Combining a 400 kHz \/ 550 kHz sonar, high-precision INS-based motion stabilization, GNSS positioning, and surface sound velocity sensing in one compact unit, it delivers dependable underwater mapping from inland lakes and rivers to coastal and offshore environments.\u003c\/p\u003e\n\u003cp\u003eWith \u003cstrong\u003e512 receive beams\u003c\/strong\u003e, a \u003cstrong\u003e145° swath coverage\u003c\/strong\u003e (up to 6 times water depth), and \u003cstrong\u003e0.03° roll and pitch accuracy\u003c\/strong\u003e, the HN-400M captures dense, full-coverage bathymetric data even where turbidity, depth variation, and vessel motion would compromise conventional systems. Its \u003cstrong\u003e400 kHz FM chirp\u003c\/strong\u003e mode penetrates deep and turbid water down to \u003cstrong\u003e200 m\u003c\/strong\u003e, while the \u003cstrong\u003e550 kHz\u003c\/strong\u003e mode resolves fine detail for precision shallow-water work — one system for every environment.\u003c\/p\u003e\n\u003cp\u003eBuilt for real-world deployment, the system weighs just \u003cstrong\u003e3.5 kg\u003c\/strong\u003e, installs \u003cstrong\u003ecalibration-free\u003c\/strong\u003e, and mounts in minutes on \u003cstrong\u003eUSVs such as the APACHE 4, APACHE 4 Pro, and APACHE 6\u003c\/strong\u003e, or on manned vessels via a mounting bracket. The \u003cstrong\u003eEasySail Android app\u003c\/strong\u003e puts vessel control, acquisition, parameter setup, and real-time 3D preview in one touch — no field computer required.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose the CHCNAV HN-400M?\u003c\/h3\u003e\n\u003cp\u003eThe HN-400M stands out as a \u003cstrong\u003esmarter, more adaptable multibeam solution for professionals surveying difficult waters.\u003c\/strong\u003e Intelligent dual-frequency operation, an integrated 0.03° IMU, and roll-stabilized beam steering keep data quality high in waves up to 1 m on USV platforms. Setup that traditionally takes 3 hours is done in 30 minutes, and a complete survey can be run by a two-person crew.\u003c\/p\u003e\n\u003cp\u003eUpgrade your hydrographic capability with the CHCNAV HN-400M and cover more water, in more conditions, with cleaner deliverables and faster mobilization.\u003c\/p\u003e","brand":"CHCNAV","offers":[{"title":"Default Title","offer_id":44536957337651,"sku":null,"price":20000.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/4888\/8371\/files\/HN-400M_Sonar_Deck_Unit.jpg?v=1784140221","url":"https:\/\/latnet.ca\/products\/chcnav-hn-400m-multi-beam-echosounder","provider":"Latnet Technologies","version":"1.0","type":"link"}
