Captain Campbell's Vernier Sextant

Brass replica of the Campbell Vernier Sextant

Full-size vernier sextants were, in skilled hands, instruments of great accuracy, practicality and beauty – a joy to own and use, but also essential to the safety of the ship.

Our replica is dedicated to Royal Navy Captain John Campbell, who developed the instrument from its predecessor, the Octant, in 1757. Crucially his invention was close in time to that of accurate, portable chronometers, and it was the combination of the two which finally made navigation a science rather than guesswork, saving countless lives. This importance gave rise to the air of mystique which surrounds the instrument and its use, even in today’s age of electronic wizardry.

Detailing is impressive, with hardwood handle and protective box, six shades of varying intensity, and a powerful telescope. Fully functioning parts but not intended for serious use.

Instrument 20x17cm, box 26cm square.
