Low-Cost Dual-Frequency
This low-cost “blister-type” transducer combines two popular fish finding frequencies in one housing. Its design is easier and less costly to install than magneto-restrictive transducers requiring steel tanks. The dual-frequency 28 kHz and 200 kHz models offer high and low-frequencies for species specific fish finding. The single-frequency 38 kHz model features a highly-effective, thirteen-element array that has excellent, deep-water, fish finding performance.
Applications
Commercial fishing vessels
Shallow to deep-water fish finding
Features
Low-ringing, low-sidelobe, 28 kHz array allows fishermen to see bottom structure clearly and to easily discriminate between bottom structure and target fish
Narrow-beam, low-ringing, 200 kHz ceramic provides clear bottom detail and can detect small bait fish
Fairing vertically orients sound beams 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)
Fairing is easy-to-cut and will not swell or rot
Streamlined shape minimizes drag
All mounting hardware included
Seamless, SEALCAST™, urethane housing for long life underwater
Specifications
Weight: Varies depending on configuration (Call for weight)
Acoustic Window: Urethane
Material Housing: Cast urethane
