Furuno TM165HW CHIRP Wide-Beam Transom Mount Transducer 150/250kHz 600W

The Furuno TM165HW is a high-frequency, wide-beam CHIRP transom mount transducer built by Airmar for Furuno fish finders. Operating across a frequency range of 150–250 kHz with 600 watts of power, it delivers an exceptional 30° average beamwidth across the entire high frequency band — providing up to three times the underwater coverage compared to standard high-frequency CHIRP transducers.

A patent-pending ceramic filtering lens enables the TM165HW to maintain that wide 30° beam consistently across the full bandwidth, giving anglers more precise fish detection in the upper water column that narrow-beam transducers can often miss. The result is crisper, larger return images on the display with a maximum depth rating of 500 feet (152 m).

Key Features:

• CHIRP Technology: Operates across 150–250 kHz high-frequency band with 100 kHz of total usable bandwidth from a single transducer
• Super Wide Beam: 30° average beamwidth delivers 3x the bottom coverage of standard high-frequency CHIRP transducers
• 600W Power Output: Maximum depth rating of 500 ft (152 m)
• Built-in Sensors: Integrated depth and fast-response water-temperature sensor
• Furuno 10-Pin Connector: Plug-and-play compatibility with Furuno CHIRP-capable fish finders including DFF1UHD, TZT9F, TZT12F, TZT16F, and TZT19F
• Plastic Housing: Durable, low-profile plastic transom bracket and hardware with release mechanism to protect sensor from frontal impact
• 9-Meter Cable: Includes 9 m (approximately 29.5 ft) cable
• Recommended Use: Planing hulls up to 25 ft (8 m) in fiberglass, metal, or wood — outboard and I/O configurations
• High-Frequency Advantage: Superior shallow-water performance, bottom detail, and fish-target separation

The TM165HW is an ideal performance upgrade for anglers seeking maximum coverage and detail from their Furuno CHIRP fish finder. Its wide-beam, high-frequency CHIRP capability covers the popular 200 kHz fishing frequency plus everything else in the bandwidth, making it one of the most capable transom mount transducers available for boats up to 25 feet.
