So when the jammer goes off it is alerting that you are being shot with laser and at the same time it is sending out a jamming signal? How do you know the if the jam was succesful? Is the blinder M25 a decent unit. Up against pro laser 3 for the most part. Or a zr3 cause that intergrates with my x50. Whats the cheapest place for a zr3 and how much?
