The Proximity Mine is simple in use, plant it by pressing Interact Key (Default F/Enter) while holding it, you will drop the item and be given a 5 second window to leave the detection radius.

The detection radius of the proximity mine is 5 metres, if a human or vehicle enters this area, the bomb will go off shortly after a beep. This sound that plays shortly before the explosion can be used to escape the blast radius if you are fast enough.
