Was coming home today after riding around town, which I found a state trooper car sitting in a grocery parking lot who left his rear Ka radar on while in the store did a few drives by his car too, had a Dual Ka radar system, only the rear was turned on. I actually thought it was a Cobra false (had gotten one while in town on Ka :roll until I saw the car.
Anyways was moving along going only about 10 over cause the road has a lot of turns and hills on it when I start to get a K band alert, so I slowed to the PSL and was going down a slight hill and a pretty sharp curve and about mid way through the curve a Parish Sheriff went flying by me. Had I not had the Pro 73 most likely would have picked him up too late to slow down. This is the 2nd time now the Pro 73 has proven itself to me that it can detect over hills and pretty good curves.
Hard to say the exact distance I got as far as alert but it would be around the 0.5 miles mark.
