Echonautics TM70M600

600W Medium CHIRP Transducer

The compact TM70 transom mount series is ideal for small, trailered boats where a thru-hull installation isn’t practical — including freshwater boats and centre consoles. They’re simple to install and avoid the risk of a thru-hull fitting interfering with trailer loading.

The TM70 series housing shape and robust stainless steel mounting bracket are designed to minimize drag while delivering superior target detail, structure resolution and bottom tracking performance - even when the boat is moving at speed.

With traditional 600W 50/200kHz dual frequency and Medium/High Frequency CHIRP options, TM70 series is a versatile performer for many recreational fishing and leisure boats.

Compatible with major sonar brands, the TM70 matches transom angles up to 70° while delivering a focused vertical beam on targets below.

Mix and Match Adapter Cables

Echonautics transducers come with 8-meter/26-foot cables and standard 8-PIN Male connectors. One-meter/3.3-foot adapter cables are available through Echonautics.
