Furuno Transom Mount High-Frequency CHIRP Side-Scan Transducer

CHIRP Side-Scan imaging optimised for shallow water, purpose-built for NavNet TZtouchXL.

The 455T-TM903 is a high-frequency transom mount transducer designed to work with the built-in CHIRP Side-Scan functionality on Furuno's NavNet TZtouchXL MFD range.

Operating across a CHIRP frequency range of 445–465kHz with 150 watts of power on each side, it delivers exceptional detail and target separation in shallow to mid-depth water.

The urethane housing is built to withstand the marine environment, and the transducer comes ready to install with a mounting bracket, hardware, and a 12-metre cable included as standard.

Suits transoms angled 0°–30° and hull deadrise up to 28°.

Features

CHIRP Side-Scan Technology - Uses a swept frequency range, producing cleaner, higher-resolution imagery with greater target separation than traditional Side-Scan.

Optimised for Shallow to Mid-Depth - The higher 455kHz frequency delivers exceptional image quality and fine detail in shallower water, making it the preferred choice for reef, structure, and bottom fishing in depths up to approximately 40m.

TZtouchXL Exclusive - Compatible only with the TZT10X, TZT13X, and TZT16X MFDs; not compatible with TZtouch3. Integrates directly with the built-in Side-Scan functionality without requiring additional hardware.

150W Per Side - Dedicated power output to each side ensures strong signal strength and consistent imaging coverage across both channels simultaneously.

Transom Mount with Temperature Sensor - Installs on most vessels without haul-out, with an integrated water temperature sensor adding useful data alongside sonar imaging. 

Ready to Install - Supplied with a 12m (40ft) cable, mounting bracket, and all hardware included, minimising installation time and additional costs.
