Diveable Trigger Operated Flashlight. Featuring an incredible 1200 lumens that delivers unparalleled underwater illumination, the Princeton Tec Sector 5 is a premier dive light. The unique trigger switch makes for an entirely glove-friendly light; a half-pull provides a momentary-on option, while a full-pull of the trigger switch activates a constant-on mode. This IPX8 rated flashlight is waterproof up to 100 meters, and also locks to prevent accidental activation while in storage or during transit.
