TDI vs IANTD

Tek, the first thing that would convince anyone that you have maturity is for you to change your tune and start talking about reasonable goals and baby steps.

FYI, you don't need a double bladder with a drysuit. You'd freeze your azz off at 400 feet even in a place like Cozumel without a drysuit.

I personally don't see any need for 2 deco gasses on 150 foot dives.

Having enough gas to deco on in the event of one deco tank failure seems like a pretty good reason to me

Having a double bladder is a good idea when diving wetsuit, but for those ppl who dont have the money to have 2 different bladders, then go with one that you can use with both. Its not that you cant use a double bladder with a drysuit its that .0001 percent u would ever use it, .

Reasonable goals, Dreams, Goals are never reasonable, becuase its life and you never no wat is resonable in this world. If i have a goal. im gunna set it high, i dont execpet failing. Its the job i have to make this way, but i will succeed. I thought that i would never beable to aford the OW class, but now, i have doubles, lights, rregs, all over the place.

Not enough of it .We were using Al 80 doubles (Caribbean). Backgas deco would have required 177 cu ft. Adding the second deco tank allowed for 1 failure. And using 2 deco tanks in a controlled (course) environment was a good experience for me.

Why wear a wetsuit at all? Just wear a drysuit with the right thermals underneath..

My goal is to check my spelling and grammar before sending out a message.

I dive as part of a team so we account for the loss of 1 deco bottle and on most dives and carry AL 80 bottles of 50%. We also limit the BT on dives in the 130-150 range to avoid being stupefied by narcosis on air or lean Nitrox. There is certainly nothing wrong with learning how to use 2 bottles on experience dives.

That's the most unreasonable - bordering on unintelligble - thing I've read in years. A reasonable goal for you would be to learn basic gas management and plan and manage a dive on a single tank while reserving enough air to get you and your buddy to the surface in an emergency.
