica/Kestrel works best if I leave Bluetooth off, get my range and enter the distance manually. What are you experienced ELR shooters using?
