I am going on my first elk hunt this fall in Colorado (rifle). I have Vortex 10x50 binos and a tripod. What is a reasonable distance to be able to spot elk with that setup? My son is going with and I have a set of Binos for him too. I have upgraded my pack, boots, his boots, range finder and some clothes (and bought myself a new bow) so this has been an expensive year already and I haven't even been hunting yet. I don't want to buy a spotter this year if I don't need to.
