A Diving Helmet is a rigid head enclosure with a breathing gas supply used in underwater diving. They are worn mainly by professional divers engaged in surface-supplied diving, though some models can be used with scuba equipment. The upper part of the helmet, known colloquially as the hat or bonnet, may be sealed directly to the diver using a neck dam, connected to a diving suit by a lower part, known as a breastplate, or corselet, depending on regional language preferences, or simply rest on the diver’s shoulders, with an open bottom, for shallow water use.

Lightweight helmets: Commercial diver and inventor Joe Savoie is credited with inventing the helmet neck dam in the 1960s, which made possible a new era of lightweight helmets, including the Kirby Morgan Superlite series (an adaption of Morgan’s existing “Band Mask” into a full helmet.) Savoie did not patent this invention, though he did hold patents on other diving equipment, which allowed widespread development of the concept by other manufacturers. The neck dam seals the helmet around the diver’s neck in the same way that a dry suit neck seal works, using similar materials. This allows the helmet to be carried on the head and not supported by the shoulders on a corselet (breastplate), so the helmet can turn with the head and can therefore be a much closer fit, which considerably reduces the volume, and as the helmet must be ballasted for neutral buoyancy, the overall weight is reduced. Neck dams were already in use on space suits in Project Mercury, and neck seals had been used on dry suits even longer, but Savoie was the first to use the technology to seal the underside of a diving helmet.
