Sextant.
People used the North Star as a navigational tool by determining the direction they were traveling based on its fixed position in the northern sky. By using the North Star as a reference point, travelers could determine their latitude and maintain a straight course when sailing or traveling over land.
Anemometer is the tool used to determine wind speed and direction. It typically consists of cups that rotate with the wind, and the speed of rotation is measured to determine wind speed.
A tool commonly used to place scratches in metal is a scribe or a metal engraving tool. These tools typically have sharp tips that can create precise lines or patterns on the surface of the metal.
A compass is a tool often used to determine directions. It works by pointing towards the Earth's magnetic North pole, providing a reference for North, South, East, and West.
An anemometer is the easiest and best way. To tell how fast the speed is using an anemometer, determine how fast the anemometer is spinning with a speedometer if possible.

A wave gauge or wave recorder is the tool used to determine pitch in waves. It measures the height and frequency of waves, which can then be used to calculate the pitch of the waves.

Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
