Frequently asked

Questions, answered by drone specialists

How deep can an underwater drone go?
Depth depends on the model and tether length. Entry-level units suit shallow recreational use, while professional ROVs from QYSEA FIFISH and the CHASING M2 series reach far greater depths for marine inspection and survey work. The working depth is set by the tether you run, so we help you spec the right cable length for your operation.
What is the difference between an underwater drone and an ROV?
They are the same thing in practice. ROV stands for Remotely Operated Vehicle, the professional term for a tethered underwater drone you control from the surface. Whether a platform is called a drone or an ROV, the principle is identical: a camera and thrusters on a tether, controlled in real time from above the water.
What is the difference between CHASING and QYSEA underwater drones?
Both are leading ROV brands, with different strengths. QYSEA FIFISH is known for its omnidirectional movement and posture lock, with a strong professional range for inspection, aquaculture, and search and recovery. CHASING covers everything from compact recreational units to industrial-grade inspection platforms with modular attachments. Which fits you depends on your depth, your task, and your accessories. We carry both, so we give you a straight comparison rather than push one brand.
Can you use an underwater drone for commercial inspection?
Yes. Professional platforms from QYSEA and CHASING are built for marine inspection, hull surveys, aquaculture, and infrastructure work, with 4K imaging, stable movement, and modular attachments like grabber arms and sonar. We help you match the platform and accessories to your inspection requirements.
How does the tether work and does it limit range?
A tether carries power, control, and live video between the surface and the ROV, which is what allows real-time 4K viewing without the signal loss water causes for wireless systems. The tether length sets your maximum working range and depth, and longer tethers are available for deeper or wider operations.
Are underwater drones suitable for saltwater?
Yes, the platforms here are built for both freshwater and saltwater use. As with any marine equipment, rinsing with fresh water after saltwater use extends the life of the seals and components. We can advise on care and maintenance for your specific conditions.

Choosing the right underwater drone for your operation

Underwater drones, also known as ROVs, have made professional subsea inspection and exploration accessible without a dive team or a crewed vessel. The right platform depends on your working depth, the clarity of your footage, and the tasks you need to perform, from recreational exploration to commercial hull surveys, aquaculture monitoring, and search and recovery. This collection brings together leading ROV brands including QYSEA FIFISH and CHASING, with 4K imaging, omnidirectional movement, and modular attachments such as grabber arms and sonar for serious inspection work.

For operators weighing the investment, an underwater drone replaces slow, costly, and often risky dive operations with a tethered system that delivers real-time 4K video from the surface. Working depth and range are set by the tether length, so spec matters as much as the platform itself. If you are comparing models, depth ratings, or accessories for marine inspection, aquaculture, or survey work, the Scanixx team verifies every spec against the manufacturer and helps you match the right ROV and tether to your operation before you commit. For commercial or multi-unit orders, we prepare custom quotes with volume pricing.
