Dive to 150 feet with backmounted doubles with 18/45. Technical or not technical?
If you stay long enough to incur a mandatory deco obligation it's technical. You will no longer have direct access to the surface.

Dive to 150 feet with backmounted doubles with 18/45. Technical or not technical?
worry more about NDL and deco than the unbreathable gas in your back mounted set shows me that you urgently need to take a course.
Every thing is easy til you have a problem...I was throwing it out there to see if I was missing something like the elephant in the room...
I would consider it a dangerous and non-scientifically (i.e. poorly) planned dive.Sand is about 125 feet and the wreck goes up to about 70 feet.
I dive Independent doubles and used air in one tank with the long hose and used 40% in the other under my chin.
I happen to have a Perdix so I marked 21% and 40% did the gas switches and just followed my NDLs.
I did not announce what I was doing either.
Would you consider this a technical dive?
... my intention was to hit 124 feet or the bottom - I did want to explore...
Other than what I mentioned (OxTox by stupidity) - I have not heard a solid argument for why this is a bad idea. I was throwing it out there to see if I was missing something like the elephant in the room... I dont intend on using this method every dive but it sounds like from what I heard - caution and process are key to safety which if you read my OP seems to me to be top of the list.
Nope not worried - I did not want this to turn into a rant of no deco without instruction debate. Maybe I overstated it - so it would not be that thread again...
