A bstract A 3‐component flux gate magnetometer has been built for use in 1½ inch drill‐holes. It has an accuracy of 1 mgs. It requires 2–3 men to operate it and they can take measurements in up to 3 100 metre holes in one day. The instrument has definitely proved its worth in describing the‘general’ geology of an ore‐body, and it is now used on a routine basis.
