{"product_id":"garmin-airmar-r109m-transducer-010-12809-20","title":"Garmin Airmar R109M Transducer","description":"The Garmin R109LM is a high-power CHIRP thru-hull transducer that pairs a low band of 38 to 75 kHz with a medium band of 80 to 130 kHz, giving 87 kHz of total bandwidth from one 16-element broadband ceramic array. The medium channel sits between low and high frequency operation, sounding deeper than a high-frequency transducer while returning better resolution and a wider beam than the low band alone.\n\nWith 2 kW of transmit power the low band sounds to 6,000 ft and the medium band to 3,000 ft. The narrow low beam and the medium beam combine deep-water reach with broad coverage beneath the boat. The urethane housing installs as an external thru-hull with a High-Performance Fairing and suits fibreglass, wood or metal hulls up to 22 degrees deadrise on vessels of 12 m and above. An integral depth and fast-response temperature sensor is included. 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":55951016722772,"sku":"010-12809-20","price":3502.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/legacy-c2c61307.gif?v=1781903250","url":"https:\/\/hudsonmarine.co.uk\/products\/garmin-airmar-r109m-transducer-010-12809-20","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
