It can read depths to 100 m (330 ft) and offers fast 5 Hz water speed signal output for smoother visualisation on compatible chartplotters or other displays.\u003c\/p\u003e\n\u003cp id=\"FNUY5Y9\"\u003eWireless Bluetooth connectivity makes it easy to manage calibration of sensor data through the AIRMAR Cast app interface. And the 235 kHz sensor operating frequency helps prevent mutual interference with other echosounder devices on the vessel. The transducer’s wide, fan-shaped beamwidth of 10 x 44 degrees enables it to find bottom even when installed on steep deadrise hulls or heeling sailboats.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTransducer frequency: 235 kHz\u003c\/li\u003e\n\u003cli\u003eTransducer power: 100W\u003c\/li\u003e\n\u003cli\u003eTransducer beamwidth: 100 x 44 degrees\u003c\/li\u003e\n\u003cli\u003eTransducer maximum depth: 330ft\u003c\/li\u003e\n\u003cli\u003eTransducer Measures: Depth, Temperature and Speed\u003c\/li\u003e\n\u003cli\u003eTransducer number of pins: NMEA 2000\u003c\/li\u003e\n\u003cli\u003eTransducer supported deadrise\/transom angles: 0 to 22 degrees\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Garmin Airmar DST820 Smart Thru-Hull Transducer directly replaces the discontinued Garmin Airmar DST810.\u003c\/p\u003e\n\u003cp\u003eKey Details of the Replacement\u003c\/p\u003e\n\u003cp\u003e• Compatibility: The Garmin Airmar DST820 fits the exact same 2-inch thru-hull fitting as the DST810, meaning you can swap the insert out without doing any new hull work or cutting.\u003cbr\u003e• Core Functions: It continues to provide depth, speed-through-water, water temperature, and integrated vessel attitude data (heel, trim, pitch, and roll) over the NMEA 2000 network with Bluetooth connectivity for the Airmar CAST app.\u003cbr\u003e• Upgrades: It features improvements like an updated Gen2 paddlewheel for better low-speed linearity and a slightly faster refresh rate.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":63874685469002,"sku":"SM230-0101105130","price":365.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0855\/5125\/1786\/files\/230-0101105130_1.jpg?v=1791629910","url":"https:\/\/seamarknunn.com\/products\/garmin-airmar-dst820-depth-speed-temp-thru-hull-smart-transducer","provider":"Seamark Nunn","version":"1.0","type":"link"}
