OKM ROVER C4: how does it work?
First of all, the OKM ROVER C4 detector is a combination of 3 existing OKM detectors (Rover C, Rover C II, Rover Gold). It was created to facilitate metal detection. With it, you can prospect for rings, jewels, coins, etc., as well as empty structures such as tunnels, caverns, chambers, etc.
What’s more, the OKM ROVER C4 detector can be used in dark environments thanks to its LED display backlighting. As a result, this LED sphere also emits colored light to visualize the metals and cavities detected when scanning the ground.
For this reason, it can be used to calculate target dimensions, position and depth.
