{"product_id":"chcnav-d60-dual-frequency-echo-sounder","title":"CHCNAV D60 Dual Frequency Echo Sounder","description":"\u003cp dir=\"ltr\"\u003e\u003cspan\u003eLaunched April 2026, the CHCNAV D60 is an integrated dual-frequency echo sounder engineered for USV bathymetric operations. Operating at both 200 kHz and 33 kHz simultaneously, it covers a measurement range from 0.2 metres to 1,000 metres — handling shallow-water estuarial work and deep-water profiling from the same instrument. Integrated attitude and temperature sensors provide real-time compensation for vessel motion and sound velocity variation, while adaptive algorithms automatically adjust system parameters within 0.2 seconds — maintaining consistent data quality in turbid water, areas with rapid depth transitions and challenging survey conditions without manual intervention. At 1.2 kg with quick installation and removal, it is designed to minimise payload impact on compact USV platforms. \u003c\/span\u003e\u003c\/p\u003e","brand":"CHCNAV","offers":[{"title":"Default Title","offer_id":54985085813065,"sku":null,"price":1.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1022\/7482\/6569\/files\/D601.webp?v=1786460123","url":"https:\/\/surveyequipment.uk\/products\/chcnav-d60-dual-frequency-echo-sounder","provider":"Tri-Site Survey Equipment","version":"1.0","type":"link"}
