Underwater Drones

“I use this product to capture beautiful videos of fish in Atlantic Canada. It’s helped me better understand fish and their behaviours while simultaneously inspiring others to get outdoors and catch fish and also protect them.”

“In New York there’s alot of bodies of water and a lot of history and unknowns. It’s all been stories so exploring underneath the surface and finding the evidence and the physical things to the stories. With Qysea, they’re the right drones if you need professional work done.”

FAQ

Frequently Asked Questions

An underwater drone is a tethered ROV that streams live video from below the surface, controlled from a phone or remote. FIFISH models let you inspect, film and recover without diving.

Yes. ‘Underwater ROV’ is the professional term while ‘underwater drone’ is the consumer term for the same tethered device.

Depth depends on the model and tether length. Longer tether spools (100m, 200m, 300m) extend reach. See each product page for associated ratings.

Yes. It's built to scout structure and fish behaviour in real time, complementing a fish finder rather than catching fish for you.

We ship to the US and Canada. Our QYSEA dealer network serves other regions.
