Garmin tempe™ External Wireless Temperature Sensor

The Garmin tempe External Wireless Temperature Sensor is a compact wireless device designed for serious anglers and boaters who demand real-time water and air temperature data at their fingertips. Whether you're chasing stripers in a tidal river, monitoring thermoclines while offshore fishing, or tracking conditions across multiple zones on a large cruising vessel, this external sensor pairs seamlessly with compatible Garmin marine electronics to deliver accurate temperature readings wirelessly.

This wireless sensor operates independently of cables or hardwired connections, transmitting temperature data to your Garmin chartplotter, fishfinder, or compatible multifunction display via a secure wireless protocol. The compact 3 × 3 × 7 inch form factor and lightweight design make installation straightforward on transducers, hull probes, or in-water mounting brackets without affecting boat balance or performance. The tempe sensor's robust design withstands saltwater and freshwater environments, delivering reliable readings that integrate directly into your navigation and fishing displays.

For anyone who understands that water temperature is the single most important variable in locating fish and optimizing performance, the tempe sensor removes guesswork and puts precision environmental data directly into your decision-making process. This allows you to overlay temperature data onto bathymetric charts and identify structural changes in the water column that concentrate fish, making it an essential tool for any serious angler or boater.
