Specifications
- Mount
- Transom
A transom mount depth transducer from Raymarine, made for ST40 instruments. It comes with a 30 ft (10 m) cable. This transducer reads depth only. It does not include speed or temperature, and it is not a Chirp unit. The maker lists it for metal, wood and fiberglass hulls.
Our take
The 30 ft (10 m) cable on this transom mount transducer limits how far the ST40 display can sit from the stern. It reads depth only, with no speed, temperature or Chirp, so it is a plain depth sensor for ST40 instruments.
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.
