How effective is the Blinder M-10 on jamming today's laser guns? I know my unit about 3 years old & loves to false in bright sun light but I was wondering if it was still effective at jamming laser. (Drying out the heads & replacing the lenses did not help the sunlight falsing so I just do not use it on sunny days. ) I have checked it with my Bushnell 400 laser range finder & both heads have no problem picking up the laser & alarming immediately. It has never jammed the range finder from day 1 but it was not designed to so no big deal. Just wondering if I had any protection at all from the newer guns.
