When attached to a diver’s tank valve as a small marker light, the light produced with a Cyalume® lightstick is unobtrusive and can assist another diver in keeping track of where other divers are above and below the surface. Please note also that
many Surface Marker Buoys (SMB) now include a small pocket at the top of the bag that can be used to hold a Cyalume® SnapLight® lightstick aloft, making the diver much more visible on the surface in the dark.
