I wanted a laser, the Newcons being binos seemed like a good idea and had the speed detector function. Much less spendy than Leica Geovids. The box looked good and so did the carrying case. The unit to me left a lot to be desired, bulky, plastic and not good optics. As a binocular very poor, as a laser eratic. One day it read a grey building over 1KM the next it struggled to do over 200m (I tried several new batteries)and weather conditions were similar. The speed detector worked but it had no scan mode. Also not waterproof. The third day it got sent back. I may have just got a lemon but I saw nothing to suggest it was a quality optic. The good news is that I bought it from binoculars direct, they will replace it with a Swarovski Laser Guide, when in stock (mid to end of April). Very good people to deal with. David.
