Somewhere this very moment there may be a naval reserve instructor attempting to instruct a group of reservists in the construction and operation of the sextant. He no doubt has only two or three instruments for the entire group and is struggling to make his explanations clear by the use of rather complicated drawings on a blackboard. How much more easily all of this could be accomplished if each man in the group was to sit down to a bench or table and actually make his own sextant with his hands. Surely there is no better way of teaching a man how a sextant is made, assembled, and adjusted than actually to let him do it.
The writer has for the past five years been conducting sea scout officers’ training schools in Boston, Massachusetts, and during this time has developed a very simple, inexpensive, and accurately made sextant described in this article. This sextant can be constructed by any naval reservist of normal intelligence and without the benefit of a great deal of mechanical or technical knowledge.
