A marker buoy includes a base with a post coupled to and extending therefrom, a line attached to the post and is wrapped about a portion thereof, and a float attached to the line and fitted over the wrapped portion of the post. When the marker buoy is deployed near the bottom of a body of water, the base sinks to the bottom and the float rises to the surface of the body of water causing the line to unwrap from the post. The line length is user set as a function of depth and speed of the surface current at the time of buoy placement and use.
