The SLB is a Xenon Strobe Light Beacon. It can be deployed for very long periods in water depth up to 6000 m. If one uses the Kantseals, which are standard from the factory, the mooring time is mainly limited by the self-discharge of the batteries.
The beacon helps the finding of deep-sea landers and underwater moorings that have been released acoustically on a specific command or other surfaced marine platforms as remotely operated vehicles (ROVs) or autonomous underwater vehicles (AUVs). This assistance is useful at night and with line of sight conditions. With additional equipment of the MRB (Marine Recovery Beacon) series of products, one has the means to recover one's instruments at any time under any environmental circumstances. When submerged the strobe is inactive and will switch on when surfaced. To better attract attention, the flasher can be set to permanent flashing or periodic bursts.
