HVLF and HLF Systems

These flagship systems have an impressive 40+ dB of dynamic range and some produce output as high as 202 SPL. Various configurations allow for a uniquely high-powered range of frequency.

For decades, these transducers have been used in the world’s oceans including the ice-capped poles, for both scientific research and naval missions.
