{"product_id":"garmin-airmar-509lh-chirp-dual-range-2-3kw-through-hull-transducer-010-11640-30","title":"Garmin Airmar 509LH CHIRP Dual Range 2-3kW Through Hull Transducer","description":"The Garmin 509LH (Airmar R509LH) is the highest-power thru-hull CHIRP transducer in the range, built around a 25-element broadband ceramic array. It sweeps a 28 to 60 kHz low band and a 130 to 210 kHz high band, giving 112 kHz of total bandwidth from one transducer. The CHIRP sweep delivers shallow-water-like target separation at extreme depths and at low frequencies.\n\nWith 2 to 3 kW of dual-range transmit power the 509LH sounds to 10,000 ft, with the high band returning fine detail to 1,500 ft. Its very narrow beam at both frequencies concentrates energy on the target for outstanding deep-water imaging. The epoxy housing installs as an external thru-hull with a High-Performance Fairing and suits fibreglass, wood or metal hulls up to 25 degrees deadrise on vessels of 12 m and above. An integral depth and fast-response temperature sensor is built in. The transducer terminates in bare wires and requires the Garmin GSD 26 CHIRP sonar module, which connects to networked GPSMAP chartplotters.","brand":"Garmin","offers":[{"title":"Default Title","offer_id":55952531751252,"sku":"010-11640-30","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/legacy-370bf0f6.jpg?v=1781902713","url":"https:\/\/hudsonmarine.co.uk\/products\/garmin-airmar-509lh-chirp-dual-range-2-3kw-through-hull-transducer-010-11640-30","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
