{"product_id":"garmin-sonde-gt8hw-tm-chirp-large-haute","title":"GT8HW-TM plastic depth sounder, for transom or electric motor mounting, CHIRP wide and high (150-240 kHz, 250 W) (8-pin)","description":"\u003cp\u003e\nDesigned for shallow-water fishing, the Garmin GT8HW-TM fishfinder is a plastic transducer optimized for transom or electric motor mounting. It features CHIRP wide and high sonar technology, operating in the 150–240 kHz frequency range with 250 W power output. This configuration delivers precise detection in freshwater up to 800 ft (approximately 244 m), providing clear bottom definition, distinct fish arches, and effective target separation with a beam angle reaching 24 degrees.\n\u003c\/p\u003e\n\u003ch3\u003ePositioning and Compatibility\u003c\/h3\u003e\n\u003cp\u003e\nThe GT8HW-TM fishfinder positions itself as a high-performance entry-level solution for freshwater anglers prioritizing image clarity and simplified installation. It differs from Garmin’s more advanced models, such as the GTxx series with ClearVü or SideVü technologies, by focusing exclusively on traditional CHIRP sonar. This approach ensures extended coverage and reliable fish detection within its power range, without the added complexity or cost of structural imaging features. The transducer is compatible with a range of Garmin devices, including STRIKER chartplotter\/fishfinders, echoMAP CHIRP, GPSMAP units, and the GSD25 sounder module. Its 6 m (20 ft) cable and 8-pin connector facilitate integration with existing systems.\n\u003c\/p\u003e\n\u003ch3\u003eInstallation and Performance\u003c\/h3\u003e\n\u003cp\u003e\nThe GT8HW-TM is designed for optimal performance at speeds below 34 mph (approximately 55 km\/h). Its transom or electric motor mounting is simplified with included brackets, though care is required to avoid interference from turbulence generated by the propeller or other hull elements. Installation instructions recommend mounting it as close to the boat’s center as possible, away from air bubbles and prop wash, ideally at least 38 cm (15 in) from the propeller for flat hulls. This transducer provides depth and water temperature data, essential for analyzing fishing conditions.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":56009370829140,"sku":"010-12401-00","price":137.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_ab82f985-82f6-4a5b-9ddd-539459f1fa98.jpg?v=1780437535","url":"https:\/\/skysat.fr\/en-us\/products\/garmin-gt8hw-tm-chirp-wide-high-depth-sounder","provider":"Skysat","version":"1.0","type":"link"}
