What side does the octopus go on? left or right?
The reason to have it on the right is because that is "standard". I dive with a long hose (7') and an octo around my neck on a 22" hose. So long as you explain it to anybody you dive with and talk about your plan for air sharing in advance, it shouldn't be an issue.

I am downloading for the
It sounds like it is full and can only hold so much information in the watch. Upload the contents to the computer and then delete whatever is on the watch to start again. You can replace the info on your most current dives after you save a copy in your pc. Deleting the contents of the watch should enable you to enter information in all available prompts on the pc ect. Once the watch approaches the limit of how much information can be stored in it ect., it starts to act funny and it blocks access to info at will. Deleting what has been entered to clear space should solve the problem. If clearing the info stored in the watch does not solve the problem then I would suggest taking it to a professional for repair.
On a recent trip I lost my purge value from my bo...
Purge valves are fairly generic. If you can't easily locate a Aeris dealer, go into any SCUBA shop and ask if they have replacement
purge valves. They do come in several valve and nipple sizes, but you might get lucky. Any dive store worth it's salt will have spares of that sort as a customer service. Failing that, just call the company, talk to customer service and they will likely send you one for free.
Scuba Tank Setup Question
Ideally, you should have someone who is certified in regulator servicing to do this for you. Otherwise, you may be endangering your life.

How exactly do snorkels work when you are under the water???
Or more to the point: Snorkels don't work under water. They work on the surface by allowing the wearer to have his/her face in the water so that one can look at what is going on and the top of the snorkel is several inches above the surface allowing the user to breath through the tube. If, as often happens, the snorkel gets water in it, there is a trap at the bottom that catches it so you don't **** it into your lungs and on the next exhale you do so forcefully and this expels all the water from the tube and allows you to continue breathing.
Aeris XR-1 Dive Computer in console/w compass boot
it is simply housed in a rubber housing. it is an air integrated computer so the hose will connect to the computer through the bottom. Just peel the rubber housing back away from the face and pop it out the front.

The right snorkel for me
"A snorkel must fit comfortably in your mouth, allow you to purge water out of the mouthpiece and hose quickly and help you to swim efficiently. But, the most important characteristics to remember when choosing a snorkel are its length and the diameter of its barrel.
Snorkels must not be too long or too short. If a snorkel is too long it will be difficult to breathe because the barrel will fill up with carbon dioxide. Every time you breathe out carbon dioxide through your snorkel your breath must travel up and out of the barrel of your snorkel to allow you to draw oxygen back down the barrel and into your lungs. If your snorkel is too long you will only push a percentage of the carbon dioxide up and out of the barrel during your exhale. You will need to inhale oxygen before all the carbon dioxide has been pushed out; leaving the percentage of carbon dioxide entering your bloodstream higher each time you take a breath. This cycle could lead to suffocation. If a snorkel is too short it will constantly fill with water, requiring you to constantly force the water out of your snorkel which can be very exhausting.
The inside diameter of your snorkel must be approximately three quarters of an inch or 1.9 cm. If the snorkel is thinner than .75 inches it will be difficult to breathe because there will not be enough room in the barrel for you to draw enough air into your lungs. This will cause you to breathe harder and rapidly, which could cause hyperventilation. If the barrel is thicker than .75 inches it will be too large and will be uncomfortable to use and attach to your mask.
Learning to attach your snorkel to your scuba mask to make sure it is easy to grab and use is an important part of safe scuba diving practices. Snorkels are attached to the left side of your mask with a snorkel keeper. Snorkel keepers are either plastic or rubber and most use a post-hole closure. Each snorkel keeper is different and attaching your snorkel to your mask with a snorkel keeper requires practice. If you will detach your snorkel from your mask after each dive you should practice attaching your snorkel, as it can be a little tricky. Alternately, you can leave your snorkel attached to your mask if you are diving more than once in a day.

What is the best way to clean your mask and snorkel after a trip in saltwater?
No need to use soap or fancy cleaners for snorkel or dive gear. The important thing is just to get the salt off, and plain old fresh water will do the trick.
The best way to clean your gear, is to fill a bucket or a tub with warm water, and then dunk your gear several times to rinse it out thoroughly. In some cases I like to swish it around underwater, and maybe rub the rubber parts to ensure a thorough rinsing. After that, let it drip dry and store it in a cool, dry, *dark* place.
Salt and sunlight are the two things that'll kill your gear in no time at all, keep it safe from that and it should provide good use for a long time.
Why do they put the scuba tank in water while refilling it??
A scuba tank is design to hold a certain volume of air, at a particular at a particular temperature. In the US, the standard tank is an aluminum 80 CF tank. At room temperature and 3,000 psi, the tank holds 72 CF of air (yeah, I know they round up calling it 80 CF tank).
When you are filling the tank, the air and tank will become warm/hot. If you check the pressure guage while the tank is warm, it will give you a reading of X. Once the tank cools, it will give you a reading that is less than X. They put the tanks in the water in the hopes of keeping the temperature do, and filling the tanks closer to the design pressure and temperature.
Some examples that you can see...
In Mexico, many of the tanks will be sitting in the sun while on the boat. The tank may have a reading of 3,200 psi. Once you jump in the water, and the tank cools down, the new reading may be 2,800 psi without ever breathing any of the air.
I have been ice diving, the tank was acutally colder than the water. Since the water temperature was warmer than the tank, me pressure reading was slightly higher.
What is the maximum time you can get out of a scuba tank?
There are four main variables affecting this:
1. The (total) internal volume of the tank(s)
2. The pressure to which that tank has been filled
3. The ambient pressure at depth
4. The rate at which the diver uses the air out of that tank for their breathing and buoyancy control (including drysuit inflation).
The first three are simply a matter of physics and will be the same for everyone under the same circumstances.
The major variation comes from the last one, which is usually a function of the diver's experience/ competence (not the same thing!). One who is less so will go through air quicker than one who is more so.
So the best answer for your question is "It depends..."!
However, many resorts and guides set a maximum dive time of one hour, so they know when to expect a diver back on the boat (or, when they have to call out the Coastguard!). This might be the source of your friend's assertion.
FYI: The current world record for breathing off a single tank of air while sitting at the bottom of a swimming pool is a little bit short of 8 hours. The divers in question were using 12-litre cylinders charged to 200B and breathing verrrry slowly! (approximately 12 x 200 litres / 460 minutes = 5.22 l/min)
What is the proper way to install a valve into a scuba tank?
Any preesurised gas container should be visually inspected annually (at least) and pressure tested every 5 years, 3 years or annually according to local law.
If you are going to have it tested, screw the valve in loosely as they will need to examine the threads on it in order to pass the tank and valve as a unit.
BUT ALL THAT ASIDE, the answer to your original question is: Replace the tank neck O-ring, very lightly lube the threads of the valve with a SCUBA silicon grease, wind the valve in to finger tight (if you have a torque wrench you could find out setting) if no torque wrench, nip the valve tight with a light tap from a rubber mallet on a 12" wrench (I know it is a bit approximate, but the O-ring makes the seal, not the tightness)
Scuba HP pressure gauge has air bubble inside. Can I fill with kerosine?
Pressure gauges are sealed and should not ever get bubbles in them. If there's air in the gauge, there's some possibility the Bourdon tube has a crack in it.
You will spend more time dinking around with getting a bubble out and resealing the gauge than the instrument is worth. The pressure gauges on a fill station are industry standard parts and you can buy replacements off the shelf. They're not terribly expensive. Replace it.
Scuba octopus?
An octo IS a regulator. There are two types or regulators on a typical scuba rig. Your first stage reg that is attached to your tank valve. From this first stage, there are hoses leading to your primary breathing second stage reg and your Octo second stage. The job of the first stage is to bring that possibly 3,000 psi air in the tank, down to a more reasonable pressure of about 150 psi. From there, the air goes to the second stages and can be reduced down further by these second stage, on demand (meaning it delivers air when you inhale and stops when you finnish inhaling), regs.
The Octo is a second stage back up for a buddy that is out of air or if your own primary second stage ( the one you normally breathe from) is no longer functioning. Octos are generally ( not always) a cheaper reg, that may not have all the bells and whistles that a primary air source does. It's there for an emergency, so ease of breathing under load and tuning adjustments are minor. It gives you air when you're in a pinch, thats the important thing.
