;;;;;;;;;All REC divers know is al80's anything else is seen as tech stuff. training is crap and they are told that you can go to 130 right out of OW. Where do they get such ideas. The industry,,,,,,,, including the social media associated with it.
Just dove Blue Hole in Belize to 138’ with AL80 on air last week.
Can do no problemHello. I was thinking back over the years. I worked for a Dive shop years ago as a Divemaster.
We did our deep dives on the Chester Poling off Gloucester, Mass. for the P.A.D.I. Advanced Open Water Course.
At high tide the the wreck sits in 108fsw. It always amazed me that people would do this dive "Normally." on single aluminum 80's without any type of redundancy.
I always thought it was insane???? Divers would come back on board with extremely low pressure readings on their gauges. Too me, it left no room for error, or any type of contingency whatsoever. At that time, I was diving with an Aluminum 100 cubic 3300 P.S.I. (Air.) with a 30 cubic pony bottle.(Air.)
20 years ago the shop did not have "Nitrox." (This is not an enriched air scenario.)
Staying within N.D.L.......I don't care how long you've been diving, or if, your'e the best breather on the planet your max bottom time is approximately 18 to 20 minutes, at 100fsw, not including the 3 min Safety stop.
So, I was curious? The question is: Would you personally make this dive, staying within N.D.L. on air........No redundancy?
Cheers.
I'd prefer nitrox, but 108feet is well within normal recreational range on an al80. Seems odd that you would be so worried about such an innocuous dive to me. Maybe diving just isn't for you?Hello. I was thinking back over the years. I worked for a Dive shop years ago as a Divemaster.

Curious minds would like to know.
- What was your proper min gas reserve?
- At which bottom time did you pass that reserve?
- How did that bottom time square with your NDL?
- Did you overstay your proper min gas time, or did you leave the bottom when you reached your proper min gas reserve?
- If there was a mismatch between your min gas time and your NDL, did you have sufficient reserves and a redundant gas supply in case you had to do deco time?
