Abstract
A compartmentalized full face mask having a flexible sealing flange around the periphery thereof for sealing the body of the mask against a diver's face. The body of the mask has an upper facially oriented opening for receipt of a viewing lens, and a lower opening for receipt of an accessory plate. The lens and accessory plate are secured in the face mask by a band which circumscribes the outer periphery of the body of the face mask for tightly holding the viewing lens and accessory plate in a groove in the body of the mask. The lens and accessory plate partially define an upper and lower chamber with a nose portion and a sealing flange dividing them. The sealing flange provides a lower chamber which can be utilized with accessories of various types in a manner not possible in the prior art. The lower chamber also serves to enhance the underwater sound transmission capabilities of the mask. The lower chamber in one configuration of accessory plate receives a plug in its accessory plate or other opening, for attachment to a second stage regulator or other breathing device. The plug can be moved and substituted by various accessories as well as providing an overall adjustability of the mask with respect to the diver's mouth. The mask is held on a diver's head by means of an elastomeric spider having adjustable attachment means connected to the peripheral portions of the mask.
