FIFISH V-EVO

FIFISH V-EVO is a tethered underwater vehicle designed primarily for filming, observation and light inspection. Six-thruster freedom lets the operator translate, rotate and hold different viewing angles, while vision-lock functions can keep a selected subject centred. An accessory port accepts optional tools such as a small gripper or metal detector, but those attachments are separate from the standard imaging package.

The camera records 4K video at up to 60 frames per second and has a 166-degree field of view above water; QYSEA specifies 96 degrees underwater. Twin lights provide a combined 5,000 lumens. The 3.9-kilogram vehicle is rated to 100 metres, reaches three knots and runs for one to four hours depending on movement and conditions. Current, visibility, tether handling, lighting, battery use and operator technique shape real performance.
