Ok well I have a rifle, good rings, scope, bipod, and plenty of ammo. What is the next most important peice in a ELR shooters bag? I have a very very cheap spotting scope, should I look into replacing that? Do I need a good range finder vs. using gps yardage measuring on ranging through my scope? I by no means want to be that guy with all the gear and no abilty to use it but I want to have the right gear so as I am training I am do so with what needs to be used. Any advice?
