Underwater Robot FiFish V6

The FiFish V6 is a mini-ROV sized vehicle that has all main features inherited from larger underwater systems. It has embedded batteries allowing for autonomy of 4.5 hours. It´s an entry level ROV for users who require a 4K/1080P underwater camera functionality on a limited budget.

It has a very small size, thin umbilical cable and very high maneuvering capability which allows operating in hard-to-reach places including inside sunken wrecks. With all directional freedom and portable design, FIFISH V6 has bring the revolutionary point of view (POV) for underwater photography and filmmaking

The V6 is a professional underwater robot that can dive up to a depth of 100 meters underwater to complete a variety of photographic and video graphic tasks. It is an efficient tool for diving, fishing, boating, yachting, sailing, and other ocean activities; the V6 can also be used as professional detection equipment for aquaculture industry, infrastructure inspection and other underwater observation tasks.

Affordable Multi-Task Underwater Drone

Many of the tasks assigned to work class ROVs – or human divers – is shallow (less than 300m) and involves searching, inspecting, or surveying underwater. These tasks are ideally suited to FiFish V6 mini ROV technology. Smaller, lighter, ROVs that consume very little power can be deployed from many different areas or rigs and ships. Since they have very little mass, they can be safely used on comparatively delicate machinery without fear of damage.
Launching simply involves heaving the submersible by hand into the water. They can be deployed in sea states that would be too dangerous for larger machines. Their thrust to weight ratio for a small tether means that mini ROVs can be handle more current than most work class ROVs in shallow waters.

Exquisite and User-Friendly Design

FiFish V6 is one of the smallest ROV in the market, with dimensions about 383x331x143mm. It’s easily to take everywhere in backpack or suitcase. The operate system is quite user-friendly, could easily be operated through remote control or APP.
Always ready for immediate deployment, the FiFish V6 underwater robot is portable, quick and easy to launch and intuitively piloted
