I'm sure you were trying to be helpful but I found your responses otherwise. First you said it was in the rules (which it isn't), then you said "If you are on the internet you have access to them", then you said it was on the R&A site but did not suggest where. But thank you all the same for pointing out that the issue of a compass has been covered by the R&A.
it is in the Rules, you quoted them -
"The rules says I cannot use any device or equipment
a. That might assist him in making a stroke or in his play; or
b. For the purpose of gauging or measuring distance or conditions that
might affect his play"
the Decisions are part of the Rules, and clarify issues raised when appropriate. In this case that a compass is equipment considered to gauge conditions that are considered to affect play.
another decision sets out in a little more detail some of these conditions "....gradient, wind speed and/or direction, temperature or other environmental factors."
