Range-Extenders are used to double, triple or multiply the range of the Precision-Dial. To do a length between 0 and 2 inches, no need for Extender, just use the dial. To do a length between 2 and 4 inches, put one extender on top of the dial and set the length from the dial. Each range extender increases length by 2 inches, the maximum length you can dial. This allows cuts even on waist long hair. Here is an example of how many Extenders you need for long hair: If you want your hair to measure more than 10 and less than 12 inches from the neck-hair-line you would need three extra Extenders.Order Range Extender
