I have owned my 1998 model 1.7 V1since it was new. It has the older lidar detection system. I discovered that it will not laser alert to the UL 100LR! Not even point blank. Never. Nothing. Not a sound. Oh well, that is what the Blinders are for. Blinders had no issue detecting the same gun. V1 screams at all my other lidars, including the older LTI Marksman, just fine.
Just a worthless 1.7 V1 discovery.
