Greetings Aerosynth and welcome to the world of diving. It is far more than what meets the eye, and all types / configurations are not for everyone. This was previously stated and very obvious in the issues that have been discussed in your thread.
It was not long ago that I was a AOW moving up the chain to Rescue and wondering what was next. I took my time honing skills and sought the methods and gear to make the dives I wanted to do safely.
In cold water redundancy makes sense and thus double it was. This opened the door to a whole new world. With this addition came more training which lead to deeper, longer, awesome dives. In just a few short years I have come to understand that Tech diving is far bigger than many people will ever comprehend.
For those divers who seek more, and are willing to commit time, money, training Tech is the means to an end. It is a method to achieve more advanced dives in a safe manor.
It is not a easy path but a rewarding one in my experience and I am but a fledgling.
I personally believe that if you wish to pursue your dive goals and they are taking you into Tech environments then embrace it. Train hard acknowledge the risks and how they are managed.
For one group to disrespect one another is futile we are part of the same body of divers. To battle back and forth is counter productive.
Proceed with your own dive goals and training to achieve them. Good luck.
CamG Keep diving....Keep training....Keep learning!
