Fifish V-Evo
The first consumer-grade underwater robot to combine a 4K 60fps camera with 360° omni-directional mobility. Equipped with AI Vision Lock technology to lock focus on objects even in moving water currents.
- Visuals: Ultra-smooth 4K 60fps footage with a 166° ultra-wide lens.
- Mobility: Freely moves in all directions (lateral, pitch, roll).
- Lighting: 5000-lumen LED light for clarity in dark depths.
- Intelligence: AI features to remove water haze in real-time.
Fifish E-Master
The Enterprise Series is designed for underwater infrastructure inspection. The E-Master features a modular design that allows for the simultaneous installation of various add-ons to support complex professional missions.
- Modularity: Supports the integration of sonar sensors, robotic arms, and thickness gauges.
- Stability: An enhanced stabilization system to withstand stronger water currents.
- Efficiency: A body structure that is easy to disassemble and reassemble for quick maintenance.
- Durability: A corrosion-resistant body material for long-term use at sea.
Fifish X1
A heavy-duty ROV designed for high thrust and the ability to carry a large sensor payload. The X1 is a reliable workhorse solution for the energy industry, marine research, and SAR teams requiring stable performance at great depths.
- Power: Industrial-grade propulsion motors designed to withstand strong currents.
- Capacity: Capable of carrying heavy sensor payloads such as multibeam sonar.
- Durability: Higher operational depth compared to the V or E series.
- Integration: Precision control systems for navigation in critical structural areas.

Industry Applications
Aquaculture & Fisheries
The QYSEA ROV is used as a smart monitoring tool for modern fish farms (marine ponds). This robot assists with net inspections, monitors water quality, assesses the health of fish stocks, and even cleans up waste and fish carcasses from the pond bottom without the need to deploy human divers.
- Specialized AI Technology: Equipped with AI Fish Counting (automatic fish population counting) and AI Fish Net Inspections (automatic detection of net tears).
- Direct Intervention Tools: Can be fitted with a Net Repair Kit and a robotic arm to retrieve dead fish to prevent the spread of disease.
Search & Rescue / SAR
In emergency situations such as drowning victims or vehicles that have fallen into the water, the FIFISH series provides fast and safe underwater visual support for SAR teams, police, and law enforcement.
- Vision in Turbid Water: Uses 2D Imaging Sonar and AI Image Enhancement algorithms to “see” objects in extremely turbid or pitch-black water.
- Super-Fast Response (Swift Deployment): Highly portable, requiring only 3–5 minutes to set up and deploy into the water.
- Diver Tracking (AI Diver Tracking): Can automatically lock onto and track the movements of SAR divers to ensure their safety.
Infrastructure & Water Management
An efficient solution for evaluating the structural integrity of public water infrastructure such as dams, reservoirs, bridges, ports, and confined spaces such as giant culverts.
- Underwater Topographic Mapping (Bathymetric Mapping): Capable of automatically scanning and profiling reservoir bottoms (to identify sedimentation/siltation).
- Autopilot Navigation (U-INS): Supports 3D path planning to automatically perform routine inspections along the same dam route.
Offshore Energy: Oil, Gas & Wind
Used for inspecting critical offshore assets, such as offshore wind turbine foundations, subsea oil pipelines, and drilling platforms.
- Strong Current Resistance: Equipped with a Station Lock Hovering feature (using a Q-DVL sensor) that allows the robot to remain stationary at a single point even when subjected to ocean currents of up to 3–4 knots.
- Non-Stop 24/7 Operation: Features a Direct Power Supply System (direct power cable from the vessel), eliminating reliance on battery capacity.
- Precision Measurement: The AR Ruler & Laser Scaler modules enable measurement of cracks or pipe damage with accuracy up to ±1 cm.
Maritime & Shipping
Helps shipping companies quickly inspect ship hulls, propellers, and ballast tanks without having to put the ship in dry dock.
- Non-Destructive Testing (NDT): Supports specialized payloads such as ultrasonic thickness gauges (UTG) and anode inspections.
- Ultra-Wide-Angle Camera: A 166° FOV lens combined with a light output of up to 12,000 lumens captures micro-damage or barnacle buildup on the ship’s hull with exceptional clarity.
The Difference with QYSEA
True Omnidirectional
It can perform roll, pitch, and yaw movements freely.
AI Vision & Posture Lock
Can lock the drone’s tilt angle.
A Flexible Modular Ecosystem
Installing accessories is easier and plug-and-play.
FAQ
No. All professional ROVs, including the QYSEA FIFISH, use a cable (called a tether) to connect the drone to the controller on the surface. This cable is essential for transmitting stable HD video and control signals through the water (radio waves and Wi-Fi do not transmit well through water).
It depends on the model. The standard series (such as the V6) is typically capable of diving to a depth of 100 meters. The industrial series (such as the W6 or V6 Plus) can reach depths of 150 to 350 meters.
Drone tidak akan tenggelam ke dasar laut, tetapi akan mengapung perlahan atau melayang (tergantung pengaturan pemberat). Anda cukup menarik kabel tether secara manual untuk membawa drone kembali ke permukaan.
Yes. This is one of QYSEA’s standout features. This drone features omnidirectional technology, meaning it can move freely in all directions (rolling, tilting down, tilting up, and sideways) and can lock into that position (Posture Lock) while continuing to move forward.
Of course. The drone’s camera transmits a real-time video feed to your phone, tablet, or controller via a tether cable. The quality is very clear (usually 720p or 1080p for the live view).
The FIFISH camera records at up to 4K UHD resolution and is equipped with two extremely bright LED lights (4,000–6,000 lumens) to illuminate dark areas underwater. Its sensor is also specially designed to capture true-to-life underwater colors.
Yes, especially for the Expert and Pro series. The drone features a port interface that allows you to attach a robotic arm for gripping objects, a water sampling device, sonar, or a metal thickness gauge.
It is very safe. The drone’s motors and body are designed to be corrosion-resistant. However, it is essential to rinse the drone and its motors with clean fresh water after every use in the ocean to prevent salt crystal buildup.
The average dive duration is 3 to 4 hours under normal use. Some industrial models support an onshore power supply system for unlimited, non-stop operation.
It’s relatively easy, especially if you’re familiar with drones or video games. QYSEA also offers a motion-sensing control mode (VR Head Tracking), where the drone will turn to follow your head movements while you’re wearing VR goggles.
