The Airmar TM185C-HW delivers wide-beam CHIRP coverage for Humminbird units, sweeping a constant 25° beamwidth across a high-frequency band of 150–250 kHz. That fixed beamwidth effectively doubles the bottom coverage compared to standard narrow-beam high-frequency CHIRP transducers, while the broadband signal returns crisper, larger images on screen and improves fish detection in the upper water column. A fast-response temperature sensor and rugged urethane housing round out a capable transom-mount package sized for mid-range boats.
