This green version gives a green light. The Glo-Toob GT-AAA Pro is a small waterproof marker light used by divers, boaters, campers and rescue and tactical teams to mark people, gear and positions. Its clear polycarbonate body shines through 360 degrees and it is rated waterproof to 200 m. A simple twist of the cap turns it on and cycles the modes: constant 100% (about 5.5 hours), constant 25% (about 27 hours) and a 1 Hz flash. It runs on one AAA alkaline battery, which is included, and has a key ring for clipping it to a bag, BCD, tent or life jacket. It is 72 mm long, weighs about 30 g without the battery and works from -20 to 80 °C. Listed as end of line by the distributor.
