The MetOcean Telematics Iridium SLDMB (iSLDMB) is an innovative, rugged, and compact A-size Self Locating Datum Marker Buoy. Cost-efficient and expendable, the drifter is equipped with an Iridium bi-directional satellite transmitter, sea surface temperature sensor, and a GPS receiver.
Rugged, accurate products.
Timing with Search and Rescue (SAR) missions is critical, and only the most innovative, rugged, and accurate products can be used. When lives are on the line, coast guards trust MetOcean Search & Rescue products.
Search and Rescue
In live Search and Rescue operations, the buoy is deployed to track subsurface ocean currents, providing valuable information on where a person, vessel or aircraft may have drifted to while at sea.
Oil Spill Response
During an oil spill, the iSLDMB can be deployed quickly to help determine where the oil will drift, supporting clean-up companies with pinpointing where to focus their efforts.
Asset Tracking
If an asset of interest is lost at sea, the iSLDMB will provide subsurface current measurements to assist with asset recovery.
What our clients are saying
“The MetOcean iSLDMB buoy was simple to use and is ideal for a high-pressure situation like an active SAR event.”
“The iSLDMB is a key part of our SAR gear.”
“iSLDMBs significantly reduce overall risk to our personnel during a SAR event.”

The MetOcean Telematics Iridium SLDMB (iSLDMB) is an innovative, rugged, and compact A-size Self Locating Datum Marker Buoy. The iSLDMB was designed and tested to meet the stringent performance requirements of coastguards for Search and Rescue (SAR) operations in the open ocean. The iSLDMB design is based on the proven CODE/Davis style oceanographic surface drifters.
The inexpensive and expendable drifter is equipped with several important pieces of technology, including an Iridium bi-directional satellite transmitter, sea surface temperature sensor, and a GPS receiver. Due to the urgency of SAR situations, the iSLDMB is able to communicate critical data within real-time to the end-user with Iridium satellite services. Robustly designed, the iSLDMB is air certified and can be deployed from water vessels, helicopters, fixed wing and rotary wing aircraft. Depending on the required data transmission rate, the drifter can experience an operating life of up to 15 days.
