B765LH / B765LM Thru-hull

Product catalog summary

Overview: The B765LH and B765LM are thru-hull, Chirp-ready transducers designed for smaller fishing boats, offering the performance of larger transducers in a compact form. They feature a combination of low-frequency and either high-frequency or medium-frequency ceramics for versatile depth capabilities and fish finding.

Specifications:

B765LH: Features a 300 W low-frequency and 600 W high-frequency ceramic. The low-frequency range is 40 to 75 kHz with a beamwidth of 32° to 21°, providing depth performance up to 366 m (1,200'). The high-frequency range is 130 to 210 kHz with a beamwidth of 15° to 9°, offering depth performance up to 213 m (700').
B765LM: Features a 300 W low-frequency and 600 W medium-frequency ceramic. The low-frequency range is 40 to 75 kHz with a beamwidth of 32° to 21°, providing depth performance up to 366 m (1,200'). The medium-frequency range is 80 to 130 kHz with a beamwidth of 24° to 16°, offering depth performance up to 274 m (900').

Key Features:

Both models include a depth and fast-response water-temperature sensor.
High-performance fairing enhances broadband performance at speeds over 30 knots (34 MPH).
Exclusive Xducer ID® technology for enhanced functionality.

Design and Installation:

Weight: 2.5 kg (5.5 lb).
Recommended for boats up to 9 m (30') in length with fiberglass or wood hulls.

Catalog excerpts

B765LH / B765LM Thru-hull B765LH and B765LM are thru-hull, Chirp-ready transducers that are perfectly suited for smaller fishing boats. Both models deliver the performance of the larger transducers but in a compact package for smaller boats. The B765LH and B765LM each feature a great combination of a 300 W low-frequency ceramic and either a 600 W high-frequency or medium-frequency band ceramic for a wide range of depth capability and fish finding. The low‑frequency band provides excellent depth penetration. The high-frequency band features a narrow beamwidth (15°-9°) for excellent target separation. The medium-frequency is perfect for more coverage under the boat and delivering excellent bottom detail. The included high-performance fairing improves broadband performance at speeds over 30 knots (34 MPH). • Depth and fast-response water-temperature sensor • Depth and fast-response water-temperature sensor • 115 kHz of total bandwidth from one transducer means great shallow and deep-water performance • Covers popular fishing frequencies of 50 and 200 kHz plus everything else in the bandwidth • Exclusive Xducer ID® technology AIRMAR®...IT’S WHAT’S UNDER YOUR BOAT. • 85 kHz of total bandwidth from one transducer • Covers popular fishing frequencies of 50, 88, and 107 kHz plus everything el
