ABSTRACT:
A support for a survey rod having a grip for slidable mounting on a survey rod with a first leg and a second leg rotably connected to such grip. Two spring rods each have a first end and a second end. A first end of the first spring is attached either directly to the survey rod below the grip of the support or to a collar that is connected to the survey rod below the grip of the support, and a second end of the first spring rod is connected, preferably rotatably, to the first leg. A first end of a second leg is attached in the same manner as the first end of the first leg to the survey rod, and a second end of the first leg is rotatably connected to the grip. Preferably, the first and second spring rods are resilient and rotatably mounted to the legs.
