M175
Versatile
The M175 low-frequency 12 kHz, 24 kHz, and 28 kHz arrays produce good bottom detail in deep-water. The 28 kHz packs up to 3 kilowatts of power in a compact, moderately-priced transducer. The 38 kHz model with 34 elements produces very high source levels, allowing deep-water detection of weak targets. The highly efficient and highly sensitive ceramic-element arrays provide exceptional deep-water fishfinding.
Applications
Deep-water survey
Mid-sized commercial fishing vessels
