The TM258's four-element design focuses available power more efficiently than standard transducers, creating concentrated energy beams that penetrate deeper and provide clearer target definition. Your 600W fishfinder will perform like a more powerful unit with significantly improved sensitivity and target detection capability.

The streamlined design maintains sonar accuracy and bottom tracking up to 30 knots (35 MPH). The hydrodynamic profile minimizes cavitation and turbulence that can interfere with sonar performance at high speeds, making it ideal for tournament fishing and long runs to fishing spots.

The fast-response temperature sensor provides accurate water temperature readings critical for locating thermoclines, temperature breaks, and optimal fishing conditions. The sensor responds quickly to temperature changes, helping you identify productive water temperatures for target species.

This transducer is designed specifically for Furuno fishfinders with 10-pin transducer connectors. While it's manufactured by Airmar (M258), it uses Furuno-specific connector and configuration. For optimal performance and warranty coverage, use with compatible Furuno fishfinder systems.

While through-hull transducers eliminate hull interference, the TM258 offers 1kW power in a non-invasive transom mount installation. You get superior performance without drilling holes in your hull, with easy installation, service access, and the ability to easily upgrade or replace if needed. The high power and four-element design overcome most transom mount limitations.
