Redesigned ULB-350 Underwater Acoustic Beacon

Using state-of-the-art electronics, the new ULB-350 now operates for 30 days on a 9V alkaline battery and up to 60 days on lithium. Standard frequencies still include 27, 37, and 45KHz; however, custom factory set frequencies are available between 20 and 45Khz. In addition, the ULB-350 has a time-delay activation option that can be factory set from 1 second to 90 days or, by purchasing the ULB350/PRG programmer, you can program the ULB-350 yourself. Adjustable parameters include time-delay activation, pulse width, and repetition rate. Mechanically, the ULB-350 has also been improved with dual o-ring seals and easy access to the battery compartment without the use of hand tools. The next generation in underwater acoustic beacons has arrived.
