Choose which models and sizes to include.

Max is the manufacturer listed max and min expansion range. When you select this, I'll also show you lines indicating where 10% and 60% expansion range is. Many people consider 10% and 60% expansion to be a reasonable usable range for cams, but these numbers may differ from cam to cam and also depend on your risk tolerance.

Usable is 10% to 60% of the max range, unless a manufacturer publishes a different number. Metolius is currently the only manufacturer that publishes a usable range. When you select this option, the entire bar represents the usable range.

Showing the weights will have the bar heights as proportional to the weight of the cam. Hiding the weights will have all the bar heights be the same.
