Designed for paddle sports, maritime activities, and diving adventures, the Princeton Tec Meridian StrobeBeacon Light is a highly visible beacon for emergency situations. It also serves as a handy flashing light to alert nearby divers of your presence. Featuring red and white LEDs, the StrobeBeacon Light flashes in either color with the simple flick of its toggle switch. Its IPX 8 water resistant rating means it safely submerges to 100 meters in depth. Three included batteries power the StrobeBeacon for an impressive 100 hours, in case you're waiting for rescue out at sea. And because it's designed for a wide variety of scenarios and sports, it easily mounts to one inch webbing straps, PFDs, and SCUBA tanks.
