Get more coverage beneath your vessel with Airmar’s exclusive B175HW, a wide-beam, high-frequency, CHIRP-ready transducer.
The high-frequency band operates within a range of 150 to 250 kHz and features a fixed 25° beam across all frequencies. This high-frequency band delivers superior performance in shallow waters, providing excellent bottom detail and enhanced fish and target separation.
The consistently wide beam offers twice the coverage for detecting fish in the upper water column and produces clear fish arches on the display compared to most narrow-beam high-frequency transducers. The high-wide option is ideal for both coastal and pelagic fishing, where resolution and maximum coverage beneath the boat are essential down to 152 m (500′).
Tilted Element™ transducers have the element fixed at an angle of 20°, 12°, or 0° within the housing. Because the transducer is installed nearly flush with the hull, the tilt compensates for the hull’s deadrise angle. This orients the ceramic element horizontally to ensure maximum echo return to the transducer.
The B175HW is available in three tilted element models:
-
20° fixed tilt version for hull deadrise angles from 16° to 24°
-
12° fixed tilt version for hull deadrise angles from 8° to 15°
-
0° fixed tilt version for hull deadrise angles from 0° to 7°
FAQs
The B175HW uses a recessed bronze housing designed for thru-hull installation and minimal protrusion from the hull.
Follow included instructions, and if issues arise, contact Garmin Product Support or a professional.
The placement increases the complexity of thru-hull installations and requires careful installation.
Yes, flush-mount thru-hull transducers are often installed on sailing vessels because they produce minimum drag.
Improper installation can cause performance loss or potential damage to the boat.
This device supports CHIRP sonar technology, which requires pairing with a compatible system for optimum performance.
Proper placement is key; install as per instructions for best performance.
It should be mounted in clean water forward of propellers and running gear for optimal signal.
Yes, thru-hull transducers come in flush and external styles. Flush minimizes drag; external is for larger boats and may require a fairing.
Flush thru-hull transducers sit flush or nearly flush with the boat hull, producing minimal drag.
Yes, a recessed housing and minimal hull protrusion allow trailering without damaging the transducer.
