The FIFISH E-MASTER is the flagship ROV in QYSEA’s professional-grade E-Series, engineered for demanding underwater inspection, exploration, and measurement tasks. Designed with a modular quick-assemble architecture, it allows field teams to easily replace key components—such as thrusters, lights, cameras, and batteries—without needing to return to base. This means less downtime and more adaptability for dynamic missions in offshore, industrial, and scientific environments.

At the heart of the E-MASTER is a hot-swappable dual-battery system, delivering up to 5 hours of continuous operation. Combined with a robust build rated for depths up to 200 meters, and a six-thruster vectored layout that enables true 360° omnidirectional control, the system is capable of handling complex tasks in high-current conditions with stability and precision.

The ROV also comes equipped with advanced AI-powered capabilities, including posture and heading lock, real-time stabilization, object tracking, and precision measurement tools. These features make it ideal for professionals conducting structural inspections, aquaculture monitoring, marine research, or deepwater exploration.

To meet a range of mission profiles, the E-MASTER is available in multiple configurations. Each variant offers tailored tools and navigation systems based on operational needs—from standard inspections to advanced station-locking and bathymetric survey missions.

• E-MASTER Standard is perfect for general underwater inspections and data capture. It offers full maneuverability, a 4K UHD camera, and modular expandability—ideal for users who want a solid foundation with optional upgrades later.

• E-MASTER Plus builds on the Standard by including advanced 3D scanning and laser modules out of the box, making it ideal for detailed structural inspections, precise measurement tasks, and professional-grade visual mapping.

• E-Master Navi is the most advanced model, with integrated navigation and positioning sensors (USBL, DVL, IMU) for missions that require precise geolocation, automated path tracking, and real-time mapping—perfect for offshore, scientific, and industrial operations in zero-visibility or GNSS-denied environments.
