Why Choose the Mark 15?
While the Mark 3 is a great emergency backup, the Mark 15 is a true navigational tool. Its micrometer drum and sun shades make it vastly more accurate for determining your position. It is favored by the U.S. Coast Guard and sailing schools as the ideal training instrument because it behaves exactly like a metal sextant but won't lose its alignment if bumped or dropped.
