M42
Clearly See Bottom Structure
The M42 is a large, “blister-mount” housing which accommodates 24 ceramics resonating at 38 kHz. The narrow-beam, low-ringing, 38 kHz array allows fisherman to see bottom structure clearly and to easily discriminate between bottom structure and target fish.
Applications
Commercial fishing vessels
Features
38 kHz ceramics for incomparable, deep-water, fish detection when paired with a high-powered echosounder
Low sidelobes provide clear, bottom detail
Fairing vertically orients sound beam for stronger return echoes resulting in optimal sounder performance
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
Can be mounted as an in-hull in a fiberglass hull for precise echosounding—even at speeds over 20 knots (23 MPH)
Streamlined shape minimizes drag
All mounting hardware included
Seamless, SEALCAST™, urethane housing for long life underwater
Specifications
Weight: 13.6 kg (30 lb)
