Abstract
The dampening device comprises a first member, preferably a tubular member, which is to be positioned at the end of the surveying rod which is to be directed to the ground, a second member, preferably a post, being at least partially slidable directly or indirectly along the first member in a longitudinal direction and for being directly or indirectly connected to a tip which is to be placed on the ground, wherein the first and second members overlap at least in one position at least partially along the longitudinal direction, and at least one elastic dampening member which is directly or indirectly housed by the first and/or second member and disposed such that it is compressed by a movement of the first member and the second member relative to each other in the longitudinal direction, so that mechanical shock exerted to the surveying rod and/or the tip can be dampened by elastic deformation of the dampening member.
