This is Tamaya's full-sized "best value" calibrated and fully functional nautical sextant.  The Jupiter sextant has many features of more expensive sextants, but still has impressive +/- 12 arcsecond accuracy.  Built to rigid specifications and engineered for quality, the Jupiter professional marine sextant is the most popular selling sextant Tamaya offers.
The large 57x42 mm index mirror and 57 mm diameter horizon mirror offer a bright view.  A natural and comfortable grip is provided by the inclined handle.  The Tamaya Jupiter Sextant has full illumination on both the arc and drum.  Interchangeable 4x40 or 7x35 monocular scopes are available.
Specifications:

-5° to 125°.

This sextant is fully functional for navigation and comes with a certificate of calibration.  The Tamaya Jupiter Sextant with Storage Case normally sells for $1,979.99, but we offer it for only $1,699.99.
Note that at least one telescope is required for use.  The storage case can hold the sextant and both telescopes.  A brighter image is produced by the 4x40 scope than the 7x35 monocular, and is best for low-light conditions or when the vessel is heaving.  The 4x40 scope has fully coated optics and a large 40 mm objective lens to produce a clear four-power non-inverted (upright) image.  The Tamaya 7x35 monocular scope produces a sharp high power 7-power wide angle non-inverted image.  It is more powerful than the 4x40 scope and yields more accurate readings.  The scope has fully coated optics and a large 35 mm objective lens.  Either scope fits both Tamaya's Jupiter and Spica Sextants.  The 4x40 Scope is on sale for only $259.99 and the 7x35 Monocular Scope is on sale for only $499.99.
We also offer the more accurate Tamaya Spica Sextant, the Stanley London Mark 3 Sextant, and the C. Plath Decorative Antique Reproduction Sextant.
