Our Verdict: The most accessible professional underwater ROV, making subsurface inspection available to teams of any size.

The Deep Trekker DTG3 is a portable, battery-powered remotely operated vehicle (ROV) designed for underwater inspection of infrastructure, ship hulls, dams, bridges, and submerged pipelines. Weighing just 8 kg, it deploys in minutes without the need for a support vessel or topside power systems.

The DTG3 features a 4K camera with 270° rotating head, powerful LED lighting, and optional tooling including a grabber arm and thickness gauge. Its internal battery provides up to 8 hours of operation, and the handheld controller with integrated display makes it accessible for operators without extensive ROV training.
