What's gas switching
Gas switching is as it sounds, switching gas mixtures while under the surface. Practised by only very capable divers, but becoming increasingly popular, gas switching can increase bottom time and decrease decompression time significantly. Clearly, this exercise would require an advanced dive computer. The Suunto Vytec is up to the challenge. When in Nitrox mode the user can preset up to three different gas-mixes containing 21-99% oxygen. Preferred gas mixes can be stored as default (e.g. EAN32, EAN50, EAN99), and be set ON or OFF for each dive, or modified as needed. The Suunto Vytec provides easy and reliable gas switching between enabled gases during the dive.
