Strobe Dive Lights show info...

Submersible strobes are an excellent tool to mark the location of the anchor, up-line or meeting point on low visibility and night dives. Not just a 'blinking light', these devices produce a brilliant 360° burst of intense light and can also be used underwater. At the surface, with the exception of the Nautilus Lifeline radio, nothing works better than a true strobe light for signalling your location. Strobes work well for signalling even in broad daylight, although with a more limited range.
