Submersible Inspection Drone
Dive beyond
the unknown.
FINDi FF2 is a compact underwater drone built for confined spaces — making
underwater inspections fully recordable, traceable, and repeatable, without a diver
in the water.
Why it wins
Built for confined spaces, proven at sea
-
Manhole-ready478 mm body fits standard sub-600 mm manholes for direct ground-level deployment.
-
Long enduranceUp to 9 hours per deployment at a 2.1 m/s (4-knot) top speed — stable in flowing water.
-
Holds position without GPSAn onboard acoustic Doppler sensor (DVL) gives station-holding and inertial navigation in confined spaces.
-
Data-driven, not just footagePosition, trajectory, annotations, and drawings stay linked from inspection through to the final report.
Where it works
Confined spaces, pipelines, and marine
Designed and tested in FINDi’s own underground test pool in Japan, the FF2 covers
liquid-phase pipelines, tanks, and culverts as readily as open marine work —
an upper payload deck of cameras and LED lights also handles surface structures
and hull inspections above the waterline it’s built to go under.
