Parking in garages can sometimes be tricky as it is often difficult to know where exactly the end of the car is. A tennis ball on a string or a board on the floor can help to find the right spot, but hanging a tennis ball at the correct position or keeping the board from moving make these solutions unreliable. For this reason an ultrasonic parking assistant has been developed. “ParkAid” solves the parking problem in a simple and inexpensive way. For just about $40 (€30), enclosure and power supply included, we can be sure to park our car the way it deserves.
