Accutoe differences??

[turtle5353]

I have been looking to buy an accutoe system to help setup my sons kart. I have seen a pro, advanced, and Es. What's the differences between them all?

The Advance has a built in camber guage and I like the way the rear mounts secures inside the axle. Es has a separate camber guage so front mirror needs removed to check camber then once camber set you need to reattach the mirror to reset toe. The Advance saves these steps but is more expensive.
