SLB 6000 Strobe Light Beacon
The SLB is a Xenon Strobe Light Beacon. It can be deployed for very long time 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 Marine Recovery Beacon series of products, one has the means to recover one's instruments at any time under any environmental circumstances. All products use the same titanium housing with double axial seals and the triggering controlled by a pressure switch. 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. All kinds of D-type batteries can be used. The number of flashes is dependent upon the chemistry of the battery from 50 000 to 400 000 at full intensity for one set of batteries. Automatic adjustment to a constant number of flashes is optional. The intensity and flash rate are then determined internally from the type of battery used.
