This is a new Smart Camber Systems. I had already bought one and I was given this one. I opened it to make sure it works, everything is in it and there is nothing wrong with it at all.

 

Features and Uses:

Use on 5" to 22" diameter wheels

 

Removable digital modules makes it two tools in one. Use the module to measure: drive shaft angles, fabrication, fixture and body work, wing angles

 

Camber can be measured on non-flat surfaces (garage floors, parking lots, and even on a trailer

Requires no additional attachments to wheel or hub. Simply hold the tool against the wheel.
