FIFISH V6 PLUS

150 m inspection ROV with distance and altitude sensing, laser scaling and 4K imaging.

V6 PLUS combines Q-Motor stabilization with a forward distance sensor and downward altitude sensor. These support distance lock, altitude lock and obstacle avoidance during close inspection. Its laser scaler and FIFISH APP support visual measurement; optional U-QPS adds underwater position data.

Configuration options

V6 PLUS inspection systemStandard platform

Vehicle with distance/altitude sensing, laser scaler, 200 m tether and transport case.

Extended mission equipmentOptional

Onshore power and U-QPS positioning are optional. Select compatible tools through the V6 PLUS configuration; store V6 EXPERT connectors are not automatically interchangeable.

Compatibility and naming

Tool ratings do not increase the vehicle depth rating. Select the connector, mounting kit and hardware revision for this ROV; optional equipment is configured separately.

Performance notes

Endurance, current holding and charging figures depend on the task, payload, water conditions and temperature. Tether length and rated diving depth are different limits; the complete configured system must suit the mission.
