The affordable way into professional FIFISH imaging

The FIFISH V-EVO is QYSEA's most accessible underwater ROV — the entry point into the FIFISH range. It packs 4K imaging, AI-assisted tracking and full 360° control into a compact, backpack-sized body that a single person can carry, launch and recover without a crane or support vessel.

For light-commercial inspection, survey scouting, research and dive support, it puts genuinely capable underwater eyes within reach of teams and budgets that a full industrial ROV would over-serve.

  • 4K UHD at 60 FPS · 166° ultra-wide field of view
  • AI Vision Lock with four intelligent tracking modes
  • Adaptive AI plankton filtering for clearer turbid-water footage
  • 5,000-lumen LEDs at 5,500K — daylight-accurate colour at depth
  • 360° omnidirectional mobility · 3-knot speed · 2-knot flow resistance
  • Up to 4 hours hovering / 1 hour full-mobility dive time
  • Expandable with robotic arm, grippers, sonar, GPS and more
Where It Fits

A practical first ROV for real work

The V-EVO is the consumer-class FIFISH model — but in professional hands it earns its keep as a low-cost, fast-deploy platform for the jobs that don't need a full industrial system.

💼 Low Entry Cost

The most affordable FIFISH ROV — a sensible first platform for teams testing ROV-based inspection before scaling up.

🎒 Truly Portable

Backpack-sized and one-person deployable from a quay, RIB or shoreline — no crane, winch or support vessel.

👁️ Keeps Divers Dry

Scout, preview and document a site before anyone gets wet — useful for dive support and quick condition checks.

🎥 Documentation-Ready

4K 60 FPS footage with AI tracking and plankton filtering produces records clear enough for reports and review.

Imaging System

4K 60 FPS Imaging & 5,000-Lumen Lighting

Engineered for accurate colour and sharp detail in difficult underwater light — the V-EVO's optical system is the heart of its inspection and documentation value.

See more, in worse water, in finer detail

A 4K UHD camera shooting at 60 FPS captures smooth, detailed footage for documentation, inspection and film work, with real-time colour balance and dynamic noise reduction keeping subjects natural at depth. The 166° ultra-wide field of view takes in the full scale of a hull section, jetty pile or reef in a single frame.

AI Feature · QYSEA

AI Vision Lock — Intelligent Tracking

Vision Lock uses real-time visual AI to automatically track, centre and follow an underwater subject — freeing the pilot to focus on the mission instead of constant manual framing.

FIFISH V-EVO AI Vision Lock tracking a target on the app
Touch any subject on the app — the V-EVO holds it in frame automatically
Four Tracking Modes

Touch a target, let the ROV keep it framed

Vision Lock turns subject-following into a one-tap action. Four modes cover the common framing problems — locking, zooming, orbiting and switching targets — so even a single operator can capture stable, usable footage while piloting.

Mode 01
Touch Lock

Tap any subject and the V-EVO centres and holds it in frame as both ROV and subject move.

Mode 02
Station Zoom

Pinch-to-zoom physically moves the ROV closer or back — not a digital crop — for full-resolution detail.

Mode 03
Off-Centre Lock

Hold a fixed distance from a locked target while adjusting heading and angle — ideal for orbiting inspections.

Mode 04
Slide Lock

Swipe to switch focus between targets in the frame — useful for multi-subject monitoring.

Adaptive AI Sea Plankton Filtering

The V-EVO's on-board AI continuously analyses the video feed and suppresses the white marine flakes and suspended particles that ruin underwater footage — markedly improving image quality in coastal waters, estuaries and any environment with biological or sediment turbidity.

Engineering

Hydrodynamic Design & 360° Mobility

The V-EVO's waterproof body is shaped to move as naturally underwater as a marine animal — every curve reduces drag, every thruster contributes to full-sphere control.

Compact six-thruster body — shown here with the optional robotic arm
6 DOF · 360° Omnidirectional

Move in any direction, hold any angle

Full six-degrees-of-freedom control lets the V-EVO move forward/back, left/right and up/down while rotating on every axis — hovering on station, rolling for cinematic angles, or locking posture for a precise inspection view. The hydrodynamic shell minimises drag and the vibration that would otherwise blur footage.

2 knflow resistance
  • Station hovering — automatically holds position and depth with no constant pilot input
  • 360° roll & posture control — level, tilted or inverted for any camera angle
  • −10°C to 60°C operating range for cold-water and tropical work
  • VR immersive control — first-person piloting with compatible goggles (sold separately)

Real-World Deployment

One person. One backpack. In the water in minutes.

The compact body and complete one-case kit make the V-EVO deployable by a single operator from a quay, RIB or shoreline — ideal for fast site scouting, light inspection and dive support.

Where It Works

Built for Portable Inspection & Light Commercial Work

4K imaging, AI tracking and 100 m depth in a one-person package — the V-EVO covers the everyday underwater tasks that don't justify a full industrial ROV.

🏗️

Portable Inspection

Survey jetties, pontoons, harbour walls, boat hulls and marina structures to 100 m — paired with the robotic arm or hook for simple intervention.

🆘

Diver Support & Scouting

Scout conditions and points of interest before a dive, and give the surface team live video and a spotter view during operations.

🐟

Aquaculture Monitoring

Check nets, moorings and stock at fish farms with minimal disturbance — a low-cost daily-use eye underwater.

🔬

Research & Conservation

Document reef health, monitor habitats and collect visual data with no diver disturbance — widely used by universities and NGOs.

📚

Education & STEM

A classroom and field tool for marine-science and oceanography programmes — hands-on access to the underwater world.

🎬

Underwater Cinematography

4K 60 FPS footage, AI tracking and cinematic movement modes for documentary-quality footage without a crewed dive team.
