for those not venturing far from a vehicle, nothing can touch the military barr & stroud, or wild rangefinders. all the rest are junk compared to those. they will work every time regardless of conditions. if you can see the target you will get a range. ive been using a barr & stroud for over 35 years. i also recently bought a wild on ebay which is as new. ive owned 2 swarovskis one of which i bought recently. im questioning my sanity for buying it. forget the damned reveiws, and what others tell you about them. go out and use one then decide.
