Activate the the Z-BoltŪ BTE-4S constant on/off click switch and the unit emits the highest power 635nm red laser light, projecting a brilliant ruby red laser dot. No comparison to cheaper 645~650nm red laser pointers, (the BTE-4S red laser is twice as bright) the laser has a visible range of 4,500 ft. (Night) The red laser module operates on 2 pcs AAA batteries for superior battery life - fifteen (15) hours constant on operation. Add a Z-BoltŪ cable switch for any application that requires remote activation. Ships in premium satin lined carry case.

The BTE-4S red laser pointer is constructed of high quality steel & brass components; includes a glass lens for superior laser performance; and features our special APC control circuit. The computerized APC diode drive circuit features "Automatic Power Control". This advanced circuit is based on a photo diode feedback loop. The photo diode monitors the optical output and provides a control signal for the laser diode, helping to maintain the diode operation at a constant optical output level. The circuit adds to the lifetime of the laser, prevents overheating, and provides overall power output stability & efficiency.
