The Quintant is similar to the more common and well known Sextant, it is used in the same way but the Quintant has the ability to measure larger angles than the Sextant.

The Quintant gets it's name from the Latin word for 'a fifth' because it has an arc equivalent to one-fifth of a circle (72 degrees). Due to the doubling effect of the two mirrors this means it can measure angles of up to 144 degrees.

The silver scale is engraved from -5 degrees to 175 degrees and can measure angles up to 148 degrees, the scale is divided into 10 minute increments. The index arm has swinging scale magnifier and the silver Vernier scale reads from 0 to 10 seconds of arc.
