Abstract
A survey tripod for use in uneven terrain which includes a center pole and a pair of support legs, each leg is pivotally attached to a slideable clamp on the upper part of the pole for vertical adjustment of each leg. The lower end of each leg is connected to the pole with a brace, both ends of each brace having pivotal connections for adjustment of the legs. There is a clamp connecting both braces to the lower part of the pole which permits anchoring the brace, and permits additional vertical adjustment of the legs relative to the center pole. A telescopic tube within the pole can be extended upwardly to increase the effective height of the pole. A survey instrument can be attached to the tip of the telescopic tube.
