{"product_id":"garmin-gt15m-thf-010-02868-02","title":"Garmin GT15M-THF","description":"The Garmin GT15M-THF delivers powerful 600 W mid-band CHIRP traditional sonar from a clean flush thru-hull fitting, with a stainless steel housing suitable for fibreglass, wood, composite, aluminium and steel hulls. Operating across 85 to 165 kHz, it produces excellent target separation and clear bottom detail to 580 m (1,900 ft) in freshwater and 365 m (1,200 ft) in saltwater. This 20 degree version has the correcting angle built into the housing, so it flush-mounts on hulls with 17 to 24 degrees of deadrise without cutting a separate fairing block. For aluminium and steel hulls the included galvanic isolation components prevent corrosion. A 15 m (50 ft) cable terminates in an 8-pin connector that plugs into a compatible Garmin chartplotter, fishfinder or sonar black box, with Garmin auto-detection setting up the sonar and a water-temperature reading supported on compatible displays.","brand":"Garmin","offers":[{"title":"Default Title","offer_id":55951113716052,"sku":"010-02868-02","price":697.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/legacy-2f7922e3.png?v=1781903866","url":"https:\/\/hudsonmarine.co.uk\/products\/garmin-gt15m-thf-010-02868-02","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
