The Garmin AIRMAR® T80 Water Temperature Probe (8-pin) (010-10717-20) is a high-precision, heavy-duty transom-mount sensor designed to provide fast, highly accurate sea surface water temperature readings directly to compatible Garmin chartplotters and fishfinders. Built with a thermal response time optimized for detecting subtle water temperature boundaries—crucial for locate target fish species and monitoring environmental shifts—the sensor features a durable, impact-resistant plastic housing engineered to withstand high vessel speeds and harsh marine environments. Equipped with a standard Garmin 8-pin connector, the T80 integrates seamlessly into existing Garmin marine networks without the need for additional signal converters or junction boxes.
