Exit wands, also known as magnetometers, sense change in the Earth's magnetic field. They are used to detect the presence of a vehicle by reading the electromagnetic waves it creates through its movement. GateMate Self-Contained Free Exit Systems open an automatic gate allowing safe and secure passage without using a remote, key fob, or keypad. All Ramset Free Exit Wands are self-contained systems that connect directly to any gate operator without an external output board and are solar compatible.
