The T3 is Atomic’s showcase piece, built to prove what a titanium-billet reg can do on weight and corrosion resistance. It’s mostly bought by travel-heavy divers and pros who fly with their own gear constantly and want every ounce off the kit bag, rather than by budget-conscious recreational divers.
