How many tanks can you have for scuba diving?
Hi. I’ve heard rumors that people have had 3 or 4 oxygen tanks for scuba diving. Is this possible if you have the right regulator? Also, if it is, does that mean that it will be increased duration?
Theoretically, you can take as many tanks as you can carry. Recreational divers normally just use a single back-mounted tank for the entire dive.
Technical divers may carry multiple tanks for a number of reasons. A typical configuration for tech dives is to have two tanks mounted on their backs (“doubles”), connected to each other through a specialized valve mechanism called a manifold. The two manifold posts each have a separate regulator mounted to it, and there are isolator valves on each post as well as in between tanks so that the air flow can be cut off at these locations in case of equipment failure. Normally the diver has access to the gas in both tanks through either regulator, so the two tanks are used to increase the total gas supply for the main portion of the dive. The gas used for deep dives is usually something called trimix, which is a mixture of oxygen, nitrogen, and helium and will be used during the deepest portion of the dive.
The tech diver may carry other tanks than just their back-mounted doubles, each with its own separate regulator. They may have one or more tanks filled with “traveling” gas, which they breathe from during the ascent & descent portion of the dive because the bottom mix in their doubles may not contain enough oxygen to maintain consciousness at shallower depths. Finally they may carry one or more “deco” tanks which contain high levels of oxygen (50% to 100%) which are only used at very shallow depths to reduce the amount of time spent decompressing at the end of the dive.
A typical tech diver configuration for a deep dive will be a set of doubles containing trimix (each containing around 100 cubic feet of compressed gas) plus smaller sling-mounted tanks containing a travel gas and a deco gas. They may also bring other tanks along, either to increase the duration of the deep portion of the dive or to use “better” oxygen mixtures at different depths of the dive.

When is the best time buy wetsuits?
I am planning to buy wetsuits (both winter and spring wetsuits). I would most likely wear them during the fall, winter, spring months. I live in Southern California and people have told me that wetsuits are on sale during the summer since most people don’t use them during that time because they would rather go shirtless. Is this true? Or are people more likely to buy wetsuits during the summer because that is the only time they are willing to go in the water?
Summer is the best season if you want to save your money

What type of wetsuit do I need to buy to compete in the Chicago Triathlon on August 29, 2010?
I see a lot of people wearing shorties or 3/4 types in last year’s photos, but I wonder if I could get away with a full suit – then I could wear it in a wider range of water temps. Any thoughts? Does anyone know what the water temp is in Lake Michigan that time of year?
you should try to demo a few suits or borrow a friends to try out before you buy. tri wetsuits are expensive and you don’t want to be stuck with something you don’t like. many times people will prefer sleeveless because it makes them feel less claustrophobic.

Wetsuits how to choose – Wetsuits
How should I choose a wetsuit?
I want to buy a wetsuit. I’m 5″2′ and 108 lb. Would you give me advice what kind of things I have to check when I buy my first wetsuit?
Any good brand? How think should it be? What kind of material? etc…
Also, do you know any good store to buy wetsuit near UCLA and Burbank?
Which store has many selection of wetsuits? I am looking for a surfstore in West LA or Burbank area.
This is for surfing in LA beach.
There are a few things to consider. As far as general fit goes, you want it to be snug, but not so tight that you are having a hard time breathing or moving. Try it on and do movements that you would when you are doing the activity you want it for. Ex- surfing. Move your arms like you are paddling, squat down and stand up, just move and make sure there aren’t restrictions.
Look at the features that it has. ie warmth, flexibility, blindstitched seams, etc.
- Type of suit. A spring suit has short sleeves and short legs. A full suit has long arms and long legs. Then there are some that are combined- short arms, long legs; long arms, short legs.. only a wetsuit top..
I would say just get a full suit. This is generally what you will see and is the most popular.
- Thickness. The wetsuit thickness is in millimeters. 3/2 for example, means 3mm in the body portion, and 2 millimeters for your arms and legs. This is a good thickness for 60 degrees and above. I get cold easily so I wear a 4/3 for anything under 65 degrees.
-Flexibility. For me, this is one of the most important features. If you want it for surfing, you are going to be paddling A LOT, so you want little or no restriction in your shoulders. You also want to be able to bend forward and move your legs easily.
- Seams. This is where the wetsuit is sewn together. The fewer the seams, the less chance you have of water leaking in, or having the wetsuit come apart from wear and tear. Some have glued seams, where they sew it together, but have a “reinforcement strip” along the seam as well so water doesn’t leak through. The idea is the fewer the seams, the warmer the wetsuit. Not really the key factor in warmth though…. so don’t worry too much about this.
And then there are going to be extra features that the wetsuit may include. Rip Curl always has 50 features for each wetsuit. Ex. Batwing, zipperless, fireskin, hydrophobic material, seamless shoulder panel, hydrolock collar, etc. Read the little booklet and decide which features you want and what’s just extra money. For me, flexibility and warmth are the most important, and things like zipperless and an extra collar are just extra features that are unnecessary. Talk to the sale people too.
I like Ripcurl. Xcel is great too.. Quiksilver great also.. Try different brands on because they will all fit a little differently even if they are the same size. Find the company that fits the best. MAKE SURE IT’S NOT TOO LOSE OR YOU WILL GET COLD. So finding the right fit is key.
Lastly, try getting last year’s model to save some money…

Where to find competitive diving suits online?
I am a competitive diver and recently just competed in atlantics. The girls from ontario and quebec had these really nice, cool looking bathing suits (brand names rally, tornado). I looked online and I can’t seem to find anything that looks like them.
Any places you know that would carry these type of suits?
www.swimoutlet.com is usually the most competitive from what I’ve seen. But if you don’t like their pricing, do a yahoo shopping search for the suit you want

Drysuit vs Wetsuit for SCUBA diving?
I’ve been SCUBA diving for 14 years in Southern California. The water I dive in rarley gets below 50F. I’ve always used 7mm wetsuits and never had a problem with temperature. The only problem I have is I hate squeezing into a wetsuit. It is so frustrating and a pain in the ass. Part of the problem is my weight fluctuation. It changes about 30lbs up then down then up again. Even with a larger suit it is hard getting into it. I’ve been think of a drysuit since they seem to be much easier to get in and out of and seem more forgiving of weight change since the sizing ranges 30lbs for one size.
Are there any other negatives to a drysuit I’m not seeing? Other than cost. I’m ready to spend money if it mean more comfort.
I personally find that getting into my dry suit(s) requires much more effort than getting into a wetsuit. A dry suit is worth the effort for the extra comfort especially when spending long periods in cold water, but my experience has been that a wetsuit is easier to get on and off.
Most dry suits are cut much more loosely than a wetsuit, which would certainly be the case if you are trying to accommodate a big swing in weight. The looser the suit, the bulkier you will be in the water (even after squeezing out excess air) and the creases/folds will generate a noticeable increase in drag compared to a smooth wetsuit. On the other hand, trying to reduce drag by improving the fit of the suit will result in restricted mobility especially with a laminate shell suit since the suit itself does not stretch. Reaching your arms above your head or touching your toes, while easy in a wetsuit, may be somewhat difficult in a dry suit.
Not only is the initial investment in a dry suit significantly more expensive than a wetsuit, but dry suit care is also more complicated. Dry suits have valves that need to be maintained, and latex neck and wrist seals will need to be replaced every couple of years on average as the latex stretches out over time and loses its ability to keep a tight seal. Dry gloves (a surprisingly expensive option) can help extend the life of wrist seals but not much can be done except replace a leaky neck seal. Latex is also damaged relatively easily so a nick or tear will also result in a leaky seal that will have to be replaced. Many suits today have soft socks with removable boots, and the thin material of the socks is also a common place for leaks to develop. Leaks in the suit shell can be field repaired with a waterproof sealant such as Aquaseal, but locating the source of the leak can often be a challenge.
There are more and more dry suits on the market nowadays that permit self-donning, but if you buy one with the traditional zipper across the back you will also be dependent upon a buddy to help zip you in and out of the suit. It doesn’t sound like such a big deal until you are in a rush to get to the restroom after a dive. :-) A significant part of that problem can be solved with a P-valve, but that also involves additional expense, maintenance, and effort to ensure proper operation.
So a dry suit isn’t all grins & giggles. I wouldn’t advise investing in a dry suit without trying one first to verify that it really solves the problem you perceive with getting in & out of a wetsuit. Both DUI and White’s have a traveling demo trailer that stops in a variety of locations around the USA, if you are close by to one of these demo locations I would recommend that you check it out before making a decision. The White’s Fusion suit may be of particular interest to you, it solves some of the dry suit fit problems with bulkiness and mobility that I mentioned above. If this is not a convenient option, check with a local dive shop to see if they have any demo suits that you could try.
White’s Fusion Demo dates: http://www.whitesdiving.com/sport-diving/events
DUI Dog Days dates: http://www.dui-online.com/2011_rally_participating.asp
Good luck with your decision.

Navy SEAL scuba diving equipment?
I was watching this thing on Navy SEAL training and when they finished diving with regular equipment they used these things called drakkers or draggers or something insted of regular tanks. I’m just wondering what they actuall are. In the show the instuctor said they weren’t as safe because they could actually let water in them and if you breathed it in it was like swallowing acid. Also they are kind of square and not as long as a regular scuba tank. Hope that information helps you answer my question(Which by the ways if I wasn’t clear was what re they actually called and how are they better or worse?)
Thank you :)
I think you are talking about a dragger re breather, re breathers preceded open circuit scuba by several years and I believe were used in the second world war, these were oxygen based re breathers and are actually extremely dangerous to use below a depth of about 30ft or six meters oxygen becomes toxic at highish partial pressures 0.6 bar PP is generally the limit set for the use of oxygen as a decompression gas by military and technical divers. modern re breathers are very safe to use with the proper training and experience all diving Equipment is. It is designed for “down stream fail safe” which means if it fails it will fail delivering the breathing gas and “free flowing” all divers are trained to breath from a free flowing gas source. A water leak into a regulator generally is not a serious problem again all divers are trained to “breath past” a small amount of water in the regulator or mouth. should you have a major water leak into a regulator you would simply change to your alternate air source or “octopus rig” or that of one of your dive buddies. with a lot of these “shows” about diving it is quite often said that the breathing gas is oxygen. Oxygen is never used as a breathing gas by divers except in special and exceptional circumstances where it is used as a decompression gas after a very deep dive by military or technical divers. Pure oxygen is never breathed below six meters, a deep dive would be any dive of over 40 meters or about 120ft. an example would be the Lusitania of County Cork in Ireland the wreck lies at a depth of 90msw using special decompression schedules the ascent from this wreck takes about six hours! using open circuit scuba and a last deco stop of two hours at a depth of six meters breathing pure oxygen after a 20 min bottom time. The ascent time would be considerably shorter apparently using semi closed circuit re breathers such as the dragger unit.
Semi closed and closed circuit rebreathers certainly make deep diving easier but as to which is best I think it comes down to personal preferance, I cant see the point in using a rebreather for a 20 minute dive at a depth of 20 meters or sixty feet open circuit scuba is fine for this using compressed air as a breathing gas or posibly nitrox if you want to increase yor bottom time a little.

what to prepare for an open water diving course?
I’m finally going ahead with an open diving course in Tioman Malaysia. it’s expected to be sunny and i get sun burnt easily. what are some basic items to bring on the boat with me?
I’ve never been diving in Malaysia, so I can only offer advice for boat diving in general.
Obviously if you burn easily you should bring some form of protection from the sun. If you use sunscreen, try to use one that is environmentally friendly. A cap or hat may provide some protection for your face and neck, that is an area that gets a lot of sun. Sunglasses will help protect your eyes.
If you are prone to seasickness, take any medications a good hour before boarding the boat. Over the counter medications such as Dramamine and Bonine are fine as long as they don’t cause drowsiness. Test the effects of the medication in advance so you know what to use for diving.
Only bring on the boat what you need to have. Space is usually limited, so pack small.
Much else depends on the boat and the dive operation:
….The boat may or may not have a canopy. If so, that will help some with your sunburn concerns.
….There may or may not be a dry area on the boat. If not, anything on the boat (including clothes, towels, etc) will get wet, so a small/medium sized dry bag would be a good investment.
….Along with a dry bag, something to protect small or fragile items (like sunglasses, watches, jewelry, etc) is worthwhile. Many divers find a hard mask case useful for this purpose.
….There probably will be drinking water on board, but until you know for sure consider bringing a bottle of water along.
….There may or may not be snacks for between dives. Hard candy like Jolly Ranchers can help with the dry mouth that results from breathing dry compressed air.
….A light windbreaker can be useful for the boat ride back after diving. Depending on the weather and the speed of the boat, the ride back can sometimes be chilly especially if it is raining.
That’s about all I can think of off the top of my head. Have a great time!
