Top of the SETT pool. The tower was also privately hired to civilian diving clubs for the purpose of recreational diving and dive training. It was a popular 'novelty' dive amongst UK scuba divers since it allowed new trainees to extend their depth experience in a safe, controlled environment with good visibility and warm water temperature – two conditions that are in short supply in the UK.
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non-air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis , and may improve ease of breathing .
"The pros of this configuration include: automatic balancing of the gas supply between the two tanks; thus, no requirement to constantly change regulators underwater during the dive; and in most failure situations, the diver may close a failed valve or isolate a cylinder and thus retain access to all the remaining gas in both the tanks."
