The factory fin settings are 2.520" deep, with a length of 6.840", and 0.745" distance from the tail of the ski (see diagram A). A caliper is the best way to check these measurements. Fin tuning instructions, an Allen wrench and warranty information are included with your ski. The binding placement for each size ski is listed below. This is measured from the heel of the front binding to the tail of the ski.

Fin Setting Advice From Joel
“My advice would be for skiers to begin with the stock settings before experimenting with both advanced option one and two. Option one is slightly more stable, however, option two will require less movement to initiate the turn. If you cannot decide between option one and two, remember the skis will work extremely well with either setting.
Generally, elite skiers run more surface area and will prefer to run their fin back/deep/short (option1) or forward/shallow/long (option 2).
It's possible to 'tweak' your fin for years and never truly test each end of the spectrum, however, this chart should significantly reduce the time and knowledge required to find settings which match your skiing.”
