Many years of use by ocean-going navigators have proven the high quality of the Tamaya Spica Nautical Sextant.

resistant black finish and a Bronze arc for highly accurate +/-10 arcsecond readings.
We offer 4x40mm and 7x35mm telescopes that are interchangeable and have special rubber eye protectors.
The Tamaya Spica Nautical Sextant offers full illumination of both the arc and drum.
The fitted case can store the sextant with either scope mounted.

four-power upright image.
The Tamaya 7x35 monocular scope is more powerful than the 4x40 scope and produces more accurate readings.
The Tamaya 7x35 monocular scope produces a clear high power 7-power wide angle non-inverted image.

Either scope fits both Tamaya's Spica and Jupiter Sextants and the storage case can hold the sextant and both telescopes.
