I'm listing this locally before i list it on a large auction site this weekend. These are one of the smallest lightest radar units . the dome is 12 inches in dia. and 9 lbs. the screen is lcd not crt like the older ones. This is a working removal . max range is 16 miles. Firm on price this will sell for 450 on alternative site easily .It's set up for overhead mount but can easily be changed back to dash mount.
