This may sounds crazy but 3000PSI is the same the only difference I guess that I can see for now is bouyancy rates of tanks. I plan on taking the advance courses eventually and also in future to do doubles. Just wondering what others think about and have experience with in tanks.
Thanks JEFF Castor
You'll get lots of different good advice and opinions on tanks... I'd suggest searching the gear forum.
My .02 PSI is:
*get steel. Their buoyancy characteristics make it a no brainer for cold water diving. YOu'll see a TON of aluminum 80's for sale online... there's a reason for that.
*You can get them nitrox cleaned when you purchase them. Talk to your LDS about what's necessary to KEEP them that way until you decide to do your Nitrox training
*get the largest tank you can comfortably carry. Your air consumption will improve, but unless you're really tiny and have incredible air consumption I would go with a 100 at the minimum. 100 HP's are great for doubling up... lots of folks dive double 100's around here.
*the other consideration is High Pressure or Low Pressure. If you're in a remote area with difficulty of getting access to a good shop with a good compressor go LP. You'll get better fills. I DON'T think that will be the case for you around here, so since you have access to one of the many good shops with quality (strong) compressors, I would go HP. I purchased two HP 100's as my first tanks. I loved / love them... but since diving 130's I love the extra gas, comfort margin, and bottom time they provide. I'm a big guy, so more gas is an issue. It may not be for you. (A Low Pressure 95 is about the same size and weight as High Pressure 130. For my money why carry the extra weight without getting the extra gas?!)
*If you can, try to rent or borrow before you buy to get an idea of what works for you. This is one of the few cases where procrastination will NOT be a bad thing in your life!
*Take Grateful Diver's Gas Management Class before you buy. IT is offered from time to time and will give you a fantastic "grid" through which to think about your gas consumption. It is NOT a side or minor issue! The class is usually free (though it would be worth your $$ if he charged) and one of the best 2 - 3 hour investments into your diving you'll ever make!
Good luck!
