This is the Garmin B75H bronze thru-hull transducer, a 600W unit with an 8-pin connector. The element is tilted 20 degrees inside a flush-mounted bronze housing, which lets it fit the hull without a fairing block. It is rated for depths to 800 feet and for 16 to 24 degrees of deadrise. The maker calls it a good match for fiberglass and wood hulls, and low, medium and high frequency versions exist.
Our take
The element is tilted inside a flush-mounted bronze housing, so the transducer sits right in the hull without a fairing block. It is rated for 16 to 24 degrees of deadrise, which is the range to check against your hull before cutting a hole.
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.
