An improved Schlereth Classic Ageton tablular method complements the classic sin cos pocket calculator method and would be a quick learn for those already doing sight reduction by pocket trig calculator. The Ix Haversine Doniol Method is the coolest of all especially for the minimalist. I have a one page version that can fold into the wallet. An excellent tabular sight reduction method to have in the CN tool bag. I recommend learning both methods to backup the pocket calculator.
