Unfortunately it boils down to you being a new diver and haven't had a lot of exposure to equipment.
Despite what you may read on here most of the gear is personal choice. Sure there are 101 different ways to configure your gear, you'll get testimonials swearing by this reg, or that one...
Prosecutor asking the cylinder manufacture:
"What does the stamp on the cylinder that says 3,000 mean"
Manufacture responds:
"That is the maxium operating fill pressure."
Prosecutor:
"And who sets those standards?"
Manufacturer:
"The US Department of transportaion".
Prosecutor:
"and why...
Not to hijack or detract from this post, or the specific topic....hope I'm not.
I recently completed the Handicap Scuba Associations Instructor crossover course. It was a very illuminating and eye opening course - I'm glad I took it.
That said, it was lacking in the main reason I took the...
I'm going to throw my 2 cents in here at the risk of being lynched but I think it needs to be said.
Learning to dive on the INTERNET is a BAD IDEA.
Expanding your knowledge or getting differing views is a GOOD IDEA.
Based on all I've read here, and the questions you are asking, you are...
Well said.
Love the technical explanations in the responses.
KISS - Keep it stupid simple. (gentler version than 'keep it simple stupid').
Don't hold your breath :-) Makes it simple and easy for the average person and recreational diver.
Thalassmania is correct.
Sharks do not have "swim bladders". They swim, the fins do provide lift, otherwise they'd sink.
I misspoke on by bladder comment.
Thanks for the correction Thalassmania.
I would say the same. You are entitled to your opinion as I am mine.
It is wrong to tell someone to break a rule - period. The rules are in place for safety.
The operating pressure is physically stamped on the tank. That is the limit of the pressure for general use.
Breaking the rules...
1) Go to the bottom - As long as air pressure and depth isn't an issue.
2) Use topography and features to your advantage - Do #1 and back up against something, take away part of the 360 environment you're in (angle of attacks). I know of no documented cases where sharks attack 'downward', they...
.....my effort at simplyfing this....
Picture 10 blocks in a horizontal row.
These blocks represent the air, or any other gas you breathe.
For simplicity sake and to make it easier to visualize, my example won't be 100% correct in the breakdown, let's assume you are breathing 2 blocks of...
I chose NAUI originally because it required more of me.
I stayed with NAUI becuase as an Instructor I am free to alter and make the course my own as long as it meets or exceeds the standards. I could make the course as "hard" or "soft" as I wanted to.
I can spend extra time on any subject I...
Most of what I've read is great advice to your questions; I didn't read every response tho.
The #1 and #2 rule in diving is - Comfort & Fit.
I guess it boils down to what you're comfortable with. Knowing your configuration helps with this; steel vs. AL.
My preference, as well as some of...
I think I started something...
Any Professional that gives advice or an answer, that is contrary to his or her certifying agency, the manufacture of the product, local, state or federal law is wrong.
My initial comment was to express my public dissapointment with people who have a...
I never claimed to always be able to give the right answer.
If someone asks me a question and I don't know, I say I don't know.
It's no different than walking up to a Policeman in uniform and point blank asking - "Officer can I go 60mph in a 50mph zone?".
The policeman will give you the...
Ok, you two aren't getting it.
All I am saying is NO dive professional should EVER give any advice contrary to the Law, Regulations or Standards of their agency.
Giving any person the advice, as a Dive Professional, is WRONG and it's really not debatable. It's a fact. If any...
I've never been one to mix words.
The Department of Transportation sets the rules and regulations for scuba cylinders.
You can do as you please and ignore the law if you choose to do so, it is your right.
No Dive Professional should ever give any advice to break any rule or regulation -...
First, don't follow the above guy's advice. It's bad, bad conservation and not an appropriate attitude to keep enjoying the enviroment.
1) Visit your states division of fish and wildlife. It lists seasons, length/size limitations and the legal way to kill something. These law's vary from...
Your Instructor will most likely cover this with you, I wouldn't worry too much about it.
You could always use a clip type bungy and put the bungy around the bag and then clip it to your BC.
I carry mine in my drysuit pocket...not an issue for me.
Ask your Instructor, it should be part...
