Welcome to the forum.
I suppose consideration for the addition of a laser jammer to your defense arsenal, would depend upon several factors, including:
- Where you drive and whether or not police laser (lidar) is employed as a speed measurement technology (versus radar or vascar or other means)
- If so, the extent of the use of police laser (eg; how often do you encounter it)
- The 'legality' of the use of a laser jammer in your area
- The nature of the vehicle(s) you drive, color & make
Your answers would help me provide you a considered answer.
