In my last post I showed you a geologic compass in the Freiberg version. Below is a link on how to use a geological compass in the field. The compass used in the video is a Breithaupt model but usage is basicly identical. The only difference is the location of the dip scale which is not located on the sides of the joint but on the inside above the compass circle, as you will see in the video. Unfortunately there is no such video in English language. The video here is exclusively in German.
