The Furuno B265LH is a thru-hull CHIRP transducer built for serious depth work on vessels 25 feet and larger. A single bronze housing delivers 103 kHz of total bandwidth, covering both low and high CHIRP frequency ranges to handle everything from inshore structure to deep-water canyon and seamount tracking. A fast-response water-temperature sensor rounds out the sensor package.

Specifications:

• Depth and fast-response water-temperature sensor
• Low-CHIRP: 42 kHz to 65 kHz, 25° to 16° beamwidth
• High-CHIRP: 130 kHz to 210 kHz, 10° to 6° beamwidth
• 103 kHz total bandwidth from a single transducer
• Covers popular fishing frequencies of 50 kHz and 200 kHz, plus the full bandwidth range
• Fishing profile: Commercial and recreational inshore and offshore fishing, including deep-water canyon and seamount tracking
• Bronze housing with high-performance fairing block
• Minimum boat size: 8 m (25') and above
• Compatible hull types: Fiberglass or wood

CHIRP Technology Advantages:

• 5 to 10 times greater detail and resolution compared to traditional sonar
• 10 to 1,000 times more energy transmitted onto targets
• Accurate readings to depths of 3,000 m (10,000')
• Precise separation between baitfish and game fish on screen
• Superior performance in acoustically noisy environments
• Improved bottom tracking at high vessel speeds
