Claims
- 1. Diver's headwear comprising a body portion having means for securing it to a person's head;
- a window opening in said body portion, to be positioned in use so as to enable the diver to see through it;
- a transparent window sealedly mounted in said window opening; and
- a multiplicity of illuminating means disposed peripherally of said window opening, said illuminating means being connectible to an electrical circuit to energize the illuminating means selectively, illumination from the selectively energized illuminating means simulating natural daylight from above to the diver when underwater, thereby enabling said diver to sense visually and instinctively vertical and horizontal directions relative to his own orientation in the water.
- 2. The headwear defined in claim 1 including sensing means to be supported by the diver, said sensing means being gravity operated for selective energization of those illuminating means which indicate at that instant the vertical direction.
- 3. The headwear defined in claim 2, wherein said illuminating means comprises a multiplicity of light emitting diodes.
