Description
The Garmin B175HW is a 1 kW bronze thru-hull CHIRP wide-beam transducer working on a single high band of 150 to 250 kHz. Where a standard high-frequency transducer narrows its beam, the B175HW holds a fixed 25 degree beam across the whole band, giving roughly twice the coverage beneath the boat and revealing more fish in the upper water column. The flush bronze housing protrudes less than a quarter inch outside the hull and can sit on trailer rollers or bunks without damage.
With 1 kW of power and 100 kHz of bandwidth it sounds to 600 ft. This part number is the 12 degree tilt version, suited to hulls of 8 to 15 degrees deadrise; the tilted element built into the transducer accommodates the hull angle and removes the need for a fairing block. An integral depth and water-temperature sensor is included, and the transducer uses an 8-pin Garmin connector. It runs on Garmin chartplotters with a built-in 1 kW CHIRP sounder, or through the Garmin GSD 26 or GSD 25 sonar module.

What does the 12 degree tilt mean on this B175HW?
The three B175HW part numbers differ only by element tilt. This 12 degree version suits hulls of 8 to 15 degrees deadrise. The 0 degree version (010-12181-20) suits 0 to 7 degrees and the 20 degree version (010-12181-22) suits 16 to 24 degrees.
What makes the B175HW a wide-beam transducer?
It works on a single 150 to 250 kHz high band and holds a fixed 25 degree beam across the whole range, giving roughly twice the coverage of a narrow high-frequency transducer and revealing more fish in the upper water column.
Does the B175HW need a fairing block?
No. The tilted element built into the transducer accommodates the hull deadrise, so no separate fairing block is required. The flush bronze housing protrudes less than a quarter inch outside the hull.
Does the B175HW need a separate sonar module?
Not necessarily. It runs on Garmin chartplotters with a built-in 1 kW CHIRP sounder, such as the GPSMAP xsv series. Where there is no built-in 1 kW sounder it can be driven by the Garmin GSD 26 or GSD 25 sonar module.
Does the B175HW read water temperature?
Yes. It includes an integral depth reading and a water-temperature sensor, and uses an 8-pin Garmin connector.
