The Airmar TM258 is the industry's first 1kW transom-mount transducer, redesigned with a sleeker profile and an updated rugged mounting bracket for easier installation and improved high-speed performance up to 30 knots (35 MPH). Four 50 kHz/200 kHz elements focus narrow beams at both frequencies, delivering 16 times the sensitivity of a standard transom-mounted transducer — making 600W sounders perform like far more powerful units. The elliptical beam sweeps a wider bottom area for crisp target separation and clear bottom definition.

Features:

• Depth and fast-response water-temperature sensor
• Elliptical beam covers a larger bottom area
• Compatible with existing TM256 and TM258 mounting hardware
• Bracket kick-up assembly locks in the "up" position without damaging the transom
• Accommodates transom angles between 3° and 21°
• Urethane transducer housing
• Suitable for boats up to 12 m (40 ft)
