Weems & Plath Tamaya Spica Sextant - MS 733

Tamaya is known the world over for high-quality craftsmanship and precision. Because of their sterling reputation, we offer two sextants from this Japanese company.

The full-size Tamaya Spica Sextant is confidently used by ocean-going navigators because its optical system is designed to ensure maximum performance, including excellent LED electric lighting.

The frame construction is lightweight aluminum alloy with a corrosion-resistant black finish. The arc is easily read, with white engravings on black finished bronze.

The Spica Sextant comes standard with a plastic carrying case, an adjusting wrench, two dry cell UM-3 batteries, and two LED bulbs.

Scopes are sold separately. (See also Tamaya Jupiter Sextant, MS 833)
