Water Activated Tank Marker Strobe
Water activated marker lights turn on when they come in contact with water and turn off when they are dried off. Total life is 500 hours which far exceeds most marker lights on the market. These are disposable marker lights with non-replaceable batteries. Available in Red, blue and green, flashing only!
We use these markers in a commercial setting. Our divers often go solo on tether and this is a great safety feature for them. We use the green ones to mark a work area or attach them to equipment being lowered to a diver so they can find it in poor visibility. The red ones we attach to our tanks. That way if the worst should happen and the safety diver has to go in, finding the diver in distress is made a lot easier. We absolutely beat the heck out of them with the work we do. Great price, well constructed and durable, would buy again.
