The Airmar B175C-20-H series is engineered for high-resolution sonar imaging in challenging marine conditions. With a permanently tilted 20° element for 16°–25° deadrise hulls, these transducers deliver precise downward beam targeting—no fairing block needed.
You can choose between two high-performance options:
Standard High-Frequency (130–210 kHz) for sharper detail and accurate returns from depths up to 1,000 ft.
Wide-Beam High-Frequency (150–250 kHz) offering a 25° constant beamwidth, giving anglers twice the coverage beneath the boat—ideal for spotting targets in the upper water column with exceptional clarity.
Both variants support CHIRP-ready systems and are fully compatible with Raymarine via a Mix-n-Match 11-pin connector. Requires additional cable A80328 (single) or A102146 (pair) when integrating with Raymarine systems.
