The Wireless Smart Gate has all the features of the wired Smart Gate. It has dual photogate beams spaced at 1.5 cm to accurately measure speed and velocity. The built-in laser switch (when used with any laser) allows you to time objects too large to fit through the arms of the Smart Gate. The integrated slot on the arm of the Smart Gate receives photogate tape that also helps measure the movement of larger and faster objects, like model rockets. The auxiliary port is for adding an additional photogate head or Time-of-Flight Accessory.
We do not recommend using two Wireless Smart Gates in the same experiment unless the measured times are relatively long (greater than one-half second) since synchronization is limited to 2 ms.
