What's key to finding that perfect snorkel? Most likely, it takes a profound understanding of the basic components at work with the device that allows for efficient breathing in the conduct of skin diving or snorkel diving. If you're mind is all set on the snorkel's mechanism, testing different snorkel types to end with the purchase of a good one can therefore be completed in a jiffy. In this article, the SK-201 Reflect-Dry Pro II snorkel is presented as a fine example of how a semi-dry snorkel works and why this may just be the right one for you; given the set of features discussed in the proceeding paragraphs.
How a Semi-Dry Snorkel Keeps Water Out. The SK-201 Reflect-Dry Snorkel is a semi-dry type of snorkel that is engineered to be water-resistant out of the box. On the top end of this snorkel is a wave deflector that simply reduces the potential seepage of seawater towards the barrel - just in case the user overlooks his depth position on the water. Meanwhile, its contoured barrel averts the flow of seawater seeping through the mouthpiece and redirects it to the purge valve for easy clearing.
Comfortable Breathing through the Semi-Dry Snorkel. What's good about this semi-dry snorkel is that it allows an optimal volume of air to permeate the barrel and flow into the mouthpiece with minimal chances of engulfing seawater while breathing through the snorkel. Along with its contoured barrel, the snorkel is outfitted with a flexible silicone tube that can easily be adjusted to suit a more comfortable position. The length and diameter of its tubing is also configured with specifications that would allow for the least inhalation effort.
Why Silicone is an Ideal Component? The suitability of silicone as a mouthpiece component is greatly emphasized with the SK-201 Reflect-Dry Snorkel. Apart from its water-resistant nature, the soft material also allows for a comfortable bite to therefore reduce instances of jaw fatigue when snorkeling. Silicone is also known to be low-maintenance which could therefore last you many years of snorkeling fun. Designed with high-quality materials and constructed for efficient performance, the SK-201 Reflect-Dry Snorkel is a great scuba gear to accompany the snorkeling fanatic or the avid scuba diver. With this semi-dry snorkel, the excellent features of both the basic snorkel and dry snorkel is truly at your disposal.

DrySuits for Scuba Diving

Exploring the world under the sea is always fascinating. But to move freely underwater is not so easy as to move on the land. To be alive under water one has to carry a tank full of oxygen as breathing is not possible under water for human being. Beside that the tremendous pressure and different temperature of the water in deeper are much more different from the land.
For Scuba (Self Contained Underwater Breathing Apparatus) diving the divers, boaters, sailors, swimmers, Water Adventurers, surface-water sports persons often use these things besides the full tank of oxygen:
1. MASK
2. FINS
3. SNORKLE
4. DRY SUIT and so many things.
Maintaining body temperature is one of the biggest problems for the divers. Dry suit is a kind of apparel, which gives the wearer protection from the water to his skin. Dry suits are used to prevent the water entering. Drysuits are used where the temperature of the water is between –20c to 150c.
There are three types of dry suits:
1. Membrane dry suits
2. Neoprene dry suits
3. Hybrid dry suits
1. Membrane drysuits - are mainly built of thin materials of vulcanized rubber or a compound of nylon and butyl rubber. These types of dry suits do not give any real thermal protection in colder water. And these dry suits do not stretch, and needed to be oversized to the joints to give the wearer flexibility at the time of movements. Sailors and boaters who are likely to be out of water prefer these membrane dry suits. Membrane dry suits are easy to wear and put off. Membrane drysuits are mostly used in the spring.
2. Neoprene drysuits - offer the thermal protection in the colder water, keep the buoyancy. Neoprene is thermal insulating material, made of heavy-duty fabric and that fabric is coated with rubber or Polyvinyl chloride better known as venyl. The neoprene dry suits are considered better in comparison to membrane dry suits. Neoprene has some better properties, which make this more useful, chemical-resistant, more stretchable buoyant and waterproof. Neoprene drysuits give greater thermal protection even if there is a leak. Neoprene drysuits are mostly used for water surface sports and in the cold water.
3. Hybrid drysuits - are made by the combination of the membrane material and neoprene material. In hybrid dry suits, the upper part of the suits is made of membrane material and the lower part starting from the waist is made of Neoprene materials. So that the tight fitting lower part of the dry suits gives the comfort to the wearers to kick the water to move a distance when they are swimming. And the loose upper part of the dry suits lets the wearer to free movement of their arms. Hybrid drysuits are mostly used for water surface sports and in the cold water and where the divers are going deeper.
Modern drysuits are having a waterproof zippers & hydro gloves. The zippers are mostly located across the shoulder lines or in the front of the torso, to wear the dry suits easily. Drysuits may have the hydrogloves, permanently attached to the drysuits or with attachment rings. Modern drysuits have the air inflation valve, which empowers the diver to control the buoyancy of the suit by injecting air from the diving regulator to get rid of squeeze under deep water. A drysuit is worn over an insulating undersuit.
A modern drysuit has an air ventilation valve, which allows the diver to release the higher-pressure air from the suit when they are coming out of the water. Ventilator valves may be automatic or manual. It is used as the pressure relief valves. Most of the automatic ventilators are located at the shoulder of the dry suits and the manual ventilators are located at the wrist.
A modern version of the two-piece drysuit is manufactured at Customworks at Idaho. These two-piece drysuits give all sorts of comfort to the divers, boaters, swimmers, sailors, cave divers and the water adventurers. They are making the drysuits considering the needs of its users.

Scuba Diving Masks Tips
June 22, 2008 by admin · Leave a Comment
By Dianne Rein
It's simple to take care of your dive mask with some basic
maintenance tips. And once you are underwater, there's not much
more annoying than a mask that constantly fogs up. Follow these
simple steps for mask care and defogging so your mask will last
you for many more dives.
Scuba Dive Mask Maintenance
Many times, new dive masks have an oily film over the surface.
What works best to remove this? Good 'ol toothpaste! Put a small
drop on the lens and rub it over the areas that have this
residue on them. This would also include the strap. Thoroughly
rinse the mask in fresh water and reinspect to make sure it is
clean. Repeat if necessary.
Just make sure it is not a gel toothpaste. I have always used
plain Crest for this (and to clean my dive slate) with no ill
effects. Removing this film will stop the mask from fogging.
Maintenance of your scuba dive mask is straightforward. No
rocket science here. Here are some simple steps to follow:
Rinse your mask in freshwater after diving. You need to clean
out any sand or grit that may have gotten into the mask and get
rid of any salty residue.
Never dry your mask in direct sunlight. Direct sunlight can
start to degrade the silicone so keep the mask out of the sun.
Thoroughly dry mask before storing. You don't want anything to
start growing on your mask. Not to mention possible odors.
Periodically clean your scuba dive mask. You should clean your
mask with a little bit of toothpaste every now and then. It will
help clean the lens and will also help keep it from fogging (see
below). Rinse well after using the toothpaste and you are good
to go.
Place you mask face-up. Don't put your mask face down when you
are not wearing it. The lens could get scratched - which could
drive you nuts on every dive!
Mask Defogging Tips
There are basically 3 different ways to keep your scuba dive
mask from fogging while you are diving. I have used all 3 while
diving and all 3 are effective. I probably use the mask defogger
solution the most.
Saliva - Yup, good ol' spit. It really does work. I usually dry
and put in on my mask when it is dry. Rinse out after rubbing it
around your mask. Some people get queasy, bacteria, etc. But
we've done it and no harm has come to us! GOOD in a pinch.
Prepared Solution - You can buy a commercial mask defogger
solution at any dive shop for a few dollars. They last a long
time and do work. Just put a couple drops on your lenses and rub
it around. Rinse it out thoroughly, you don't want to get
solution in your eyes. Be prepared to share with lots of other
divers on the boat. There is always someone that ran out,
forgot, etc. You'll be the hero.
Toothpaste - If the above 2 don't work, it may need a more
thorough cleaning with toothpaste as described above (non-gel).
This should solve any problem with fogging that you have.
If you follow these simple scuba mask care and maintenance
tips, you should have a nice clear dive. With proper care, your
scuba diving mask should last for years and many, many dives.
Have fun!

Choosing the Right Scuba Gear
June 18, 2008 by mj · Leave a Comment
Scuba diving is a wonderful experience, but before you attempt it, you have to truly understand the equipment you will be using - because you will trust your life to that equipment and your ability to control it. You have plenty of choices when it comes to scuba diving gear. There are different brands, and the scuba gear you should choose depends on the kind of diving you plan to do, and your level of competence and your skill. The most important consideration, though, is safety.
To scuba dive, you have to wear the wet suit, of course. The sea is of varying temperatures, and you need to be protected at all times. This is what the wet suit does. The material of wet suits is synthetic rubber. Inside, they have a lining of nylon fabric. The wet suit will make sure that your skin remains dry, though he name might suggest otherwise, and makes sure that your body temperature remains within the normal range even in very cold water. It will fit you very closely, right next to your skin.
Now, you have to breathe underwater - for that, you will need an oxygen tank, along with the apparatus that lets you measure how much oxygen you have left in your tank. It will be strapped to your back, and the size of the tank will depend on your dive, and how long you plan to stay under.
The oxygen has to get from the tank to you, of course. This is done through a tube that ends in a mask - a face and eye mask. It is very important to make sure it fits right on your face. To kick through the water strongly, you will need flippers, as well.
Scuba diving can be a wonderful experience, but you do have to put some effort into learning how to do it right with the right equipment before you jump in.

Buying the Right Scuba Gear For Your Diving Experiences
June 18, 2008 by mj · Leave a Comment
Have you always wanted to explore the mysterious world underwater? The ocean can be a place of murky depths, more than just literally! If the idea of exploring those depths appeals to you, you should consider scuba diving. Of course, once you decide that you are in, you have a few practical things to consider before you dive in. One is that you have to make sure that you have all the equipment.
You have plenty of options when it comes to getting the equipment, but the easiest way is to shop for it online. You can find sites that specialize in scuba diving gear. One advantage here is that you can find reviews posted by people who have used it. Unlike in a store out of cyberworld, where you have to trust the store owner's opinion - and who knows what companies he might be promoting - you can do some homework and find out what gear would suit a beginner. There are also plenty of forums where you can get plenty of advice regarding this.
You will need scuba masks, scuba booties, scuba weight belts, a wet suit, swim fins and snorkels, definitely. You might also consider getting an underwater camera - you will come across too many lovely pictures too hold in your mind, and you will soon wish you could make sure that you will never forget a single one. The usual considerations hold true when you buy scuba gear - quality, your budget, and the safety rating it has.
This is why you have to do some research. Having the right gear is very important - your life may very well depend on it. So put in that extra effort and find what is right for you. You can also opt for used scuba equipment. You will find plenty of used equipment that is in great shape and very safe.

Scuba Divers PMS (Practical Maintenance Servicing)
June 18, 2008 by mj · Leave a Comment
There is nothing more important than taking care of something that will take care of you for years to come. If you let your equipment down it will let you down, that's a bare fact. Do not depend on your service tech to keep your equipment in safe working condition when you neglect to keep it clean after each use. That's kinda like expecting your auto mechanic to wash your truck after each time you drive it. Cleaning and maintenance fall on your shoulders (to a certain extent.)
From experience, this is a list I've compiled to serve as a guide and reminder to keep your diving fun, exciting, and most of all safe.
Gear Bag: This is most important in keeping your gear clean and mobile. Having wheels or straps and being durable is a must. Straps come in handy when you are doing a lot of diving from a boat, used as a back pack it leaves your hands free.
TIP; Get a big enough bag to handle all your gear without having to stuff, creating damages. And don't get a bag with any type of logo advertising scuba equipment. That's kinda like leaving your keys in your New Mercedes (Steal Me.)
Mask: Don't throw away the hard case your mask came in, its perfect for transporting and storage. Your mask, and actually all your gear as a rule of thumb needs to be cleaned with fresh water immediately after each use. Certain oils and residues are processed into the materials that your mask is made of, cleaning preserves these, something to do with defog.
TIP; During cleaning it's ok to use toothpaste that does not have any pumice abrasives, this works quit well. There is several products on the market that produce good results for cleaning and defogging, use these if you wish just before a dive and before storing.
Regulator: First stage regulators should be left on a pressurized tank while cleaning. It's very important to prevent water from entering while soaking. During soaking, work buttons, control levers, knobs or any other moving part to remove particles and debris.
Second stage regulators can be removed and soaked in fresh clean water. After drying with a clean towel, store in a plastic bag making sure the hoses are in a relaxed position. Have your regulators serviced at least once a year, or more often according to use.
TIP: Take plenty of bottled drinking water along so you'll have water to spare for cleaning purposes. Take along a big zip lock bag and put your 2nd stage and hose ends in the bag with clean water and sloush them around, empty and rinse a 2nd time, use the rest of the water for drinking and rinseing your hair and eye brows.
Snorkel: After cleaning, inspect purge for good seal, put in mouth, and place your hand over the top and suck. You shouldn't get air in from the purge or around the flex tube.
TIP: Never spray silicone on the valves or snorkel housing, it makes for valves getting sticky and the snorkel housing sticking to the side of your diving hood.
Weight Belts: Before cleaning and storing, remove weights from pockets, this will allow for drying. Store weights in Gym weight bag seperate from belt. This keeps the pockets from getting damaged in storage and transporting.
TIP: Check weight pockets and quick release system for obstruction or damage. If damaged, replace.
BCDs: Just like regulators BCDs should be soaked and rinsed in clean fresh water. If water was allowed to enter the BCD, make sure you rinse the inside of the air bladder.
TIP: Fill the bladder half full of clean water while depressing and holding down on the Oral Inflator button, release and sloush water around and drain completely by depressing the oral inflator button while upside down. Leave upside down and partially inflated during storage.
Wetsuit, Booties, Gloves: After cleaning, apply conditioner too materials found at your local supply store. This help control odors and help from fading and cracking.
TIP: To prevent sticking of zippers, apply a light coat of beeswax by rubbing back and forth. Hang your wetsuit, gloves, booties on some type of hanger that eliminates folding or creasing, and allow to dry before storage. Store in plastic bag.
Lights And Cameras: Water, sand and salt are hard on lights and cameras. Cleaning by soaking in fresh water can add to the performance and lifespan. While soaking, work all moving parts back and forth to release any salt or sand.
TIP: Allow to dry, loosen all connectors, because they will freeze up and disallowing proper usage.
This doesn't cover all your diving equipment, but I think you get the general idea as to what I'm trying to relate. Keeping your gear maintained will give alot more enjoyment to your diving adventure, than getting to the diving site, and everything goes wrong. Makes for a dull day, huh.
If any of your equipment is worn or damaged, do yourself a favor and replace or have repaired by a qualified tech.

Visual Tank Inspections - What Are They Looking At?
June 17, 2008 by mj · Leave a Comment
By Fred Tittle
Visual tank inspections are required in many places every year, in Australia they are required every 6 months, so what are they looking at when they do a visual inspection of your tank?
The first thing they will do after they empty all of the air out of the tank and remove the "head" , tank valve is tip the tank upside down and place their hand under the hole to see what comes out, hopefully just a little bit of water will come out. Most tanks that have been in service for awhile and have been refilled on a regular basis will have a very small amount of water normally less than a teaspoon and some of which will be there from the emptying of the remaining air from the tank to do the service.
Another common find is some aluminum speck's these are formed when the tank is filling they move the little bit of water that gradually accumulates and bangs the water droplets under pressure inside the tank, picture a steel ball bearing in a dryer bouncing around which will cause some small pits over time. When the pits become a certain size the tank needs to be sent for a hydrostatic test.
The next thing they will do is sniff the inside of the tank to see if there are any strange odors this normally points at a problem with the compressor filters rather than the tank.
Most tanks today are aluminum so they don't rust which was a big concern with the steel tanks and the main reason why steel tanks are going the way of the K valve. For certain circumstances they offer enough benefit to override the rust issue (steel tanks can be rated to higher working pressures & are lighter making them attractive for some specialized uses).
The tank vales are made of brass which is a softer metal that aluminum or steel the idea is it is cheaper to replace a valve than the tank. Because there are two different metals you get electrolyses in sea water this will cause the metals to fuse together. If you take the valve off on a regular basis, it is much easier to remove and the likely hood of doing damage to the value, or the tank is greatly reduced.
Another one of the checks is to look at the tank threads if there is damage beyond a certain percentage, the qualified technician will need to send the tank for a hydro, or they will allow it to continue in service based on what see. The qualified technician will measure the damage and note it on the tanks history record and keep an eye on it in future inspections.
They will also feel the water to see if it is oily this is not a good sign as it means that the filters on the compressors were not serviced enough, or the compressor needs to be serviced, which means in many cases that the compressor needs to be rebuilt.
If you own your own tanks in between your visual inspections keep an eye on your filter on your first stage, if it turns rusty or green it is a sign that the tank should be inspected. Also if you get a bad smell you need to have your tank inspected and notify the location where you got your last fills that you noticed a bad smell or taste. If you notice a bad smell or tastes do not go scuba diving with that tank! Remember only let a qualified technician examine your tanks, working with pressurized air and gases can have fatal consequences if done improperly for you, or the unqualified individual!

Do Not Buy a Dive Computer That Does Not Have These Features!
June 16, 2008 by mj · Leave a Comment
By Eli Del
Many people run out and buy dive computers without even understanding the function of a dive computer. Yes, they are cool and will make you look like you know what you are doing. I still think it's risky when people don't do some research first, especially considering that these wonderful pieces of technology are very intricate and expensive. What I'm trying to say is... don't be one of those people who buys one just to look cool and impress others and then finds out that the computer was not the best match for you. Take two minutes to read an article like this and then go buy a dive computer.
There are many brands and many different styles of dive computer available. In order to make this easy and painless, we are gong to spell out the features that you need to look for when you buy a dive computer. If you come across one that does not offer these functions, move on to the next one.
The first thing that you should look for is what information will be displayed on your LCD display. You will need to know what your current depth is, the no-stop time (time left at the current depth before you will need to stop for a decompression stop while ascending) and your total dive time. Other additional features that are considered a bonus are the temperature of the water, rate of ascension and the required decompression safety stop depth and time.
Another function that you will need are alerts, especially if you are in a situation where you might have forgotten information that you learned during your certification training. The alerts are built in to enhance safety and if a high-risk event occurs you will be grateful that a warning buzzer will go off. A high-risk situation while diving could be one of the following: you miss your decompression stop, you have reached the maximum depth at which the dive computer operates, you are nearing the maximum oxygen levels allowed in your body or you are ascending at a faster pace than allowed. In most cases you will not ever come across these events, but if that buzzer goes off you will be glad that you decided to buy a dive computer.
The last feature that you must have in your dive computer is the ability to read the information from your diving cylinder. Your computer should tell you what your current gas pressure is and what the estimated remaining time is based on the rate of gas consumption and available gas.
All of these features above are the most important ones and you should not buy a dive computer if it does not include them. Most dive computers will offer a lot more, but we are not going to go into those here because we want to keep it simple for you. We hope that you have learned the basics of the dive computer and that you are proud of yourself for taking two minutes to read an informative article about the product before you buy it.

Scuba Tank
June 16, 2008 by mj · Leave a Comment
Formally known as the diving cylinder, the scuba tank is a cylindrical metal container used to store a significant amount of high pressure breathing gas for the scuba diver to bring with him or her when diving into the water. The term SCUBA stands for Self Contained Underwater Breathing Apparatus named directly for its purpose.
The term diving cylinder is the technical term for the tank as referred to by engineers, specialists or individuals who speak British English. On the other hand, the terms scuba tank or diving tank are the more commonly used names for those who use American English. Contrary to the common mistake of calling these devices as "oxygen tanks", these tanks are ideally meant to contain breathing gas that is composed of a mixture - not necessarily pure oxygen. As a matter of fact, oxygen is only included in the breathing gas for the tank in special cases.
Furthermore, these diving cylinders are not always used alone, but rather used as in pairs or more in aid in the entire SCUBA diving experience which may vary based on circumstance. For example, divers who go to warm recreational bodies of water usually bring only one scuba tank for the reasons that they don't need too much oxygen support and that it would better allow them to move around if they carry only one tank. This applies to tourists who want to go diving to see corals or tropical fish where they don't really need that much decompression. On the other hand, more professional diving activities like underwater explorations where divers need to go deep into the water or when the water is really cold require divers to bring along with them more than one breathing source.
Scuba tanks aren't also used solely for breathing underwater, especially in the case of decompression diving or more serious diving activities. When bringing more than one cylinder, divers fill their other cylinders with other gas mixtures for other purposes. First, there is the reserve gas tank in case of emergencies. Then there are travel and bottom gases, which are used for the diver to control pressure breathing when ascending or descending into deeper waters and staying on the seabed. There are also other uses for the device, all of which are designed to aid the diver.
Because of this, scuba tanks are very important for every kind of diver there is. If anything, diving would hardly be possible at all.
