TM258 1kW Transom Mount Transducer w/Humminbird 14-Pin Plug
The re-designed TM258 sports a new look and better high-speed performance. The industry's first, 1kW, transom-mount transducer has an updated, rugged, mounting bracket. The sleek design makes the TM258 easier to install. And its streamlined shape will give you improved high-speed performance up to 30 knots (35 MPH).
The TM258 will make 600W sounders respond like a more-powerful model. Get 16-times the sensitivity compared with a standard transom-mounted transducer. The TM258 packs four, 50 kHz/200 kHz elements to focus narrow beams at both frequencies, so you'll see crisp targets and clear bottom definition.
