I was looking at the TEC course equivalency charts for PADI and TDI. it looks like each agency does not credit each other and other agencies courses in exactly the same way.
Two deco tanks in addition to bottom gas are not used with PADI until TEC 50. I was wondering at what level courses do NAUI and TDI normally have divers receive training on the use of two deco tanks in addition to bottom gas.
This question arose as a non-PADI trained TEC diver mentioned that he only used 100% o2 to deco at 20 feet and used bottom gas for any other stops.
