Hammerhead - Russell Kilgour
The snorkel that doubles your breath holding time, designed for underwater reef exploration
This project aimed at bringing the user benefit and comfort of SCUBA diving to the more popular activity of shallow reef snorkelling. Most of the world’s reefs are over 5 metres deep and casual snorkellers usually float on the surface and struggle to hold a breathe while diving down to gain a closer look at the sea life. Varying levels of fitness and flawed snorkel gear are factors to discomfort while free diving.
The Hammerhead Dive Snorkel provides a portable way to fill a storage vessel to pressure which can provide up to 1 full breath at 10 metre depths and potentially more at shallower depths depending on the user. While breathing through the snorkel at the surface, a double inward facing piston pump is used to compress atmospheric air to a limited 50psi, which is released through a regulator at ambient water pressure during a dive for a comfortable breath. It is slightly negatively buoyant in water which helps reduce exertion while diving and contains a high contrast pressure gauge for visual feedback on breathing and filling. Intended to help improve the ability for breath holding in a safe and individually scalable way, it encourages diving within your limits and reducing the impact of the dangers of SCUBA diving by limiting its depth and pressure capability.
