The anchor device includes a post movably connected to a base and is lockable in shovel, anchor and storage positions. First, it is locked in a shovel position and a hole is dug in beach sand. The anchor device is then disengaged from the shovel position and then locked into an anchor position and then inserted into the hole and then covered with beach sand to secure the post portion of the anchor device in a vertical position with a portion of the post exposed above the surface of the sand. A beach umbrella is inserted into and secured to the post. To remove the anchor device from the sand, the anchor lock position is disengaged from above the sand to permit the post and the base to freely pivot relative to each other so the base and post can be easily pulled from the sand.
