PoleClinometer will only fit 14mm, 16mm, and 18mm upper shaft diameters. Thankfully, that’s almost every single ski pole, trekking pole, etc. made today (other than the odd shapes pictured above). If you find that your PoleClinometer won’t fit your pole because you have an odd upper shaft diameter, contact us.
How Does It Work?
PoleClinometer uses the shape of your ski pole to do its thing. The typical ski pole is long & narrow, and more-or-less axially symmetric, so you can just dangle it like a plumb bob to ensure it’s vertical. This is critical.
A ski pole has a cylindrical shaft, so lines around it representing slope angles are easy to define (with some pretty basic geometry) and can be read from different perspectives .
The trick is in the “lines”. Each PoleClinometer slope line is defined by the intersection of a hypothetical plane with the surface of the cylindrical pole shaft. Such a line will appear straight only when viewed from any point on that plane, and will otherwise appear curved.
