Navico EP-80R Temperature Sensor - NMEA2000 - Transom Mount

Enhance your boating experience with precise temperature monitoring across your vessel using the EP-80R Temperature Sensor. This NMEA 2000-compatible device seamlessly connects to your marine network, delivering real-time data to your multifunction display (MFD). Whether you're tracking water temperatures for optimal fishing spots, keeping tabs on live wells to ensure bait stays lively, or monitoring engine room conditions to prevent overheating, this sensor provides reliable insights that help you make smarter decisions on the water.

Why Anglers and Boaters Rely on This Temperature Sensor

Fishermen know that water temperature plays a crucial role in fish behavior—species like bass or walleye often congregate around specific thermal layers. With this transom-mount sensor, you get accurate readings from 4°F to 176°F, displayed right alongside your charts, sonar, and GPS data. No more guessing; integrate it into your Lowrance setup for a unified dashboard that elevates your on-water performance. Its rugged black housing withstands harsh marine environments, ensuring longevity even in rough seas or constant exposure to saltwater.

Versatile Configuration for Multiple Applications

Pre-configured for water temperature right out of the box, the EP-80R replaces the older EP-80 model and offers flexibility through reconfiguration on compatible Navico MFDs. Customize it for:

• Outside water conditions to spot thermoclines
• Inside cabin comfort
• Engine room alerts for maintenance
• Live well or bait well to protect your catch
• Cabin temperatures
• Refrigeration units
• Heating systems

Surface-mount design allows installation on transoms, hulls, or inside compartments like wells, ducts, or bulkheads—wherever you need data most.

Seamless NMEA 2000 Integration

Plug-and-play simplicity defines this sensor. It features a 5-pin wired connection and includes an NMEA 2000 T-connector for quick backbone integration without disrupting your existing network. Once connected, your MFD recognizes it instantly, letting you overlay temperature data on maps or set custom alarms for sudden changes—perfect for tournament anglers chasing striper schools or weekend warriors exploring new waters.

Built for Real-World Demands

Lowrance's reputation for durable marine electronics shines here. The sensor's robust construction handles vibrations, splashes, and temperature swings, backed by a commitment to quality that serious boaters trust. Easy setup means more time fishing and less fiddling with gear, while its single-unit design keeps your setup clean and efficient.

Practical Tips for Maximum Value

Position the sensor probe in flowing water for the most accurate external readings, or shield it in live wells to avoid false spikes from aeration. Pair it with other NMEA 2000 sensors like depth or speed for a comprehensive environmental picture. Regular network checks ensure peak performance, helping you stay ahead of the competition or simply enjoy safer, more informed outings.
