Garmin Transom Mount Intelliducer with NMEA 2000 – Depth, Speed, and Water Temperature Sensor

Knowing what lies beneath your boat is critical for safe navigation, efficient fishing, and protecting your investment. Without reliable depth and water temperature data, you risk running aground, missing fish-holding structure, or drifting into hazardous conditions. The Garmin Transom Mount Intelliducer with NMEA 2000 eliminates guesswork by delivering precise, real-time sonar data directly to your compatible chartplotter or multifunction display.

Who is it for

This transducer is ideal for boat owners who want to upgrade their onboard sensor suite without complex through-hull installation. Whether you pilot a fiberglass runabout, an aluminum fishing boat, or a wooden classic, the transom mount design offers a straightforward, secure attachment to the stern. It suits anglers seeking accurate depth and water temperature readings, as well as cruisers who need reliable speed-over-water data for navigation and performance monitoring.

Main features

• Combines depth, speed, and water temperature sensing in one compact, streamlined unit.
• Connects directly to your NMEA 2000 network, simplifying wiring and data sharing with other compatible devices.
• Rated to a depth of 330 feet (100 meters), suitable for inland lakes, coastal waters, and offshore fishing.
• Measures speed over water from 0 to 50 knots (0-92 km/h), giving you accurate performance data.
• Water temperature range from 14°F to 104°F (-10°C to 40°C) covers a wide variety of aquatic environments.
• Includes a 20-foot (6-meter) NMEA 2000 drop cable and all necessary mounting hardware.

Tips

For optimal performance, mount the transducer on the starboard side of the transom where water flow is smoothest. Ensure the bottom of the transducer protrudes slightly below the hull and is parallel to the waterline. Check your chartplotter's NMEA 2000 compatibility before installation.
