Do PFDs float well in shallow waters?

Personal flotation devices (PFDs) are designed to provide buoyancy and help keep a person afloat, regardless of water depth. In shallow waters, PFDs can still float effectively, but their performance may be influenced by factors like water current and the position of the wearer. If the water is extremely shallow, the wearer may risk hitting the bottom, which could affect their safety. Overall, PFDs are effective flotation aids in both deep and shallow water situations.
