The ULB-364EL Underwater Location Beacon is a cost-effective acoustic relocation pinger designed for long-term deployment in the rigors of offshore use. The ULB-364EL allows the user to adjust the frequency from 27 to 45kHz and rep rate to control the operational life. The beacon uses off the shelf 9V alkaline or lithium batteries.
