| There is a school of thought that CCR is not suitable or easiest used for dives where numerous depth changes are forced upon the diver. An example of this would be a cave dive where the depth was constantly changing and the diver is forced to follow the cave. The problems of buoyancy control and managing the volume of the counter lungs are an irritation and the gas usage is high so gas logistics of the CCR become distorted.
Add to this the small cylinder size on the Evo. When i first used the classic with its 3ltr cylinders i used a lot of diluent on wing inflation and suit inflation. As a result a two dive day would push the little 3ltr tanks if i started with a light fill. This early lack of buoyancy control is similar to being forced to run a jagged profile. As a result the little 2ltr tanks on the Evo would be hard pushed to cope.
Obviously the cure for this is off board suit and wing inflation but the article obviously was not well informed. What most people consider to be "multi level diving" is perfectly suited to the Evo or any other CCR I can think of.
Hope this helps.
