Compact and Portable: The diving beacon is compact and lightweight, making it easy to carry and use during diving trips. Its small size allows for convenient storage in a diving bag or backpack when not in use. Signal Light for Location: The beacon is designed to provide high visibility in underwater conditions, ensuring divers are easily seen by others and boats. By attaching the signal light to diving tanks, it helps your buddy locate you when diving in low-light or dark conditions. It can also be used for other night outdoor activities such as camping, caving, night group outings, or team tagging. Friendly Tip: Each LED light emits one color only. Easy to Use: The scuba tank light features a simple twist on/off switch at the head, making it easy to operate. Tightening the head turns the light on, while unscrewing turns it off. Long Battery Life: This dive marker light is powered by a single AAA alkaline battery and can operate continuously for up to 108 hours, allowing extended dive times without power concerns. The flash frequency is set at three flashes every two seconds. Waterproof Design: The diving strobe light is fully waterproof, equipped with double-sealed O-rings, making it suitable for use in all diving environments without risk of water damage.
