The DB 2000 is based on the highly successful JET 2000 J navigation buoy.  It has a steel central core and can be fitted with a variety of daymarks depending on payload and power requirements.

The most popular daymark is the 1m hexagonal tower, which provides internal space for instrumentation and batteries and a large external area for the mounting of solar panels.

All Mobilis data buoys comprise a robust central steel structure with through-hull access for underwater instrumentation and cabling. Buoyancy is provided by multiple-section rotationally moulded polyethylene (PE) floats, which are bolted around the structure.

A range of towers are available depending upon focal heights, payloads, and power requirements. Towers are manufactured from marine grade aluminium and can be fitted with a large range of battery housings, solar panels, sensor rings and topmarks.

Replaceable structures can be held where a buoy requires to be quickly redeployed with a different equipment configuration.
