The invention relates to an automatic retractable float for use with a crab net including a body which floats in water and an automatic retraction and extension mechanism for automatically extending and retracting line from the body. In use the line is attached to the crab net, the crab net deployed and the body floats when in water towards the surface of the water. The automatic extension and retraction mechanism causes the line to be extended and retracted between the body on the surface of the water and the crab net, substantially keeping the line taut to help prevent tangling. The invention also relates to a method of use.
