Abstract
A compact, retrievable and inexpensive marker buoy has a primary housing in the shape of an hourglass having a throat in the center, and a base. The primary housing has a waterproof chamber situated closer to one end than the other and a non-waterproof chamber at the opposite end. A lid at one end provides access to the waterproof chamber, which chamber contains an unattached battery, a signal receiving device, and an electrical device which are linked to a releasably attachable hook. The base has a corresponding device attached to the hook. A tether is connected from the base to the primary housing unit. A transmitter transmits the necessary command signal to the receiver from above the water.
