A high visibility signaling device typically used to maintain a set depth during decompression or safety stops. This PSD is designed to be inflated by purging your regulator under the opening. Air is trapped by the unique one way duck bill valve, and an over pressure valve takes care of expanding air during ascent. A small lead weight assists in keeping the PSD in a vertical position.
