The Furuno TM258 transom-mount transducer is engineered for high-speed boaters who demand crisp sonar detail without sacrificing easy installation. With 1 kW RMS power and dual-frequency 50 kHz / 200 kHz operation, it covers wide-area scanning and precise readings at speed.
-
Power: 1 kW RMS transducer power delivers strong performance and is compatible with higher-output sounders.
-
Frequencies: 50 kHz and 200 kHz operation to cover wide and narrow scanning needs.
-
Elements: Four 50 kHz/200 kHz elements to focus narrow beams at both frequencies for precise readings.
-
Sensitivity: Delivers 16× the sensitivity of a standard transom-mounted transducer.
-
Speed performance: Streamlined design and rugged bracket provide improved high-speed performance up to 30 knots (35 MPH).
-
Installation: New rugged mounting bracket and sleek profile for easier installation.
-
Depth & Temperature: Depth and Temperature data supported at 50/200 kHz.
-
Material: High-Performance Urethene construction.
The TM258 helps you see crisper targets and clearer bottom definition, even at higher speeds, by combining high power, dual-frequency capability, and a design that maximizes sensitivity. Its rugged build and simplified mounting considerations make transom installation straightforward, while dual-frequency depth and temperature data enhance your on-water awareness in varied conditions.
