I am courteous if I really need a range finder for rifle hunting. Deer for now elk in the future. And some suggestions on a good one to buy. I am planning on getting new optics all the way around with Swarovski binos and spotter. Curious about the rangefinder if needed or save for the combo unit from Swarovski. I don’t know if I like the idea of the combo unit but it could save weight for backpack hunting
