A Comparative Evaluation of the Standard U.S. Navy Shallow Water Diver's Mask and the Commercial P and E Manufacturing Company's Mask
Abstract:
A new commercial shallow water divers mask is evaluated in comparison with the older U.S.N. Standard Shallow Water Divers Mask Jack Brown. The new mask, manufactured by P and E Manufacturing Co., is considered a good shallow water mask but is in no way superior. The standard mask is preferred. Several deficiencies in the P and E mask are noted.
