Garmin OnDeck Temperature Sensor

The Garmin OnDeck Temperature Sensor is a wireless monitoring solution designed for mariners, fishermen, and recreational boaters who demand real-time environmental data at their fingertips. This dedicated temperature sensor pairs seamlessly with the Garmin OnDeck Hub ecosystem, enabling remote temperature monitoring from the helm, cabin, or anywhere within wireless range.

Whether tracking water temperature for optimal fishing conditions, monitoring engine compartment heat, or observing cabin climate control, this sensor delivers reliable data across an exceptionally wide operating range. The sensor operates across a temperature range of −50° to 105°C (−58° to 221°F), making it suitable for diverse marine and tactical applications where extreme environmental conditions are commonplace. Its compact, rugged design withstands saltwater exposure and harsh deck environments typical of professional and recreational watercraft.

The Garmin OnDeck Temperature Sensor transmits data wirelessly to the OnDeck Hub, eliminating the need for complex wiring runs through bulkheads or structural penetrations, while maintaining consistent accuracy across its full operational spectrum. Boaters integrating Garmin marine electronics benefit from consolidated data display, reducing instrument panel clutter and simplifying situational awareness. This sensor is ideal for vessel owners running Garmin OnDeck systems, offering seamless integration with existing chartplotters and digital dashboards.
