I’m thinking about getting one of these and am looking for reviews on here. I see that it is advertised for ranging reflective targets (Rock, trees,, steel???) to 1800 yards and non reflective (deer, game, etc.) to 900 which is good enough for me. Who has experience with this rangefinder and what are your thoughts? Am I correct in that rocks, trees, steel plates, classify as “reflective” targets?
