The Tamaya sextants from Japan have long been popular among merchant mariners around the world. They are unique in that their construction combines the lighter weight of an aluminum frame with the slightly higher accuracy of a bronze arc (the best of both worlds). The arc is easily read, with white engravings on black finished bronze. The optical system is designed to ensure maximum performance, including excellent LED electric lighting.  The sunshade on its horizon mirror is a new feature, which blocks unwanted sunlight.

The Spica is a full sized sextants and comes standard with a plastic carrying case, an adjusting wrench, two dry cell UM-3 batteries, and one LED bulb. Scopes are sold separately.

  • All optics are fully coated
  • Interchangeable telescopes available in 4×40, 7×35 or 3.5×40 (sold separately)
  • Sextant can be stored in fitted case with scope mounted

    I just bought a Tamaya Spica 733 at an estate sale. It is complete in the wooden case. My question is how to I change the light bulb and what number is the bulb, also where can I buy one?

      I have a few light bulbs available here. My price would be Euro 5/p. (=some $6.00) leaving home. Transportation and taxes if any to be charged to you.
