Buy a nikon.......they work the best! i have a 550 ...My friend had a bushnell,during last year turkey hunting we tested each others. his was not even close to being accurate! He went out and bought a 550 the next day. He blamed missing a buck in the previous Archery season on that rangefinder.It was almost 11yrds off! Nikons are about 170+ - online at Gandermountain.
