Well....I've been messing around and chewing on this for a couple years and have been hesitant to pull the trigger and order a bunch for the store, but I'm jonesin' to do so....thus the reality check. For a variety of reasons I think digital angle finders can help to answer the proverbial question of '
what are my edge angles'.
Magnets snap to edges and true bars very nicely providing an absolute positive alignment with an edge. By calibrating a digital angle finder with magnets you can get a very clear idea where your edges truly are at a given location on your skis. Using the edges to calibrate the angle finder and not the base with inherent variability, you can increase reliability at any given point on a ski.
Note that with the (+/-) 0.1° sensitivity, you can drive yourself nuts and never get out the door if you can't stand that the angle is dead on a particular target angle.

Also, you'll be surprised to find how variable any given angle truly can be along an edge.
What are your thoughts?
