Question about Nikon ProStaff Laser 440 Rangefinder
Target cannot be measured at any distance. I have put a new battery in the unit and problem remains. The lens is not obstructed. The unit worked great for about four months after I got it and then it just quit measuring.
Had the same problem... Pushed the mode button and the power button simultaneously for 30 seconds, then it worked again...
