Why do Tripods have 3 legs?

The three-legged (triangular stance) design provides good stability against gravitational loads as well as horizontal shear forces, and better leverage for resisting tipping over due to lateral forces can be achieved by spreading the legs away from the vertical centre.

What is a survey prism?

Optical Survey prisms are a specially designed retro reflector, specifically a corner reflector, that is used to reflect the Electronic Distance Measurement (EDM) beam from a total station. A survey prism reflects the EDM beam back to its source with both a wide angle of incidence and with high precision.

What is a surveyor’s tool called?

Theodolites

The most common surveying equipment is called a theodolite. Theodolites are used to measure the horizontal and vertical angles between points. Surveyors combine the angle data with distances from a chain or tape measure, and it allows them to triangulate the location of any point using trigonometry.

What is the hook on the bottom of a tripod for?

In a nutshell, the hook on the bottom of your tripod is there so you can add more weight to your tripod, which in effect makes it more stable.

Is a taller tripod better?

Tripod Height
I always recommend buying a tripod that matches your height, so that you do not have to bend to look into the viewfinder. Once you put your camera on a tripod, the viewfinder should be at your eye level. It is OK if it goes higher than your eye level because you can always adjust the legs to be shorter.
