. I will stop the scam immediately, too much "range" for this size. No matter how small the instrument is, it must be MAX. +/- 3 degrees, one degree less wouldn't hurt either. It's too imprecise to get a clear scale with a long range in a tiny rut, and to be honest most "road" cars will be in the -0.5 to 1.5 degree camber range anyway , while cars with high characteristics clearly do not fit into this range. .All in all, it's in my pocket in case someone breaks a joystick or something in the desert. This tool is just enough to get close enough to ride home without damaging the tires and due to its small size it takes up very little space in my kit. It will also be enough to get you back on the road after some chassis work. on your car at home is at least good enough to get you through until you can get to an wheel aligner without wrecking your tires.
