XTAR SD-1 Multi-Colour Dive Beacon Details

Designed with diver practicality in mind, the XTAR SD-1 features a simple twist-switch operation that allows easy mode selection even while wearing gloves. The integrated low-battery indicator automatically reduces brightness to warn of diminishing power, helping prevent unexpected shutdowns during a dive. Constructed from aircraft-grade aluminium with an anti-corrosive finish, the SD-1 is built to withstand harsh marine environments while remaining lightweight and compact. In addition to underwater use, it is equally effective for surface activities such as night snorkelling, marker identification, or emergency signalling.
