The Airmar B275LHW series offers advanced wide-beam CHIRP transducers delivering superior fishfinding performance with exceptional coverage and clarity. Operating across a wide frequency band (42 kHz to 250 kHz), these transducers combine high and low frequency capabilities covering popular fishing bands (50 and 200 kHz) and more, making them broadband at their best.
The unique feature of the high-frequency band is a constant 25° wide beam across the entire frequency range (150 to 250 kHz), providing double the coverage compared to traditional high-frequency narrow-beam transducers. This results in crisper, larger return images and improved detection of fish and bottom structure, especially in the upper water column.
Ideal for boats 8 m (25’) and larger with fiberglass or wood hulls and hull deadrise up to 20° when using the included fairing block. The urethane acoustic window enhances durability and signal transmission.
Key Features
-
Depth & fast-response water-temperature sensor included.
-
Broad frequency bandwidth: 123 kHz total from one transducer.
-
Low frequency CHIRP: 42 kHz to 65 kHz with beamwidth narrowing from 25° to 16°.
-
High frequency CHIRP: 150 kHz to 250 kHz with constant 25° beamwidth for broad coverage.
-
Twice the bottom coverage and enhanced fish-target separation vs. narrow beam competitors.
-
Bronze construction with high-performance fairing block for optimal operation at speeds over 30 knots (34 mph).
-
Suitable for inshore and pelagic fishing, supporting depths up to 914 m (3000’).
-
Patented Xducer ID technology for simplified installation and automatic echosounder configuration.
