I just purchased a new s40 tank and k valve for my daughter, received

These are my first underwater photos, but there are a few nice ones.

   Ugh, it's been four days since my first lesson (Thursday 12) and my ears
still feel funny.  It's the same problem, I open my mouth up wide or swallow
and I hear small popping/cracking in my ears. I'm starting to wonder if I
should go to my second lesson this Thursday.  I hear ...

I've heard mention of a 232? bar being adaptable to a k fitting
adapter and the larger 320 ? bar not being able to accept the adapter.
I'm looking at a pst 100 tank at divers direct and he mentioned something
about the valve, i think he said the adapter was in the valve already ?

Hey All,
I'm looking to get certified in San Clemente, CA. I have 7 other
co-workers that want to get certified also, but some of them are
telling me there are sometimes 2 for 1 specials at dive shops around

   Question: is it hard to be certified as a PADI instructor?  How many

Can any one tell me the average water density of the caribean,
mediterranean, red , black and dead sea ? in metric system please if
possible.
Thanks,

I've noticed a lot of DIN valves on the HP steel tanks, is this valve

Hello. This is my first post in here.. i hope i don't end up on a few dozen
spammers lists. ;-)
I have recently pulled out my dive gear after a 14 year hiatus and much to
my surprise, my Suunto dive computer still works good as new. I took it out

Does anyone know what effect a long term exposure to helium will have on a
O2 sensor? Is there any change in sensor drift?

Our dive group is heading down to Dutch Springs this coming weekend.  
I don't see much discussion here about the place and I wonder if
anyone has any information to share.  
thanks

I am planning to visit southern California, specifically Catalina
Island, at the end of Aug, and have hooked up with Scuba Luv on the
island, for two days of diving. I plan on renting a 7/5, possibly to
wear over my 3mil full. I am also bringing a 7m hood and 5m gloves.
