Echotrac CVM depth sounder

DESCRIPTION

CVM is a waterproof, sturdy, and durable dual frequency depth gauge. The high-frequency channel frequency range is 100KHz-340KHz, suitable for shallow water measurement and side scan measurement. The low-frequency channel range is 24KHz-50KHz. It has a larger measurement depth and is used for floating mud detection. Due to its broadband frequency input, CVM is compatible with various new and existing transducers.
