Mark 3 Marine Sextant
Mfr # 11. Mark 3 Marine Sextant Sometimes referred to as a "lifeboat" sextant, the Mark 3 is an inexpensive training sextant. Yet this model has taken sailors around the world, too! It is full-sized and has sunshades, but no optical magnification to help you find dim celestial bodies. Comes with instruction booklet.
