Airmar
M176
Unparallel Deep-Water Fish finding
The M176 transducer is available in a low and a mid-frequency. Single or dual-frequency models feature high efficiency and sensitivity for unparallel, deep-water fishfinding and surveying. The versatile housing accommodates 12 kHz, 28 kHz, or 70 kHz with a 200 kHz array.
Applications
High-powered fishfinders
Deep-water fishfinding
Deep and shallow-water survey
Features
Low-ringing array allows fishermen to easily discriminate between bottom structure and target fish
Narrow beamwidth and low sidelobes result in exceptional sensitivity and provide distinct, bottom
detail
Stuffing tubes are available to form a watertight conduit for cable routing and are available in a
variety of materials to match all hull types
Matching transformer provides pure, resistive load
Can be mounted externally or adapted for portable mounting
Single or dual-frequency
All mounting hardware included
Seamless, SEALCAST™, urethane housing for long life underwater
Options
Dual-beam configuration
Impedance to customer specifications using matching transformer
Underwater bulkhead connector
Available as special order unit with 24 kHz, 33 kHz, 70 kHz, or 200 kHz array
Available as special-order unit with broadband, extremely low-ringing (Q), 200 kHz, element
Specifications
