This might be considered OT, but I still haven't figured out how to use the metal detector properly. Embarrassed Can anyone tell me?
In the likely event that you wanted a serious answer - if you point it at a mine it makes a high-pitched sound. So if you advance slowly, waving it back and forth as you go, you have a chance of picking up an enemy mine. Just listen for the beeping sound.
Try it on a local server by first laying a mine and then aiming your mine detector on it
