There is a difference. I just got oneon e-bay for about $160 shipped ( new Bushnell yardagepro sport 450 camo) in the store it was $180.It works for me. When your in a stand you have to aim a little low, if at all. I think it really depends on how far it is and what your pin will shoot,ex 1st pin might be good for 15 to 30 yards therefore you may not have to alter your aim. Up in a stand the range is very deceiving and I'm glad I got one
