The word Argon comes from the Greek word for "lazy", a name it earned for being one of the least reactive gases in Earth's atmosphere. Early on, trimix divers inflated their drysuits with helium, but often got much colder faster because helium is a highly reactive gas. They started carrying separate tanks of air to inflate their suits to avoid using helium. Eventually divers began using argon gas to inflate their suits because it was the "warmest" gas they could use for insulation. Divers looking to increase their bottom times and push the boundaries of their gear can look to argon inflation systems for significant improvement in drysuit warmth.
WARNING: Argon cannot support life! Argon inflator set-ups cannot double as a pony tank, so do not breathe argon unless you're prepared to reap the consequences.
CARE: Take care of your argon system by properly rinsing it after your dives.
