GeoAccess - Underwater Inspections

Once the preserve of traditional remotely operated vehicles (ROVs), GeoAccess can now offer underwater inspections, photography and video with our submersible drone, the Chasing-Innovation Gladius V2. We strongly believe that we can offer a cost-effective, comprehensive underwater inspection service, providing high-resolution photography and 4K video, without compromising quality and safety, and without having to rely on larger, cumbersome, less manoeuvrable ROVs.


The Detail

The Gladius V2 can be operated in freshwater and saltwater environments. It is rapidly deployable from shore or boat and requires a crew of two to operate (pilot and technician). The Gladius is attached to a 100m tether with a towable wi-fi buoy to extend the operating range if required. It can operate at depths up to 100m, has an endurance of up to 4.5 hours with rapid recharge times of both drone and wi-fi buoy in less than 2 hours. Following several successful test-dives on the Isle of Wight during August 2018, we are now ready to go operational.
