Performance Insights

The AIRMAR B275LHW utilizes advanced CHIRP sonar technology to deliver superior underwater detail and fish-target identification. By transmitting across a range of frequencies instead of a single frequency, the transducer produces clearer sonar images and improved target separation.

Its constant 25-degree beam width provides significantly wider coverage beneath the vessel, helping anglers locate fish and structure that may otherwise remain undetected. This broader viewing area is especially valuable when searching for bait schools, suspended fish, or productive fishing zones.

The high-frequency operation also provides excellent resolution, making it easier to distinguish individual fish and interpret underwater environments with confidence.

Usage Instructions

Install the B275LHW transducer according to Garmin and AIRMAR installation guidelines for fiberglass or wood-hulled vessels. Proper positioning is essential for achieving optimal sonar performance and accurate underwater readings.

Connect the transducer to a compatible Garmin marine electronics system and configure sonar settings based on fishing conditions, depth, and target species. Regularly inspect the transducer and mounting hardware to ensure reliable long-term operation.

Follow all supplied installation instructions carefully to avoid damage to the vessel or transducer.
