The ULB-350 underwater beacon is a compact, rugged and reliable acoustic signalling device used for marking equipment and underwater sites. Ideal for applications when size and weight are an issue.
The ULB-350 can be ordered in many configurations in terms of acoustic power output, frequency, and time delay. Using an off-the-shelf 9 volt battery adds the advantage of cost-effective maintenance. The ULB-350 continuously sends out an acoustic signal for up to 40 days.
