Open-sea maritime ROV with precise U-INS navigation, downward DVL station lock, and a Dual 4K camera system. 388.8 Wh battery for extended runs. Auto-navigation and path planning for repeat survey tasks.
FIFISH E‑GO
Modular industrial ROV with ring-wing propulsion and biomimetic caudal fin for quiet, stable movement. Hot-swappable twin-battery power and easy-to-detach modules keep the unit running across full operational days.
FIFISH V6 Expert
The flexible utility workhorse — 4.6 kg, single-person portable, and compatible with 20+ professional tools (grippers, laser scaler, sonar, sample bottles). QYSEA’s best-selling observation-class ROV for general-purpose inspection.
FIFISH V6 Plus
Power, depth and precision combined. 150 m depth, DVL station-lock hovering, strong stability in current and enhanced tool compatibility. The bridge between observation and inspection class for serious shallow subsea work.
FIFISH V‑EVO
The intelligent dive companion. 4K·60fps capture, 360° omnidirectional movement, and AI Vision Lock that keeps subjects in frame automatically. Diver tracking mode & imaging dehazing. Small enough to fly in as carry-on.

The hardware on
the hardware.
The difference between “an underwater camera” and a mission-ready inspection rig. xBoom integrates QYSEA’s full payload ecosystem, matched to your SOP.
Dual Q‑DVL station lock
Forward + downward Doppler velocity log modules for centimetre-level station-keeping, even in 2–4 knot currents.
3-axis robotic arm
With interchangeable cutters and 15/20/40 cm clampers. Six DOF of movement plus three arm axes for confined-space tasks.
UT thickness gauge
Ultrasonic thickness measurement for pier piles, ship hulls and pipeline corrosion surveys. Class-reportable readings.
CP (cathodic protection) probe
Corrosion-potential measurement on wind-farm monopiles, jackets and subsea pipelines. Pairs with evidence-grade video.
Dual laser scaler
Two parallel 660 nm red lasers, 10 cm apart. Reference for AR measurements and accurate scaling of defects in imagery.

Multibeam and 2D imaging sonars for low-visibility operation — silt, algae blooms, night ops. Displayed alongside optical feed.
Altimeter / echosounder
Accurate altitude-off-seabed tracking from 0.3 m to 10 m. Enables bathymetric-style survey flight paths and safe bottom tracking.
Cavitation jet cleaner
In-water biofouling removal for pier piles, monopiles and hull plates. Continuous cleaning mission alongside inspection.
USBL transponder
Ultra-short baseline positioning with surface vessel — accurate, real-time ROV position relative to the ship for offshore ops.
Submarine cable monitor
Specialised cable-follow mode with magnetic & visual tracking, ideal for subsea power and fiber route inspections.
Sample grabber & bottles
Sediment and biological sampling for research, environmental monitoring and forensic recovery missions.
Evidence-chain recorder
Time-stamped, tamper-evident 4K recording pipeline for SAR, forensic and class-reportable inspections.
What FIFISH gets
done, underwater.
We don’t just supply drones — we scope the mission, pick the right model, add the sensors, and train the pilots. Four core application areas, each with a concrete pick.
Monopile, jacket & cable‑route inspection.
Dams, bridges, pipelines, ports.
Search, rescue, recovery, forensics.
Cage rounds, reef surveys, hull checks.
Selection to
deployment.
The ROV is one part of the stack. We integrate sensors, imaging systems, control software, and trained pilots into a mission-ready ecosystem.
Sensor & payload integration
Sonar, CTD, UT gauges, laser scalers, grabbers, custom manipulators — matched to mission brief, not a catalogue.
Real-time video & data systems
4K video telemetry, recording stacks and evidence-grade data pipelines for engineering reports, class audits and courts.
Control & navigation setup
Console configuration, tether management, station-keeping, mission-planning & auto-cruise routes. Ready on day one.
Deployment & training support
On-site launch training, pilot certification, SOP development, rapid spares, and ongoing field support from our India ops.
Mission first.
Platform second.
Most underwater jobs don’t match a product sheet. We scope the mission with your ops team, pick or modify the right ROV, add the sensors and manipulators the job actually needs, and stay with you through the dives.
How an engagement runs.
Typical custom configurations.
Low-visibility SAR configuration for a state police marine wing — forward-looking imaging sonar, strobe spotlight, evidence-marker, and a field-hardened laptop console.
Ultrasonic thickness gauge on the E-Master arm for a port authority — pier-pile corrosion survey with class-accepted evidence reports and repeat-survey route planning.
Tangle-resistant cage-inspection kit for an aquaculture farm. Daily net-integrity rounds and biomass counts, piped into the farm-management dashboard.
Full NDT skid — UT gauge, CP probe, cavitation jet cleaner and dual DVL — for monopile inspection campaigns on an Indian offshore wind project.
