The Laser grid pens are extremely durable and powered by a 18650 Battery, with the on/off switch located at the bottom of the torch and no need to hold it down like some of the laser pens on the market. These have a adjustable lens that range from a wide light grid to a sigle laser beam.

I've bought several laser grids but this us the best one ever. This pen is small and easy to carry. Hooks onto a tripod and provides a large grid. The batteries last almost an hour and a half. Perfect for a long session in any area. Extra batteries keep this going the entire night. Love it!!!
