Nitrox Requirement

However reality is that most of the TC dive stores do not have Nitrox. More than 10 years ago there were two Stores doing the Nitrox Blending. Today, lets count how many TC stores can Blend Nitrox? And are doing good business selling Nitrox. Lots of stores just advertise Nitrox classes.

Many of the store owners gripe about how much it cost to rent a few big O2 tanks and to get O2 whips for trans-filling. We are talking about reasonable expenses. A good Nitrox computer costs more. Hi

This tells the use of Nitrox. Yes increased usage over the last few years, but not as much as in other locations. How many divers own computers and how many do have Nitrox computers?
Most of the OW divers do not know Nitrox . Unless they have used the extended Bottom time advantages in the 60-110ft range (Lifeabords). Personally I highly recommend OW diver to take the classes and use the advantages of Nitrox.

I use Nitrox for the Safety and the extended Bottom time only on OC and with SCR. For Reef diving I will use Nitrox only when I put on a third or fourth dive for the day. You will feel definitly less tired after a dive using Nitrox. For cold water I will definitly use Nitrox if I have the choice.

Requiring Nitrox classes not really but it could be part of a AOW class as an elect. You learn to understand what partial pressure is. A Nitrox class opens the Horizon to the technical diving.

Rebreathers for everyone I would say hardly. Rebreathers for deep and long diving definitly; again it is driven by cost of the gas. Twin-sets do have a place but they get cost prohibitive as deeper the dive goes. Rebreathers cheaper; Hardly, SCR like Dolphin are reliable and have advantages for Recreational dept. For technical dives get ready to spend $7-10k and more for a good CCR model with an excellent safety record (no accidents). Around Rebreathers Safety and Reliability is what really counts.
