A nice compass, I have one in the truck (State Forest property).

"The end product of a practitioner depends not only on the equipment used, but with the ability and care used by the operator and his helpers, and the conditions under which the work is performed. A poorly trained or careless operator will obtain poor results with the best equipment....The Sipe-Sumner Vernier Compass in the hands of a poorly trained operator could give mediocre results; a proficient user will get excellent results."
Henry Sipe
Compass Land Surveying
Chapter Ten
“It is unfortunate that all makers of surveying instruments do not have a uniform method of designating the north or south end of compass needles, but that the surveyor must learn and remember whether the blue or white, or weighted or cross-barred end of the needle is the one that points northward.”
Instructions (to forest service employees) For Making Forest Surveys and Maps - 1912
