The Furuno B175HW/12 is a high-frequency, wide-beam CHIRP transducer that also reports water temperature. It is a bronze thru-hull unit with a 12 degree tilt and works across 150-250 kHz. The power rating is 1 kW, and the unit comes with a 12 meter cable ending in a 10-pin connector, so confirm your sounder takes that connector.

Our take

A wide-beam CHIRP unit working at 150-250 kHz, the B175HW/12 is built as a bronze thru-hull transducer with a 12 degree tilt, so match that angle to your hull. The temperature reading comes along with it.

From our buying guide

Raymarine's general guidance is 200 kHz for water under about 60 m (200 ft) and 50 kHz for deep water. In-hull transducers avoid a hole, but lose performance and need a solid fiberglass bottom.

Check before you buy:

  • The housing suits your hull. Airmar and Raymarine rule out plastic on a wood hull and bronze on a metal one.
  • It connects to your display, since an analog transducer needs an interface.
  • A through-hull will be fitted to the maker's guide. Garmin says its own should be installed by a qualified marine installer.
