Underwater Drones

Underwater drones, also called ROVs, are tethered robots that stream 4K video from below the surface, so you can inspect, film, and recover without diving. Explore the FIFISH lineup: three modular ROVs built for professional inspection, aquatic monitoring, search and recovery, and underwater content creation.

FAQ

Frequently Asked Questions

Yes. A tethered underwater drone scouts structure, films fish and retrieves gear. Check local regulations first, since some waters restrict electronics.

A standard underwater fishing camera shows you one spot. A FIFISH drone swims to the fish, follows them and brings snagged lures back.

Often no. Fish tend to ignore a slow, quiet ROV, while sudden movement and bright light at close range can spook them, so approach gradually.

The onboard LEDs help in stained and shaded water. No camera sees through zero visibility.

Yes. Fit the Retrieval Hook and steer down to the snag, one recovered lure at a time pays the accessory off fast.

Range depends on your tether. The V-EVO ships with a 100m tether spool, which covers most fishing scenarios; check the product page for the rated depth.

Only if you will use the movement. An underwater camera for fishing that swims earns its price through scouting speed, footage and lure recovery. If you just watch one hole, buy adrop cam.

Yes. It packs small enough for a kayak, and as an underwater camera for ice fishing you steer it under the ice instead of watching one fixed cone.

PURCHASE & SUPPORT

No. The finder locates marks fast across open water; the drone confirms and films what they are. Run both.
