✅ Signal Light for Location - The SD01 is designed to provide high visibility in underwater conditions, ensuring that divers are easily seen by other divers and boats. By attaching the SD01 signal light to diving tanks or BCD, it becomes easy for your buddy to locate you when diving in dark or deep sea conditions. It can also be used for other night outdoor activities, such as camping, caving, group outings at night, team tag, etc.
✅ Long Battery Life - This dive marker light is powered by an AAA Alkaline battery, and the light can work continuously for up to 108 hours, allowing divers to stay underwater for extended periods without worrying about the signal light losing power. The flash frequency is set to three flashes per two seconds.
✅ Waterproof Design - The diving strobe light is fully waterproof, with high-quality double-sealing waterproof O-rings, allowing it to be used in any type of diving environment without fear of damage from water exposure.
✅ Easy to Use - The SD01 scuba tank light is designed for ease of use and features a twist on/off switch at the head, making it very easy to operate. Tightening the head turns on the light, while unscrewing the head turns it off.
✅ Lightweight and Portable - The SD01 diving beacon is lightweight and compact, making it easy to carry and use during diving trips. Its small size also makes it easy to store in a diving bag or backpack when not in use.
✅ Available in Five Colors - The SD01 is available in blue, white, green, red, and orange, giving you a colorful and interesting underwater diving experience. Your diving trip will no longer be monotonous! Friendly tip: Each LED light only has one color. Packed with an exquisite EVA bag, the SD01 makes for an ideal gift and must-have scuba gear for your divers.
