Those who dont get it will never agree with us Aldora, LU and Deep Blue type operator lovers in Coz. I love Aldora and will continue to support their exceptional efforts but I cant say that I am without disappointment. IMO they all should offer some sort of Advanced Diver or Experienced Diver program. By this I mean making Nitrox available. Now, if everyone on the boat does not have the same gas then this would obviously be futile.
Our dives with Aldora consistently end with 900 to 1400 lbs. of air. Depths are in excess of 85ft,usually over 95ft and many over 110ft in my log for 1st dives. Second dives are universally in excess of 60ft, usually over 70ft unless we happen to dive Paradise and then your at about 50ft. With these profiles, SI is rather long
.like 1.5-2 hrs. The ending gas issue could be caused by a diver OOA or being at NDL. Since you can't have inexperienced divers doing decompression dives there is obviously no answer to the NDL problem while diving air. I see this as leaving 1/3 or more of my "Aldora Experience" on the boat. Divers with decent SAC rates don't need the 120's but the rest of the experience with Aldora is great. If there was a Nitrox pgm then BT's would be much better and SI would not need to be near as long and thus ending the 2 tank morning dive much earlier. After 6 days of diving for two, that's over $1000 before tip and park fees. That's approaching real money when you consider you leave over 3 tanks of gas a piece on the boat. In net outlay, that's 30% of the bill to Dive Op.(Dives are $87 for 2 tank dive) with no multi-day dive discount.
Considering that many believe this is too expensive
I say, well maybe but what are you looking for in your dive experience. Now if you leave alot of air on the boat then yes, it gets expensive. If you use all your air and you love LONG bottom times then its great. DM leave those experienced divers alone and let them enjoy the BT. I am currently corresponding with the owner of Aldora regarding the issue I posed above and hope to someday soon have options. No matter what, we all have our favorites and will continue to trade with those which we have wonderful experiences. We all, including myself, sound like were paid advertisers for our favorite Dive Ops. Now some may be, but we all just want to believe that we have found the best operator and want others to experience the same.
