I have scubapro extender watch but it didn`t have NO FLY howw can i know that and how i can do nitrox with it.

I'm not sure what model watch you have.  The best thing would be to take it to a local dive shop and see what they have to say.  I do know that in order to use a computer with Nitrox your computer has to have Nitrox settings.  If your computer doesn't have Nitrox settings you will have to buy what that does.  In order to breath Nitrox you will have to take a class first you can ask about that at the dive shop as well.

The answer is yes to your question of mixing pure O2.  You cannot, however, breath pure O2 at depth.  This can be lethal.  But mixing is known as Enriched Air Nitrox or EAN.  By adding O2 to the air, you are decreasing the amount of Nitrogen and in turn, decreases your exposure to decompression sickness (the bends).  Proper training in the area, makes it a very safe practice.

1)venturimeter and orifice are very cheap as compared to rotameter.\n2) they often don't need any calibration or maintainance once they are installed\n3) Any orifice or venturimeter can be used for measurement of any kind of flow. ( A rotameter used to measure flow of water can't be measured as it is to measure flow rate of mercury. one either needs to change the float or put the rotameter upside down and recalibrate.\n4) a rotameter can't be used for a flaow of liquid containing gas or liquid containing solid\n\nStroha

Get yourself a manual or ask someone who has used it.\n\nYou can also explore it yourself, that's the best way to learn.

There is a gadget that is made called a launch controller that is made especially for boosted and NOS cars that will get you off the line sooner. Try doing a search to see if you can find one that suites your car. You can also try finding a different gear ratio if you haven't already. Give you quicker traction. Also play around with your tire pressure as well.

Hi - I came across your insurance question and tried to email you.....also about the diving but they said your email has been 'unconfirmed' so my email wouldn't go through....you may want to check this out.  You may have to go into the email address you generated for this and acknowledge their link to confirm it so you can get emails.\n\nSo...I'm copying the email here:\n\nI don't know if this will help you at all....but at least you will have coverage...if it works.\n\n\nMy idea....if the house hasn't sold yet.  Tell the insurance company that you moved and that it is being rented.  If they need a copy of a lease... you can pick them up at any office max for $10.00.  Fake a signature...or better yet..if you have family or friends still by your old house see if they will sign the lease..just in case they need id's.  Had to do this after father-in-law passed away.  It worked.\n\nGood luck...I know it's a pain in the butt.\n\np.s.  I'm a scuba diver....but never been to N.C. to dive.  My favorite place is Curacao.  If you ever go there diving....let me know and I will tell you the best spot to stay...where you just walk down 27 steps with your gear straight into the ocean...great for new and experienced divers.  Gradually slopes from 5 feet to 200 feet.  Has overhanding cliffs to dive under and excellent for underwater photos.  Happy bubbles!!

If you have a question about the function of your dive computer, the BEST place to find an answer is the manual for that computer.\n\nAs far as I remember from the older UWATEC comp models, desat and no-fly time are displayed separately, one labelled "desat" and the other with a little aeroplane icon. But don't quote me!\n\nIf you're not sure (or the computer doesn't have a way to show no-fly time), the best is to err on the side of caution, and take desat time as your no-fly limit.\n\nMy SUUNTO computer only shows no-fly time on demand (usually around 12-16 hours after a couple of gentle recreational dives), but can take anything up to 48 hours to "desaturate" completely (which it doesn't tell me anything about).\n\nREMEMBER - your dive computer is only a tool, and doesn't actually measure anything that's going on in your body - it's making a "best guess", based on your dive profile(s) and its software.\n\nFYI: Industry standard guidelines for flying after diving:\n- after one dive in a day, wait 12 hrs minimum\n- after two dives in a day, wait 18 hrs minimum\n- after multiple dives in a day, wait 24 hrs minimum\n- after two or more days of diving, wait 24 hrs minimum\n\n- after you've done something extreme (accidentally or deliberately!), waiting significantly more than 24 hrs would be a VERY good idea

It is called "Helios" and it uses liquid oxygen, thus a larger and longer lasting supply can be carried in a smaller unit.  You can get it from your Oxygen suppiler. You will need to ask your doctor to write a prescription (he or she will be happy to).\n\nYou will be checked out by your O2 supplier company's therapist to see how well you do using a "demand" type O2 system (as opposed to a constant flow like you're probably using now).  You still will use the same delivery device you're using now, i.e., nasal cannula or mask.  The "demand" system "senses" when you inhale and delivers O2 through the nasal cannula.\n\nYou will be furnished the Helios unit and a large drum size liquid O2 storage container.  You refill the Helios unit from the storage unit, and your supplier periodically refills the storage unit.  It's all covered under your insurance the same as your other O2 supplies.\n\nSource: myself, I'm ordering one this week.  Just discussed it with the doctor.  I'm tired of lugging those bottles around and running out all the time.\n\nOh, and I believe you can also use the system 24/7, and if so, then bye-bye noisy concentrator unit!!!\n\nAlso, at usage under 4L/Min, the Helios can last 20 hours,\nand they have a travel companion available which is basically a smaller storage tank you can easily portage\nfor longer trips -- a definite desireable!\n\nHeres the website for Helios:\nhttp://www.heliosoxygen.com/index.aspx\n\nHope it works out for you!  And, me too!

I'm a Scuba instructor hope this helps...\nTwo answers....\n\nShorts are fine. I use them. Ones about knee level. They may bunch up and feel uncomfortable. Speedos or skins are very comfy.\n\nAlmost all dive courses start in a pool or shallow water. You should get a better understanding of how your ear will react in deeper water. Talk to your instructor. He has the knowledge and experience to deal with this. It is very common.\n\nEar equalization is very important in diving. If you have problems trying to equalizing on land, it may be difficult in the water. Practice before you go. Pinch the nose just enough so air doesn't escape. Blow slowly and increase the pressure. When you hear a click or a sound in your ear, it has cleared. In the water, try facing the ear that doesn't clear upwards and turn your head left and right. Remember to equalize early and often. \n\nTry swallowing. Swallow big or exaggerated. This works for some people.\n\nSome divers including myself when I'm sick use SUDAFED. It doesn't make you drowsy and one or two tabs are good for 4 hours+. I have had 100's of customers use it with no allergic reaction. To be on the safe side consult your doctor.\n\nHope this helps..Good luck!

There's a DVD called Turning Pro made by a professional diver. I got one from Extreme Sports Cafe - they have a website. Oh yeah, the film covers 3 categories of professional diving; archeaology (did I spell that right?), military diving and also deep-saturation oilfield diving which is what I think you are interested in. Good luck if you go for it... serious job, I'm thinking about it too!

you should have an oxygen dealer in your town\njust call the local health department or the local healthcare center

Just set it to field altitude when on ground. Then compare bar pressure reading on alttimeter to current pressure from weather station. If they are the same you areOK

Timothy gives good advice.  If you are mixing helium with O2, then it must come through a SCUBA shop, else you risk disaster!\n\nFor other uses, none of those gases should be restricted for sale in any way.  A welding supply would hook you up.

No exercises, (save light house hold activity and maybe a little, gentle walking)  Now is not the time to engage in cardiac rehab.  Be sure to have your nitro in your pocket all of the time.  Take the nitro with ANY chest pressure, discomfort, tightness, fullness, or shortness of breath especially associated with activity.  Do not wait for it to be "painful."  Trust me on this one.  \n\nYour condition is unknown (therefore unstable) and it is impossible (and foolish) to predict what might be the case until you have your study.  The date for your angio seems uncharacteristically far away.  Usually if a person fails an exercise test we have an angiogram done within a week and often within a couple days...even the next day.  Something seems inconsistent there.  Is the date at your convenience?  If so, have it done as soon as possible so the unknown becomes known and your cardiologist can devise a treatment plan with better information.\n\nGood luck to you.

The only way I've been able to travel with my Rx oxygen is on Continental Airlines.  They seem to be only one who accomodate you.  Even so they first require  your Dr to fill out a form prescribing the required use of O2.  \n      Then there is a fee to be paid for the use of their oxygen, ($100.) ea. way.
