{"product_id":"garmin-gt30-th-through-hull-010-01961-10","title":"Garmin GT30-TH Through Hull 12 pin","description":"The Garmin GT30-TH is a 12-pin thru-hull transducer that delivers Garmin ClearVu and SideVu CHIRP scanning sonar at 455 and 800 kHz, optimised for clearer images at shallow depths. The 500 W elements give picture-like detail of structure and fish below the boat (ClearVu to 750 ft) and out to the sides (SideVu 250 ft each side, 500 ft total). A fairing block, isolation plate and bushings are included so it can be flush-mounted on hulls of 0 to 5 degrees deadrise and on metal hulls, and Garmin requires at least one anti-rotation bolt. A built-in fast-response water temperature sensor is fitted. It connects via a 12-pin sonar port to compatible Garmin chartplotters and the GCV 20 or GSD 25 sonar black box. For higher-deadrise hulls, the GT30-THP thru-hull pair extends SideVu coverage.","brand":"Garmin","offers":[{"title":"Default Title","offer_id":55952500982100,"sku":"010-01961-10","price":544.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/legacy-a349091c.jpg?v=1781902676","url":"https:\/\/hudsonmarine.co.uk\/products\/garmin-gt30-th-through-hull-010-01961-10","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
