How Scuba Diving and Snorkeling Are Basically Done?

Some of the basic requirements for both scuba diving and snorkeling don't differ much, except that scuba diving is for deep water while snorkeling is done on the surface of the water.

It is necessary to know how to swim to be able to scuba dive and snorkel. To do the BSA swimming test is recommended.

The test starts with jumping feet first into water above your head, leveling off, then swimming strongly for 75 yards. You can do breast stroke, trudgen, side stroke or crawl. Turn and for 25 yards do an easy backstroke. 100 yards must be completed in one swim. Stopping is not allowed. If need to rest, you can have yourself float on the surface of the water.

Buddy system is recognized for both scuba diving / snorkeling.

Scuba Diving:

Assess your dive plans, check gears , and review your comprehension of diving signals.

Working in water can be dangerous if you are not fit thus a diver needs to be fit and healthy. Have a physical examination with your doctor before any tiring exercise such as water activities.

Snorkeling:

Snorkeling is not difficult to learn and can be much fun. Snorkeling is often the basic step towards learning to scuba dive and helps build confidence in water.

Basic device for snorkeling includes a mask, fins and a snorkel. You may rent equipment from your local club while learning first how to use them.

When you're about to purchase, always look for quality gears.

When buying a mask, check if it fits correctly and has no leaks. Masks are made of plastic, rubber or silicone which is more expensive. Silicone mask is more comfortable and durable.

Mask lenses should be of tempered or toughened glass for eye protection and scratch resistant view of the underwater world. It is recommended to seek for professional advice at your sports shop in choosing the best mask. Buy the best you can afford.

To be able to breathe at the surface of the water without lifting your head for breath, you will need a snorkel. Basically, it is a tube with a mouthpiece. Different mouthpieces are to be tested to be able to pick for a comfortable fit. Ask an advice from your snorkeling club instructor regarding mask/ snorkel care and maintenance.

Fins can either be a shoe fin or an open heel fin. Take note, test different products for comfort and size.

In warm countries sun skin protection is essential while snorkeling. Use water resistant sunscreen and wear a t-shirt that is UV treated.

If you're in a cooler country, a wet suit will provide warmth and protect against abrasions and stings from sea creatures. This would apply to both scuba diving / snorkeling.

Scuba diving and snorkeling can be incredible fun. Such a wonderful experience of fascinating marine sights to share with friends and family. However, most importantly, for diving safety, never forget the basic measures to be observed which includes the rule of never diving alone.

Proper Use Of Scuba Diving Marine Equipment

Scuba diving is practised for many reasons such as recreation, but it also forms a part of many jobs within the oil and gas exploration sectors. The entire purpose of scuba diving gear is to sustain the diver while he is underwater for a prolonged period of time. Such marine equipment typically involves a canister of compressed atmospheric air (such as Nitrox) and a regulator through which the diver can breathe. The latter serves to convert the ambient tank pressure into atmospheric pressure, thus allowing the individual to reach depths that would otherwise be impossible. Buoyancy compensators can be used when one needs to dive below the accepted recreational standards. Since humans are incapable of breathing underwater, it is essential that scuba diving equipment be used properly in order to avoid potentially deadly occurrences.

Maintain All Marine Equipment:

It's not safe to assume that all equipment needed for a dive is in proper working order without doing a thorough check first. Even if you acquire your gear through a marine equipment rental company, you will need to perform the proper checks yourself.  Of primary importance is any device associated with the free flow of air. This includes the rebreather, diving regulator and pillar valve on the cylinder tank. Pressure gauges and dive computers should be tested to ensure that their readings are accurate. Any storage instructions should be strictly followed, for example wetsuits are to be kept out of direct sunlight or they will start to degrade.

]]>

Pay Attention to Marine Equipment Meters:

Marine equipment, such as dive computers, was designed with safety in mind. They serve to furnish the individual with information on the depth attained, the time spent underwater and the remaining air supply. This allows for surfacing without running the risk of decompression, but only if any warnings are heeded. Ascending from a dive is a slow process and one should make allowances for the time needed to do so. Complacency is very risky.

Emergency Marine Equipment Is A Must:

Any experienced scuba diver knows that while there is much joy to be gained from it as a form of recreation, it is also a dangerous pastime. This is especially so for those whose jobs include underwater welding as they are often forced to work at depths that are not suitable for the occasional scuba diver. As such, taking along emergency marine equipment is a necessity rather than a choice. For those going to greater depths, a second cylinder tank, pony bottle and extra air source could be considered as vital supplies. Scuba divers who frequent caves, or dive at night, should arm themselves with at least three light sources.

It is the diver's responsibility to ensure that all marine equipment is in working order before attempting a dive. Not doing so can result in serious consequences. Not only are regular maintenance checks necessary but one must also exercise care when purchasing marine equipment in the first place. While cost is a factor, it is more important that the marine equipment dealer should be reputable and hold themselves to the highest standards of safety. If one is seeking scuba diving gear for recreational purposes, look for a company which is affiliated with industries as they tend to be more stringent.

Question by pizzapie: How do I get the bottom timer back on Hollis DG02 dive computer?
I recently got a Hollis DG02 wrist dive computer, and when I first got it, it would count/show the elapsed bottom time on the display. However, I must have hit something to put it into another display mode. How do I get it to display the bottom timer again when I dive? Thank you in advance, scuba friends.

Best answer:

Answer by moviebuff
When you were first certified your instructor should have told you that an important part of using a dive computer is to read and understand the manual.

Here is a link to the manual for the DG02: http://hollisgear.com/pdf/manual_DG02_12-4023-r01.pdf

That should tell you everything you need to know about settings & modes and how to change them.

My trip to la jolla with scuba diving equipments

Diving in La Jolla, California a few years ago became quite a treat. I had been asked by a friend of mine who always liked to challenge himself and others. See, I like hot tropical weather. La Jolla is not hot tropical weather. This was not going to be a day of snorkel equipment. My new scuba accessories would come in handy.

67, 68 degrees at best that day, the water wasn’t very tropical at all. That was back in the days when I thought diving at 67 degrees was cold and unfit for diving. I guess I’ve changed my mind since then. I kind of had to change my mind.

Steven had been my friend for years. We go back to the days when we took our diving lessons at the YMCA. It was just something we always shared. We loved diving. We’ve been diving since, but our lives have taken us in different directions and we live in two different parts of the world. Him in California. Me in the Southern most tip of Florida.

]]>

When he got a hold of me to dive with him in La Jolla, I couldn’t turn him down. Steve didn’t really answer me when I asked him how cold the weather was. He just sort of shrugged off my question, "It's warming up quite a bit."

My SCUBA accessories included my new CompuMask from Aeris, which got Steven going. "Does that thing have a GPS and play songs for you while you’re down there?" His laugh was a full bellow that echoed over the water.

"No, but it will tell me the temperature when I get down there." That shut him up real quick. It won’t. But, what does he know?

The Aeris CompuMask HUD Dive Computer Mask can tell you just about everything else. It has an LCD panel that does not hinder your dive whatsoever, but presents critical information to you that you need. Like, your depth, your elapsed dive time, your cylinder pressure and your remaining dive time. It has a USB cable and connection as well as software so that you can create the settings on your computer and then upload them to your mask.

I got a little cold. But, I stayed tough. I hadn’t been in cold water in a long time. I tell you what though, I knew when to go to the surface. Steven was serious when we got back on land. "How did that thing work for you?"

"It worked great! I got to see everything and stay on top of the dive."

"Really, I might have to get me one of those things."

The guy who likes to rough it. It's a wonder to see. Steven is finally going to step up into the new generation of diving.

Scuba Equipment Essentials For Specific Diving Conditions

People that just start out scuba diving are intrigued by the idea of going under the water and seeing many amazing things, however they are not aware of how much you need to know about the equipment that must be utilized. Most beginners learn early on that specialized gear for different types of dives is necessary and must be mastered.

This information is limited, however, to recreational diving as this will apply to most people that begin to learn this sport. People that do not have their own equipment typically will lease what they need while on vacation or holiday.

Of course, it is okay to do this, but before you do, it is important that you understand a little bit about the equipment that you're using. It is actually very dangerous to use diving gear that you have never used before or are not familiar with. As you probably have guessed, the more familiar you are with various types of scuba equipment, the safer you will be when using it.

Many divers use various units of equipment, one of which includes a demand regulator which we will discuss here. First of all, there are one or more cylinders that are filled with air that you wear while scuba diving.

]]>

A diving regulator is used with the cylinders receiving the air within them which is stored around 3000 to 4000 PSI. The purpose of the demand regulator is to provide air to the diver at an appropriate pressure level so that they can breathe. Other factors such as the depth or level that the diver is at modify the end result.

Multiple hoses are not used on open circuit configurations instead of one hose. A two-stage regulator design is often used with a single hose regulator so that high-pressure cylinder gas can be taken care of. The demand valve found in the mouthpiece is actually the second stage regulator.

With just a few small adjustments, each person can figure the demand valve to supply the proper amount of air to the diver. High and low pressure devices work together to provide the right levels of air for each of the divers. Whether you are looking at breathing normally through your mouth, or three or diaphragm, each device provides a solution to make life easier.

Well known throughout the scuba diving community is what is called a dive computer. A very important instrument, this actually prevent you from getting the bends or what is commonly called decompression sickness, by allowing you to monitor your speed as you rise toward the surface. The calculations that it performs will give you a safe ascent profile, basically a guideline for rising to the top at a speed that will prevent you from getting sick.

The software actually computes your speed as you ascend, and also warns you as to when you need to do decompression stops along the way. Calculations are even biologically derived by utilizing inert gases in your body to further refine the information you need to reach the surface safely and without harm.

This device has many different mathematical parameters that it uses to calculate a variety of useful results to make your diving experience safe and fun.

Diving is definitely a fun filled event, some of which involves extensive scuba training with equipment. Dry suit diving, and cave diving, have become very popular over the last few decades requiring more special gear to be manufactured.

The military, and the industrial complex have long been interested in these types of scenarios. SCUBA diving will provide you with exciting experiences that will last a lifetime, and you will be able to learn constantly.

Diving Wrist-watch, How to Choose?

Talking constructional discuss about the features of a good diving watch, there are numerous choices of diving watches but not all of them meet the minimum requirements of advanced scuba divers. The question is, we should pay attention at what details while carefully choosing diving wrist-watch?

Despite the fact of none of scuba divers nowaday diving without quartz-crystal computer device. Bringing real diving wrist-watch as a secondary control system will not only instill confidence but it will become a lifesaving gear in case of the primary one is malfunctioned.

So which criteria is needed to be taken into consideration regarding to choose real, functional and reliable diving chronometer? What functions they must have to serve all the needs of diving duties?

Criterias:

The first important factor, comparing to diving computers, they must to be mechanical devices. Today most manufacturers understand clearly that hermetically and firmly sealed body is a must for diving watches. The body must be made of massive high quality steel or pure titanium or should not be multi-pieces. TAG Heuer watches are a good example because of their one body covering.

]]>

Generally, diving watches have circular section thickening ring between their body and cover snap together with screwings.It should have considered side protection to protect from hammering and shock resistances. For such reasons, some manufacturers have moved clock winder from vulnerable place behind digit "3". For example, this construction feature is found on Citizen, Ikepod and Sinn watches. Another useful material is watches made from crystals of antireflective sapphire which can’t be scratch by coral reeves of hulls of sunk ships.

Wrist-watches that have all these features can easily provide water-resistant up to 10 atmospheres i.e. 330 feet. Most professional scuba diving watches can sustain much harder water pressures. With some models of TAG Heuer and Sector watches you can dive up to 3280 feet deep (if you dare)! Sunlight cannot reach such depth, so your diving watches need to have big and bright self-glowing digits so you can easily see the time even in very low light situation. Display should have markers placed with 5-minutes range and must be clearly seen from less than a foot underwater. Same requirements belong to hands and markers.

Diving in ocean depths we need to know not just the daytime but especially how much relative time passed from the start. For this reason, advanced diving wrist-watches should have rotating bezel with engraved dive time markers to limit diving time and safty stops. We advise you to look for a watch model where bezel is rotating only counter-clockwise not unidirectional in case of mistaken rotating, the diving time will only be less, not more, and avoiding possibility of dive overtiming and causing decompression sicknesses.

While purchasing a new or second hand diving watches, they should be tested to be qualified of these standards:
- Dial Readability
- Antimagnetic Behaviour
- Shock Resistance
- Bezel Rotating only counter-clockwise
- Reliability of bracelet, clasp and rim.

The watches should also to be unaffected by salt water and temperature swing difference. With all these conditions the watches must work excellent. Yes, it makes them harder to manufacture but while comparing to human life, it is very worthwhile!

How Important is Using Proper Scuba Diving Equipment?

Discovering the depths of the ocean has always been an enchantment to mankind. Below the waters lies a world as rich and diverse as our own above the surface. For humans, exploring the waters filled with beautiful and mysterious creatures in fascinating locations proves difficult and treacherous and requires scuba diving equipment.

Underwater is not our natural habitat. To help sustain in shallow waters, divers use basic equipment like snorkels but deeper diving becomes problematic. The rising pressure from deeper sea levels also proves dangerous for deep sea divers.

During 19th century, great developments has been made in the area of diving and equipment through scientific research. Technology like carbon dioxide scrubbers and compressed air pumps were developed making it possible for divers to stay under water for longer periods of time. Safe limits for compressed air diving and the effects of water pressure on the body were established.

]]>

Through this studies and technology that scuba diving and scuba diving equipment eventually developed. The term "scuba" started as an acronym, Self-Contained Underwater Breathing Apparatus, during World War II when it was developed for underwater warfare.

The scuba set which is an independent breathing set supplying the diver with compressed breathable gas is the most important piece of scuba equipment . It is vital for breathing underwater during scuba diving.

Modern scuba sets can either be open-circuit sets or closed-circuit sets.

Open-circuit sets allow the diver to breathe in from the set and clear the exhaled gas into the surrounding water. The closed-circuit set, also known as a re-breather allows the diver to breathe in and to exhale into the set again where the air is being reprocessed.

Preventive measures are need to be taken for possible diving health risks and other hazards. Having the right scuba diving equipment will go a long way towards ensuring enjoyable and safe dive.

A breathing set is considered a fundamental piece of equipment for scuba diving. In some circumstances, it is recommended that a snorkel be used instead. Breathing set goes with a diving mask to protect eyes when submerged in water. Swimming fins for your feet help you for easier underwater mobility and to surface quickly when needed.

To keep your body warm and regulate body temperature, you will need a diving suit which is especially important in cold water. When body loses too much heat and temperature is unusually low, hypothermia sets in . A hood is as important as covering the rest of your body. Suits protect against cuts under water and possible stings from sea creatures.

To utilize appropriate scuba diving equipment will surely aid in providing safe and enjoyable dive.

Learning Scuba diving - Certification and what do you learn whilst training for it

So, how do you obtain the scuba diving certification? The only way to receive this certification is by signing up with a scuba diving school which basis its curriculum with a recognized scuba training agency. Such scuba certification agencies regulate and represent diving professionals and operators whilst also promoting the sport and the marine environment.

On successful completing the training, you will be certified as a scuba diver. You will then receive a scuba diving license which will allow you to scuba dive with diver operators and rent scuba equipment.

Because there are many different scuba diving certification agencies around, it is worth to find out which ones are closer to your home. It is important to understand that the approach to scuba diving will vary for each agency. However most popular agencies will offer very similar training for recreational scuba and will recognize each others qualifications.

Some Agencies are global organizations such as PADI and NAUI and thus recognized worldwide whilst other agencies are closely related to their country of origin.

In the theory part, you will be learning scuba diving safety techniques and basic scuba concepts. You will likely watch videos introducing you to scuba and will be briefed on scuba safety practices. Within the theory lessons you will also get to learn the different scuba hand signals for use underwater communication.

]]>

Most important of all, you will be introduced to the different diving equipment that you are soon going to use. During this time you will also be reading text books and gaining an understanding of the relationship between depth and pressure. Knowledge of how to use the dive tables to plan a dive and assembling and maintaining your scuba equipment will also be provided within this part of your scuba diving lessons.

The next part of your scuba lessons is the confined water training. Finally within this part of the scuba course, you will actually get your first experience to breathing underwater. These sessions will train you on how to use your equipment and practice your buoyancy and surfacing skills. There are many skills to practice and learn, so you will probably have several sessions to practice them out.

At the end of the theory and confined sessions, you will be required to pass a final exam to progress to the open water portion of the program.

The final portion is the open water training. Here you will get to test the skills learned from the previous confined water training sessions. You will here practice the scuba diving skills with your instructor until you are completely confident and can perform them with ease in a real diving situation.

During these scuba dives, you will be given an orientation to some of the local conditions and environment you will be diving in once you have completed the course. The good thing about it is that you will also get to check out the underwater scenery. Be ready to become addicted to diving. These skill evaluation tests are spread over approximately four different dives. Once your instructor is satisfied with your progress and have passed all the necessary tests, you will be certified as an official scuba diver.

Purchasing your own Scuba Diving equipment

If you are interested in taking up Scuba diving as a hobby, it is important to invest in your own equipment. Scuba diving can be a risky activity and having your own equipment can reduce the risk of equipment malfunctioning since you will be aware of the quality and condition of your own Scuba Diving gear.

For those of you who are looking to purchase your own Scuba Diving Equipment here are some of the most important pieces of equipment that you can buy.

Since the BCD is a very important piece of Scuba Diving equipment it is important that you have the right fit as well as one which is of the highest quality. The BCD is what you use to control your buoyancy and therefore any malfunction could be extremely risky. If you own a BCD then you are not only guaranteed that it will fit you well but you will also be able to make sure that it is in working order.

]]>

Having your own regulator and alternate is quite beneficial since this is what you will be using to get your air supply. Having your own instead of one that you have rented means that only you will have used it and you do not have to worry about the countless others who might have used the same regulator.

These two are probably the least expensive of the equipment that you will need to take up Scuba Diving. Having your own fins and mask means that you are ensured that they fit you correctly as well as that they are in good condition. Having your own pair on fin and mask is also beneficial if you enjoy snorkelling. Having your own fins and mask means that you can partake in both Scuba Diving and snorkelling.

This is a considerable investment but it is a piece of Scuba Diving Equipment that is very necessary for a diver to be both safe and independent. A dive computer is an essential tool that tells you key information that allows you to dive safely and therefore having your own is quite important. Purchasing your own dive computer will allow you to select one of the highest quality and highest functioning. You will be able to get used all the functions and get familiar with it with each dive.

Whether you decide to buy all the equipment you need for diving or just a selected few pieces it is important that you choose gear which is produced by a reputed manufacturer and is made maintaining the highest quality.
