The AOI SL-101 Signal Light is a compact underwater signalling device designed for dive safety and communication. In single-colour mode, it emits a bright visible light beam to signal your dive buddy, boat crew, or surface support — critical for low-visibility conditions, night dives, and blue-water environments where visual contact can be easily lost.

Compact enough to attach to your housing rig or BCD, the SL-101 adds a layer of safety to every dive without adding significant bulk or weight. A straightforward safety essential for any diver who values visibility and communication underwater.
