The Recreational Trimix Program covers the use of Recreational diving mixes in the range of 28 to 40% oxygen with Helium added to
provide an Equivalent Narcotic Depth no greater than 80 fsw. Exposes divers to the simplest form of Trimix diving at recreational depths.
The Program is designed to provide Sport Divers with a breathing medium for extending their dives to Sport Diving Depths by
using Equivalent Narcotic Depth between 40 to 80 fsw at depths up to 100 fsw. The diver may elect to dive the "mix" on tables or computers.
Qualifies divers to: complete no required stop dives using Recreational Trimix Gas mixtures to a depth of 100 fsw or
deeper up to students previous OW qualification level
