class=\"v5-faq\"><summary>Which DJI drones can I mount the ECT 400S on?<\/summary><div class=\"v5-faq-body\">The ECT 400S is compatible with DJI M210 (with lightweight housing), M300 RTK, M350 RTK and M600 Pro. The SkyHub system is required for the interface and data management.<\/div><\/details><details class=\"v5-faq\"><summary>What is the difference between standard and reinforced housing?<\/summary><div class=\"v5-faq-body\">The standard housing weighs 1.6kg total and is suitable for normal conditions. The reinforced housing (2.6kg) provides additional protection for operations in challenging marine conditions.<\/div><\/details><details class=\"v5-faq\"><summary>Can I use the ECT 400S without the SkyHub system?<\/summary><div class=\"v5-faq-body\">No, the ECT 400S necessarily requires the SkyHub system for the RS232 interface, data management and integration with the UgCS control software.<\/div><\/details><details class=\"v5-faq\"><summary>What precision can I achieve with this echo sounder?<\/summary><div class=\"v5-faq-body\">The ECT 400S provides millimetre-level precision thanks to integrated inclination and temperature sensors that automatically compensate for environmental variations during the survey.<\/div><\/details><details class=\"v5-faq\"><summary>Can the sensor penetrate through sediments?<\/summary><div class=\"v5-faq-body\">Yes, the 450 kHz frequency allows penetration through soft sediments to detect hard bottom classification, ideal for sedimentological studies.<\/div><\/details><details class=\"v5-faq\"><summary>What software is needed to process the data?<\/summary><div class=\"v5-faq-body\">The GUI software for real-time visualisation is included. For advanced processing it integrates with UgCS and other photogrammetry software to create 3D seabed models.<\/div><\/details><\/div><\/div><div class=\"v5-cta\"><span class=\"v5-cta-title\">Buy EchoLogger ECT 400S from DroneBase<\/span><p class=\"v5-cta-sub\">Pre and post-sales support \u00b7 Express 24h shipping \u00b7 Certified technical support \u00b7 On-site demo<\/p><span class=\"v5-badge\">\u2605 DJI Gold 5 Dealer<\/span><span class=\"v5-badge\">ISO 9001:2015<\/span><span class=\"v5-badge\">Technical support<\/span><span class=\"v5-badge\">On-site demo<\/span><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Ultracompact echo sounder at 450kHz for precision bathymetric surveys, with integrated transducer and inclination sensor for professional underwater mapping.
