Upon successful completion of Tech 1 course a diver will become a fully qualified Technical Diver and be able to use standard Helium mixes of 25/25, 21/35, or 18/45 and decompression gases of 50% or 100% oxygen with the option of a stage bottle (if endorsed). The limits for a UTD Technical 1 diver are 160’/48m, one (1) decompression bottle and the use of one (1) stage bottle (if endorsed). Maximum decompression time when using 100% oxygen for deco is limited to one oxygen cycle (15 minutes) and decompression time is limited to 30 minutes if using Nitrox 50 for deco.
