Frequently Asked Questions

What makes the B275LH-W different from standard CHIRP transducers?

The B275LH-W features a constant 25-degree wide beam on high frequency, providing twice the underwater coverage compared to narrow beam transducers. This means better fish detection and more comprehensive bottom coverage for serious anglers.

What extension cable is required for installation?

The B275LH-W requires Raymarine extension cable A80327 (sold separately) for proper connection to compatible sonar modules. The transducer includes a 6.6-foot cable that connects to the extension cable.

What hull materials are compatible with this transducer?

The bronze thru-hull design is compatible with fiberglass and wood hulls with deadrise angles from 0 to 20 degrees. Professional installation is recommended to ensure proper hull preparation and watertight integrity.

What is the maximum depth capability?

The low frequency CHIRP (42-65 kHz) provides maximum depth reading to 3,000 feet, while the high frequency CHIRP (150-250 kHz) offers detailed resolution to 800 feet maximum depth.

Is this transducer suitable for tournament fishing?

Yes, the B275LH-W is specifically designed for tournament and offshore blue water fishing applications. Its 1kW power handling and dual-frequency CHIRP technology provide the professional-grade performance competitive anglers demand.

B275LH-W Bronze Thru-Hull - Low & High Wide Frequency

Get more coverage under the boat with the wide beam CHIRP product line. Offering a high frequency range of 150-250 kHz and a constant 25° beam width, these transducers are truly broadband at its best. In addition to improving the performance of CHIRP-ready echosounders, anglers using the new wide beam transducers will achieve twice the coverage under the boat compared to our current high frequency CHIRP transducers.

A unique property of the high frequency transducers is that the beambwidth is a constant 25° angle across the entire frequency band. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with the narrow beam transducers, the wide beam format also creates crisper and larger return images on the display. We've got you covered!
