300m intelligent underwater inspection & work expert

Stable, Anti Current, Strong Power & Superior Battery Life


Full Functioning Robotic Arm 

Supplied with a robotic arm the W6 can perform underwater retrieval as the arm can grab objects and features a clamp lock function.  The full functioning robotic arm can drag, drop, tow and salvage underwater objects up to around 20kG. The robotic arm is neutrally buoyant and easily detaches to be used without or swapped for another accessory.


FIFISH PRO W6 is an industrial grade underwater ROV platform with a depth rating of 300m & a 5 Q-interface for payload integration.

The FIFISH PRO W6 is equipped with the new patented 6 Q motor system,  additional battery capacity, and is more powerful for increased stable flight-current performance.  The innovative modular interface enables  rapid replacement of parts and the switching of accessories with various functions efficiently and precisely.

Dual 4K Camera System, Dual Camera Work Co-ordination

W6 4K ultra high definition dual camera system provides a wider field of view, realises the co-ordination of operation monitoring and motion observation and provides the user with a complete picture of the surrounding environment.  Comprehensive inspections can be performed and in addition with FIFISH patented software it can collect various information and analyse corresponding data to output work reports.

5 Q-Interface for Payload Integration 

FIFISH PRO W6 is a ROV platform which can be customised for various industrial specific applications. With 5 x integrated Q-interfaces for payload integration developers can easily develop their own dedicated accessory and expand the applications of the ROV to their field of expertise.

SONAR ARRAY SYSTEM – Distance Lock, Altitude Lock Sonar System

The Distance Lock, Altitude Lock and collision avoidance sonar system measures the forward distance and the downward altitude in real time.

Through Distance Lock and Altitude Lock, the difficulty of operation is reduced,  inspections and underwater tool usage is more efficient and accurate.

Multi-Tool Extensions, Unlimited Possibilities

The Q-IF (QYSEA Interface) enables FIFISH W6 to attach a variety of optional accessories for various applications and multiple tasks. 

Fifish accessories such as 2D/3D Imaging Sonar is available for inspection under dark and turbid water environments, Station Lock module enables a total locked position without drift so that the W6 can execute intricate operations.  Water Samplers, Fishing Net etc a full range is available.

If a custom accessory is required the W6 features 5 x integrate Q-interfaces for payload integration.  Developer can easily develop their own dedicated accessory and expand the applications of the ROV to their field of expertise.

High Precision Ruler Combination
(Laser Ruler + AR Ruler + Compass Ruler)

With this combination the W6 can accurately measure underwater objects. For example when inspecting a vessel it can accurately measure the scale of any cracks and hull damage effectively to identify and prevent any further damage.  When combined with the compass ruler it can accurately be adjusted and locked to the small objects for total accurate real time measurement.

Removeable Battery
The 388WH battery can operate for long periods (up to 6hrs).  The removeable battery can quickly and easily be replaced and supports quick charging mode and can be charged 70% in one hour.

300M Depth Rating
With a maximum depth of 300m the FIFISH PRO W6 is the top of it’s class for deep sea diving and operations.

12,000 Lumen Lights
Featuring 2 x 6000 Lumen LED headlights with different levels of brightness,  the W6 is the brightest in its class and can be used and easily see scenarios in low visibility or at night.

Removable SD Card
Quickly store and transfer data with the supplied 128mb SD card. The FIFISH W6 can support up to 512mb SD card.
