Can a theodolite measure distances?
Yes, but it is an indirect process requiring two operators- or at least a fixed surveying target on which the surveyor aligns his Stadia wires ( popularily Cross hairs) There are different scales but a base-line of l00 feet and in some cases l00 power is increasingly standard. consulting a table and some number-juggling is needed to get the distance, and more importantly the Vertical rise and Fall ( gradient, up or down) The theodolite is better adapted to this type of surveying, than a mere ( range finder)- which is can be used for- but with some shifting of tactics and technique. The basic tables in the technical manuals assume a base line distance of l00 feet, then there are angles, etc.

If the worker should "Slip or Fall", the device senses the downwardacceleration and locks up, preventing the fall. Most devices also include some type of braking/energyabsorbingfunction to limit the forces on the human body and anchorage point of the device.Was originally designed and used in the early part of the 20thcenturyfor use in the mines in and around SALA Sweden. Still in use today with great reputation as being the best method of "Fall Arrest".
