Whether you call them underwater drones or small ROVs, high-end micro ROVs are certainly gaining in popularity. Qysea’s impressive Fifish V-EVO is one of the latest and greatest gear.
Like nearly all underwater drones, the V-EVO is connected to its operator at the surface via a communications tether.Using a connected handheld controller arrive With the tether, users can pass commands to the drone through an app on their smartphone while watching live video from the drone’s cameras.
In the case of the V-EVO, the tether is 100 meters (328 feet) long — the drone’s maximum submersion depth — plus the camera has a 166-degree wide-angle lens and a maximum resolution of 4K/60fps.
The camera is aided by two forward facing 5,000 lumen 5,500K LED spotlights in dark, deep water. AI-based image enhancement software also helps the camera by digitally filtering out plankton and other suspended particles. Footage is recorded to the onboard 64GB memory card.

Thanks to its six thrusters, the V-EVO is capable of a full 360-degree movement.
This means that not only can it turn side to side and move up and down, but it can also rotate in place to move in any direction as needed. Using the app, users can also have it do things like automatically move to keep a selected subject centered in the shot, physically move onto a subject, or maintain its current orientation against underwater currents.
If the user wants to do more than just look In the underwater world, they can attach additional remote-controlled peripherals to ports on the bottom of the drone, such as grabbing arms, recovery hooks, or net repair kits.

Among other specifications, the 4.1 kg (9 lb) V-EVO has a top forward speed of 3 knots (5.6 km/h or 3.5 mph) and is capable of operating in water temperatures from -10 to 60 ºC (14 to 140 ºF), it’s claimed to run at full speed for an hour per charge — and up to four hours if it’s just hovering in one position.
