With the sloping noses on many of today's cars, it's difficult to judge distance.
And SUVs and vans almost take up the entire garage. Park Zone takes all the hassle out of positioning your vehicle. Using sophisticated ultrasonic technology, the sensor unit monitors your vehicle's approach. The display unit, mounted higher for perfect visibility, lets you know how close you are to your pre-set "park zone" by changing from green to yellow and finally red. Park Zone installs in minutes, using only a screwdriver. Uses 4 AA batteries (not included) or plug in the AC adapter (included).
