aha, there is a problem with using a caliper. You get a measurement for 1/2 the waist of the ski, but you still have to measure off one edge that amount and howya' gonna' do that? my doohicky gives you marks across the ski to use after you calculate, calipers don't have a scale across the surface of the ski. or am I nuts?
Don't know about yours Dav but my digital one also has a scale on the bar so you can use it in exactly the same way. Measuring from both sides and marking
