1 kW

Operating at 50 and 200 kHz, the TM258 features an elliptical beam from four ceramic elements. The beamwidth is narrow at both frequencies for excellent resolution in both shallow and deep water. The TM258 comes with a rugged stainless steel mounting bracket that is easy to install and has a streamlined shape. The combination of power and sensitivity has made this the high-performing transducer of choice for use with conventional fishfinders.

TM258 1kW Transom Mount Transducer w/Humminbird #9 Plug - 7-Pin

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.
