FIFISH E Series
Industrial ROVs —
Powered by Onboard AI.
The FIFISH E Series brings precision measurement, autonomous navigation and 3D mapping to commercial inspection. Two purpose-built platforms — the flagship E-MASTER and the portable E-GO — share the same Ring-Wing propulsion and FIFISH AI suite.
Built for Commercial Demands
The E Series goes beyond inspection to deliver autonomous operation, precision measurement and 3D mapping — all on one platform, all swappable in the field.
Q-DVL Station Lock
Doppler sonar keeps the ROV hovering precisely in place — even in mild currents — with collision avoidance and altitude hold.
QY-MT AI Measurement
AI-powered measurement with 99.7% accuracy. Measure dimensions, detect cracks and quantify defects without divers or callipers.
QY-BT Bathymetric Mapping
Generate 2D and 3D seafloor topographic maps directly from the ROV — no separate survey equipment required.
Hot-Swap Batteries
Dual swappable batteries and modular components keep operations continuous — swap, recharge and redeploy with zero downtime.
Choose Your E Series ROV
Both share the full FIFISH AI software suite and Ring-Wing propulsion. The E-MASTER reaches deeper with four AI modules; the E-GO is the portable, rapidly reconfigurable workhorse.

Flagship
FIFISH E-MASTER
QYSEA's flagship industrial ROV for complex inspection, measurement and survey. Ring-Wing propulsion, four integrated AI modules, dual hot-swap batteries and 10,000-lumen imaging — built for back-to-back commercial dive schedules to 200 m.
FIFISH E-GO
A portable industrial ROV in a compact, highly modular package — Ring-Wing propulsion, Q-STEADY stability, Q-DVL station-lock and QY-MT measurement with laser ruler. Rapid 9-second accessory swaps make it a versatile multi-tool from 100 m, with a 200 m option.

The Intelligence Behind the E Series
The E-MASTER and E-GO rely on QYSEA's own underwater AI — measurement, mapping, station-holding, diver tracking and vision lock — built into the ROV, not bolted on. Explore each capability.
QY-MT
99.7% accurate AI measurement with an AR virtual ruler and laser scaler — quantify cracks, corrosion and structures without a diver.
Explore QY-MT →QY-BT
Automated 2D/3D bathymetric mapping of seabeds, riverbeds, tank floors and reservoirs during a normal dive.
Explore QY-BT →Q-DVL
Forward & downward Doppler sonar for station-lock hovering, collision avoidance and altitude hold in current.
Explore Q-DVL →AI Diver Tracking
Onboard vision that identifies and follows a working diver, with AI dehazing for turbid water.
Explore AI Diver →Vision Lock & AI Platform
Vision-based target lock and stable hovering — the umbrella platform tying the FIFISH AI suite together.
