The issue is prompted by the recent spike in Helium prices. I went for a "normal" dive expected to bottom around 180 feet and so asked for a usual mix of 21/35. Well the price for this (into an empty set of double 120's) was around $240 -- and I highly respect and trust the dive shop and its owner who filled the tanks.
Six months ago I lost my job, although I have started a new one in the past 1 1/2 months. I am ok financially now but need to be cautious. I can afford a boat ticket, deco fills, and 80 or 90 dollars of trimix but not a total of $340 for just the main tanks and boat ticket (plus more for deco bottles) for one dive.
I have always "played by the rules" and never exceeded a PPN2 of 4. I know it used to be the norm for people to dive 200+ on air but I have not. I am not aware of any narced sensations at a PPN2 of 4 and seem able to do the required tasks, such as blowing bags alone, etc., without difficulty.
If I could dive air to 185 it would certainly increase my ability to dive more frequently. I am not asking for any guarantees or definitive answers but I am curious how others who have dove air (recently) to 185-ish (1/3 more PPN2), have to say about it.
Thanks, and I DO take everything I hear with at least a few grains of salt.
