What equipment do you need for night diving?

Posted on Oct 18, 2009 under Scuba Dive equipment | 2 Comments

I have a project for a resort management class in school and I’ve decided that I want to bring night diving into a resort that I’ve made up. But, I don’t scuba dive so I don’t know what equipment is needed. Specific names of the equipment would be very helpful because I need to find the cost for them. It would be great if you could help me out! Thanks!

I am going to guess that your resort is located on the water and in a somewhat tropical environment. There are vast possibilities for this kind of location.

The basics you will have to have are(per person) Mask, snorkel, fins, wet suits (allow for choice of short or full body), Tank, buoyancy compensator (BC), Dive regulator with reserve regulator, computer/ gauges, gloves, weight belt, knife, dive booties, Main light, back up light, glow sticks.

You will need at least 2 master divers to do this. Offer it from the shore line, instead of from a boat. I would also go all out and for safety use a Electronic Rescue and Locating System http://www.diverrescue.com/ you loose one person and the resort could fold.

Think about underwater man made and placed items to dive on. A sunken ship, man made reef, art, ect. Have seasonal night dives. Example Halloween place spooky Items around underwater, Christmas would be Christmas themes. There is ans are low power (12 volt dc) that will work underwater. A scavenger hunt.

There are so many possibilities, hove fun and good luck. I love this kind of projects in class.

Basic advice for a scuba/snorkeling dummy??

Posted on Oct 18, 2009 under Scuba Fins | 2 Comments

Hey now!

I’m just getting into snorkeling and scuba diving and want to get a really good mask/snorkel/fins to begin with. Unfortunately, I do not live anywhere close to a dive shop and have to order these items online. The store has said not to worry about sizes, as I can send back and exchange sizes at no charge to myself (which is really rare and nice of them). But I am not sure which brand or model to go with, especially for fins.

What would you consider to be the very best set of fins, if money was not an issue? Atomic? Mares? Should I get split fins?

Do dry snorkels really work? Do they close when submerged? If you have a good dry snorkel what brand did you get?

Thanks a bunch. Any extra advice or abuse you want to include for a rookie scuba diver/snorkeler would be appreciated. I will be taking a PADI or NAUI course in the winter on vacation, but wanted to practice snorkeling all summer and fall.
I’m not really getting much in the way of advice from the dive shop. They just want to know what I’d like to order. Some people prefer open heeled, some split fin, some like longer ones, etc. I’m sort of trying to get a grasp of which fins experienced divers seem to gravitate towards as they begin to dive more. If you can’t suggest a brand/model you like, can you at least tell me what you didn’t like about a particular pair then?
I will be swimming in tropical and cold water, and will pick up some neophrene boots, so I can narrow it down to open heeled fins. The fin selection is actually the choice I am most unsure about. The dive shop is going to let me buy 3 or 4 masks and let me keep the one I like and use the refund towards my fins, snorkel, PADI training, etc…

I dive the Apollo BioFin Pro. I love them. My husband dives Mares Volos and does alright with them. It sort of depends on your diving style. I like the split fins because they give power/propulsion on both the up-kick and down-kick. That means I don’t have to work as hard, and can easily keep up with any other diver in the group. If you are already a strong swimmer, like my husband, you’d probably do fine with a traditional fin.

Fins also have different buoyancy ratings. I wanted a fin that is negatively buoyant, because I have a tendency to be naturally buoyant and don’t need any extra help there. My husband likes the idea of a fin that would float in case he ever drops it. So, you might want to consider that too.

Do most scuba divers pee in their wetsuits while diving?

Posted on Oct 18, 2009 under Scuba Wetsuits | 7 Comments

During my open water course, our instructors all told us that they sometimes pee in their wetsuits while diving.

They said it’s ok to do this in your own wetsuit, but not in hire suit.

Do most divers pee in their wetsuits whilst diving?

These things just aren’t mentioned in the PADI books.
Carl: people don’t wear wetsuits in pools (exception: during first stage of Open Water training).

The saying goes, "There are those that pee in their wetsuits, and those that lie about it."

1. If you are healthy, your urine is sterile when it exits your body. While the urine smells, it technically isn’t bad for you to come in contact with it.

2. Regarding sharks, yes, they can detect the blood/urine/bodily fluid in the water. Just because they can detect it, doesn’t mean that it will trigger anything in them. Humans are not on a shark’s menu. Now if you are dumping tuna fluids or seal fluids, I’d be worried. The anology that I like is if you smell a skunk on the side of the road, does that trigger you to be hungry for a hamburger?

3. In cooler water, many believe that peeing in the wetsuit helps them stay warm. It is a fine balance if it helps or not. First, you are expelling mass from your body which no longer has to be warmed. This is a good thing. However, most people when they pee in their wetsuit will "flush" it underwater. With the new water coming into the suit, your body has to work hard warming that water.

4. Never pee in a rental suit. Would you want to use a wetsuit that someone else peed in? It is a courtesy thing.

5. It is important to stay well hydrated before and after your dives. Dehydration is a major contributing factor to decompression sickness. Ok, so here you are being well hydrated. I think it is related to the submersion reflex, but the moment you hit the water, you have to pee. Holding it can cause more problems then just going in the wetsuit.

average Scuba gear coast?

Posted on Oct 18, 2009 under Scuba Gear | 1 Comment

What would be an average price for all the Scuba Gear (not top of the line but decent and safe) that I would need to dive in Florida and places around there and what gear would that be? Thanks

You can find good used gear at dive shops. Many will have consignment gear on hand. Call around and see what they have. Most shops will provide a warranty on used gear if you pay to have them service it for you.

If you buy used gear on Craigslist, you have to be cautious. Most people buy all the gear, dive on one trip then give it up. They intend on diving again, but never get around to it. By the time they try to sell their gear, it’s been sitting in their garage for 10 years. The seals are all bad, nothing works right and they don’t even know it. Plus, the gear is outdated by 10 years!

You can get outfitted completely for about $1500 for all new gear. Upgrade to a better dive computer and the price can easily go up to $2000.

Check out the prices for new gear online at leisurepro.com, diversdirect.com etc. Once you have these prices in hand (depends alot on where you plan to dive) you can compare prices locally.

Just don’t expect to buy something online and have a local dive shop help you out if you have problems or issues. If you buy from your local dive shop, they’ll help you out if the gear isn’t 100%.

Can you purchase Scuba diving equipment for your own use?

Posted on Oct 16, 2009 under Scuba Dive equipment | 3 Comments

I was wondering if i could buy all of the Scuba Diving equipment for my own use? Do you need a permit? etc?

Yep, you could actually. You could buy just about anything to do with scuba other than a rebreather rig. The kicker is, to use any of it, you need a C card to fill a tank. All those thousands of dollars you spent on gear is pretty pointless unless you can use it with a 10 dollar air fill. No shop will fill a tank without knowing you are a certified diver. The profit simply isn’t worth the liability.That simple and a very good control measure. It’s worked for years. Greed in this case works well. It costs more to deal with litigation than to skip a C card check.

I don’t know what type of SCUBA gear bag to get.?

Posted on Oct 16, 2009 under Scuba Fins | 2 Comments

I need a scuba bag that can hold my snorkel, mask, booties, fins, and wetsuit. Also it needs to be kind of cheap like less than $50 preferably.

You can usually hunt around and find a wheeled hockey gear bag in sports stores. They’re cheaper ( by about 200 bucks) than most of the Armour Dive gear bags and hold about the same volume and it’s in your price range.

In scuba diving what keeps the pressurized air from becoming too cold to breathe?

Posted on Oct 16, 2009 under Scuba Regulator | 2 Comments

I know that scuba tanks are pressurized to 3000 psi. This is then released by the regulator to a pressure close to the water pressure for breathing. Now refrigeration works by pressurizing a gas, letting it cool down to ambient temperature, and then decompressing it. In the decompression it gets colder. How come the 3000 psi air inside the scuba tank, the pressure used to cool the atmosphere into liquid nitrogen, is not too cold to breathe on decompression?

When you take a breathe from your tank, the high pressure air is converted to medium pressure by the first stage of your regulator (the bit that fits on the tank). The mouth piece transfers this air to your mouth at ambient pressure. If the high pressure air came straight into your mouth, it’d blow your ‘ead off(ish). If you open the valve on a tank (check with the staff that you can waste a tank) fully and leave it to empty a 3000psi tank, once it’s near empty, feel the valve, you’ll find it’s pretty bloody cold, so you’re kinda right that when gases go from high pressure to low pressure (according to Charles’ law:at a constant pressure, the volume occupied by a given quantity of gas decreases as the temperature of the gas decreases (p1v1/t1=p2v2/t2) but the volume of the tank remains unchanged, the temp decreases.
