Depth, Speed, and Temperature — All from One Transom-Mount Transducer
This Garmin plastic transom-mount transducer measures water depth, boat speed, and water temperature simultaneously, feeding all three data streams to your compatible Garmin fishfinder or chartplotter. It's a straightforward, reliable sensor package for boaters who want complete on-water data without multiple hull penetrations or separate sensors.
What It Measures
- Depth — Continuous bottom depth readings displayed on your compatible Garmin unit
- Speed — Paddlewheel-based water speed measurement for accurate speed-over-water data
- Temperature — Real-time surface water temperature readings
Construction & Mounting
- Plastic Housing — Lightweight, corrosion-resistant plastic construction suited for freshwater and inshore saltwater use
- Transom Mount — Mounts to the transom of most boat hull types; no through-hull installation required
Parts Desk Insights
Best Use Case: This transducer is the right choice for boaters who want depth, speed, and temperature data from a single unit without the complexity of a through-hull installation. It's particularly well-suited for aluminum fishing boats, bass boats, and smaller fiberglass hulls where a transom mount is the preferred installation method. The paddlewheel speed sensor provides accurate speed-over-water readings, making it a good fit for anglers who troll and need precise speed control, or for boaters who want to log water temperature for fishing pattern analysis.
Compatibility Note: Verify connector type and pin count against your Garmin unit before ordering. This transducer is designed for Garmin fishfinders and chartplotters with a compatible sonar port. If your unit uses a different connector format, see our transducer adapter cables and accessories for connection options.
Maintenance Note: The paddlewheel speed sensor requires periodic cleaning to maintain accuracy — debris or growth on the wheel will affect speed readings.
