Identify This

I am trying to find out information on this object.
There is no broad arrow stamped on the instrument.
The leather sheath would indicate that it would be used in the field and the thread at the top obviously indicates an attachment like a compass or similar. The leather of the sheath appears to indicate that the object is over 75 yo.
The item looks like a modern day version of a wooden “Jacob’s Staff” which was used in colonial times for surveying.

I would appreciate any information or comment on the object.

Thank you
