"Second": Due to the scope of each probe test is a fixed angle of Dell pa10 adapter will naturally produce blind corner, if for safety reasons, of course, a number of multi-probe can be mounted for more information. Such as side-mounted probe, when the vehicle turns, the vehicle and the distance between obstacles on both sides will also be displayed. In fact today, reversing reversing radar has not only to provide security information, and even offers driving distance on both sides of security information. From the economical point of view, generally four probes installed in the rear of the vehicle suitable conditions permit can also be installed at the front of two probes.
