QYSEA FIFISH E-Master Series
Inquiry Form
The QYSEA FIFISH E-Master Series is an all-in-one industrial underwater ROV platform designed for advanced inspection, measurement, and survey missions in challenging subsea environments. Engineered for professional operators, engineers, and survey teams, E-Master combines high-speed ring-wing propulsion, AI stabilization systems, navigation sensors, precision measurement tools, and modular payload capability to deliver accurate data collection with efficient deployment.
The E-Master platform is available in three mission-ready configurations — E-GO Pro, E-Master Plus, and E-Master NAVI — enabling users to select the ideal setup depending on whether the requirement is high-mobility inspection, precision measurement, or fully integrated navigation-based surveying.
Across all models, the E-Master series features 146° ultra-wide 4K imaging, powerful 10,000-lumen lighting, station-lock hovering capability, six-degree-of-freedom omnidirectional control, hot-swappable battery systems, and expandable multi-tool payload ports. Advanced models introduce laser scaling, dual Q-DVL positioning, echo sounder bathymetry, and inertial navigation support for professional survey-grade measurement and mapping workflows.
Built to perform across port and hull inspections, reservoir surveys, bridge foundation scanning, environmental monitoring, and infrastructure asset assessment, the FIFISH E-Master system delivers precision, stability, and mission scalability in a single industrial-ready ROV platform.
