When working traffic in the real world, the equipment needs to be easy to set up, with large easy-to-read displays, and no-nonsense durability. That's what you'll find with the new Stalker Lidar RLR. Weighing in at a mere 2.3 lbs. (1.09 kg), even with the battery pack, the -Series is lighter than any comparable hand-held device on the market. The new pistol grip Li-Ion battery snaps instantly into place, and provides power for at least two shifts. Plus, these sturdy batteries will withstand more than 500 charging cycles. A model that accepts off-the-shelf AA batteries is also available. With an average target acquisition time of 1/3 of a second or less, and a hand-held range in excess of 3,600 feet (over 9,000 feet on a tripod), it is hard to imagine a more effective speed enforcement tool.
