Whistler LRM-360 provides expanded laser coverage for the front of a vehicle. This is an add-on for Pro-3600 laser/radar detector. Size: 3.54" x 1.74" x 0.90", color: black.
Keep in mind that laser detectors act differently than radar detectors. Since the narrow laser beam produces very little "scatter"- random bits of electromagnetic energy bouncing down the road -it is much harder to detect than a powerful radar gun that blankets the countryside with easily detectable microwave signals. Laser guns operate exclusively in instant-on mode and usually target vehicles at short range. Similar to instant on radar, if you are the target vehicle don't expect much warning. The result is your laser detector usually will offer less advance warning because at 1000 feet the beam is only 3 feet wide and that the officer aims at your license plate or headlights. The distance from where your detector is mounted to the license plate can be greater than 3 feet. This will be outside of the laser beam. If the officer is not steady while targeting vehicles, scatter laser signals can result, giving a possible signal to detect.
