The Cross-Staff was used at sea from the beginning of the 16th century until the first half of the 18th century.
It was used to measure the sun's altitude, especially at the meridian passage. With the knowledge of the sun's declination, the mariner could then obtain his latitude.
The staff is original, with the inscription.
The cross pieces are replicas. Different cross pieces were used depending on the altitude.
A different scale is on each side of the staff.

This compass differs from modern compasses, as it utilizes magnetic induction damping rather than fluid to dampen needle oscillation.
It is widely used by geologists and surveyors to make accurate degree and angle.
• Compass survey is a method of surveying by taking bearings and linear distances to produce plan.
• Bearing is measured using prismatic compass, while the linear distance is measured using measuring tape.
• Bearing in compass surveying means angle is made by chain line or survey line by referring it to magnetic meridian or magnetic north.
