i have about 40 dives and im getting nitrox certified and i want more bottom time. simple enough.
...theres no way in hell im buying a whole new set of gauges etc...
Hey everyone, im new to the board but i was jw how do i modify my setup to a 2tank rig? i know you need a manifold, 2 tanks(no shlt lol), wings, 2 regulators, and 2 bands. can someone explain this more thouroughly and give an in depth explaination? or even a link to all the items needed? A price estimate would be greatly appreciated. also, is there anyway to do this with 1 reg, 1 octo, and 1 gauge? theres no way in hell im buying a whole new set of gauges ect. thanks for your help
FYI
im about 6 ft 185
i would use 2 AL 80's. i have about 40 dives and im getting nitrox certified and i want more bottom time. simple enough.
i dive cold water by me (New York). about 55 degrees F with a 7mm single, and 5mm boots gloves and hood. i use about 18lbs
on vacation i dive a full 3mm for protection. i use about 12lbs
please help me out.
Given the OP's stated experience, I would strongly suggest that his options for increasing dive duration are....
1. Dive more, get more experience - your air consumption will decrease noticeably and you can do longer dives with your existing AL80.
2. Perfect your weighting, bouyancy, trim, finning technique and relaxation. Again, your air will last longer.
3. Get a dive computer and mulit-level your dives, to extend NDLs and decrease your gas consumption in the shallow portions.
4. Invest in a larger capacity or HP single tank initially....it is less expensive that a double set-up and will compensate with extra air, whilst you gain experience and reduce your air consumption.
5. Take a Twin-Set Familiarization, Fundies or Intro To Tech course BEFORE emptying your bank account on a set of doubles. Some money spent here will bring you new skills, knowledge and help you avoid the mistakes that so many divers make when purchasing doubles.
Don't jump straight into diving a twin-set. There are a host of new problems and dangers you can encounter with this equipment. Whilst a manifolded twin-set is 'safer' than a single cylinder - it is so only if you are capable of operating it correctly.
As you've obviously discovered, the majority opinion is that relatively new divers should not dive doubles - and many are not real nice about it.....Diving doubles is however not rocket science,....Whether you are ready does not depend strictly on number of dives,..... Way back in the day divers even learned in doubles (gasp!!).
