The mob radar can detect mobs in a large radius around it, and is unobstructed by blocks in the way. It will display their positions on the NSEW plane, signified with the appropriate icon. If you have a motion tracker in your inventory, the radar will also render a HUD of sorts to alert you to mob positions near you.
