ULB-362
RJE International's ULB-362 is a compact and cost-effective underwater location beacon that is ideal for installation on ROVs, AUVs and other subsea equipment. Designed for use at down to full ocean depths, it is available in 27kHz, 37kHz, and 45kHz frequencies, and can transmit acoustic signals for up to 90 days.
A variant design, the ULB-362PL/C37, provides emergency location functionality that is activated by power loss through an external connector. Triggering occurs automatically when a relay closes on the host platform due to loss of power.
