Garmin GST™ 43 Thru-Hull Speed/Temperature Transducer w/GST™ 10 Bundle

The Garmin GST™ 43 Thru-Hull Speed/Temperature Transducer w/GST™ 10 Bundle provides essential data for serious mariners who require precise surface water speed and temperature readings. Navigating heavy currents or tracking thermoclines for fishing success demands reliable sensors that interface seamlessly with modern onboard electronics. This bundle is designed for boaters looking to upgrade their existing hulls or install a high-performance monitoring system for better situational awareness. By converting analog data into a digital format, it ensures that critical environmental information is always accessible at the helm.

This thru-hull transducer utilizes a 43mm design that allows for efficient installation and accurate data collection directly through the vessel's hull. The included GST 10 digital gateway acts as the bridge, converting the analog speed and temperature signals into NMEA 2000 data for compatibility with Garmin chartplotters and networked displays. Its robust construction ensures longevity in harsh saltwater environments, while the precision paddlewheel mechanism provides responsive speed-through-water measurements. The system is engineered to minimize drag while maximizing sensor exposure to the water column for consistent performance at various speeds.

Owners of legacy equipment will find the Garmin GST™ 43 Thru-Hull Speed/Temperature Transducer w/GST™ 10 Bundle particularly useful as it can retrofit existing Nexus 43mm (TH43) thru-hull transducers. This compatibility simplifies the installation process for those moving to more modern NMEA 2000 networks without the need for extensive hull modifications or drilling new holes. Whether you are looking to buy a replacement sensor or upgrade a system, this bundle provides the necessary specifications for professional marine integration. It serves as a foundational component for any integrated marine electronics suite requiring high-fidelity environmental data.
