Welcome to Lancetta, Inc.

The Car Seeker (patent pending) contains no electronics, and no batteries for its operation. All it has is a specially designed magnetic cylinder that is immersed in fluid. This part bears symmetrically separated parts of a picture. A transparent rotating bezel contains the other part of the same picture

To lock a car's location, simply point the Car Seeker at the location of your destination as you stand next to your parked car - adjusting the bezel until the two parts of the Car Seeker are aligned to create the original logo, name, phrase, or graphics

To find the parked car, just point the Car Seeker in different directions while observing the resulting graphics. Generally, the picture will look like the one on this picture (the pictures represent no real device and serve only as an illustration for the operation principles)

As you can see, when the Car Seeker is pointed in the direction of the parked car, it will display the correct logo or picture - indicating the correct direction to take to the location of the car.
Compare these two logos on this picture. The Car Seeker graphic on the top is incorrect, because the BMW logo is crippled (the reason being is that the Car Seeker is pointed in the wrong direction). The Car Seeker on the bottom, on the other hand, is perfectly aligned with the direction of the car (as is the BMW logo on it). If the Logo is correct, then the direction is correct as well.
