There was a Local small town Leo shooting Ka Instant on just over an overpass. I got my first brief warning over 2 over passes and a mile away. 30 min later a Texas trooper Stalker 34.7 had made a traffic stop behind a semi truck and i got an alert 2 miles before. I got gas and got back on I-27 heading back to Lubbock and got Instant on from another trooper just as i passed an over pass. i was doing 80 in a 70 and bolted on my brakes. I was thinking i beat him to the punch he never gave chase which is very rare. Also got a 2.5 mile alert on a Sheriff with Constant K band. Maybe the trooper was lazy i dunno. Most of the time before a trooper Instant on's me point blank i always get 1Ka alert then full to 9 strength. Some of there units must leak. I have been very lucky with Instant on saves at point blank.
