This kit combines the GST 43 transducer with the GST 10 network adapter, enabling direct integration on an NMEA 2000 network or a legacy Nexus system. With a speed accuracy of ±1% and a capability of up to 90 knots (depending on the transducer type), this kit provides essential data for navigation and performance optimization, whether cruising or racing.\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and connectivity\u003c\/h3\u003e\n\u003cp\u003eThe GST 10 acts as a gateway between the GST 43 transducer and your onboard network. It connects to the NMEA 2000 network via a drop cable and a T-connector (included). The GST 43 can also be wired directly to a legacy Nexus network following the provided color code (green, yellow, white, shield). Once connected, the GST 10 appears as a device in the NMEA 2000 equipment list on Garmin, GMI, or GNX chartplotters. It supports essential PGNs: water speed (128259) and temperature (130312).\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and calibration\u003c\/h3\u003e\n\u003cp\u003eInstalling the GST 43 through-hull transducer requires a 43 mm hole in the hull. For sandwich hulls (cored fiberglass), specific preparation steps are required, including the use of resin or epoxy to seal the core. Temperature calibration is performed via the NMEA 2000 network menu on a Garmin chartplotter, GMI, or GNX. The GST 43 transducer comes with a transport cap, useful for cleaning or maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eComparison and positioning\u003c\/h3\u003e\n\u003cp\u003eCompared to the Garmin GST 20 transducer, which is limited to lower speeds and direct NMEA 2000 connectivity, the GST 43 + GST 10 offers superior speed capability (up to 90 knots) and increased integration flexibility thanks to the dedicated adapter. This kit is a cost-effective alternative to competing brands such as Airmar transducers, offering native compatibility with Garmin and Nexus networks. For sailors seeking a reliable and scalable speed and temperature measurement solution, this kit is an excellent value.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":53723877671252,"sku":"010-04284-00","price":158.56,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_0ffc759c-82ec-486d-9ffc-334a30abb151.png?v=1779186370","url":"https:\/\/skysat.fr\/en\/products\/garmin-gst-43-through-hull-transducer-gst-10","provider":"Skysat","version":"1.0","type":"link"}
