How to choose scuba diving equipment – selecting a scuba mask

Article by David Leigh









When selecting a scuba mask it is essential that it fits your face well to ensure that it is both comfortable and leak free. Without a good seal against the face you may spend much of your time clearing the mask of water, while an uncomfortable mask detracts from your diving experience – both lead to enjoying your dives less but because they distract you from your environment they are also potentially unsafe.

Finding a mask that fits your face well is a simple matter and can be tested with the following three-step procedure:

1. Place the mask on your face but with the strap placed out of the way.2. Inhale slightly through the nose so that the slight vacuum holds the mask on your face. 3. Test the fit by gently moving your head and it should remain in place if you gently try and pull it away from your face.

At the end of this test you will have determined whether a scuba mask fits your face well or not, so now it is time to examine other features.

Style

Most masks on the market today have low internal volume, which means that the mask is more comfortable to use since the diver won’t experience much mask squeeze during the dive. This style of mask is now usual and features a pocket for the nose that protrudes forward of the lenses and as well as low volume the large lenses allow for a wider field of view, but models to look for include Cressi Big-Eyes, although it is not suitable for all face shapes.

Colour

This is purely a matter of personal preference and you may not have any preference at all. The traditional colour for masks, and all dive equipment in fact, was black due to the use of neoprene. These days silicone is used instead for masks, which is more flexible and less susceptible to sun damage. Silicone can be supplied transparent or in a multitude of shades due to the use of colouring agents, but many people still choose black. However, some people claim masks made with transparent silicone give better visibility due to the greater amount of light allowed to enter.

Skirt

High quality scuba masks feature a silicone skirt that thins towards the edge, allowing for a better and more comfortable fit against the skin of the face. Often you’ll see a second skirt inside the upper edge of the skirt that allows a better seal. Its absence at the bottom is to allow water to drain more easily from inside the mask.

Strap

There are many occasions when you’ll need to adjust your mask strap and so ensure that you find the mask easy to adjust. If you wear gloves when diving then make sure you can adjust it quickly and easily with gloves on. And while on the subject of mask straps, remember to always carry a spare – it is one of the more common equipment failures and the lack of a spare may mean you have to remain on the boat when everyone else is enjoying the submarine world.

Those are the most important factors to consider both when buying a new scuba mask or using rental equipment from a dive centre. By ensuring a good fit you ensure your own comfort and safety while a combination of the other factors will mean you get many happy years of service from your scuba mask.

Do you know that scuba diving has a great healing to mind, body and soul?

Do you know that scuba diving has a great healing to mind, body and soul?

Article by Felice









Water always have a therapeutic effect on human. Come to think of it, 70 percent of the earth is water, 70 percent of your body is fluid. Water is such an important element in our life, second in rank to air in terms of life giving.

Water music always has a soothing effect on the mind and soul. That is why, you find a lot new age music features water as the background for the music. In Feng Shui element, it is good to have a fountain, a waterfall in the house or compound provided it is positioned in the right sector of course.

Now aquariums are a hit with homes and you have aquariums in homes, hotels, restaurants, clinics and even hospitals. In some clinical experiments done in mental hospitals, the use of aquariums have a calming effect on the patients, and it also has an effects on autistic children. Interesting studies but still experimenting stage. More studies should be done in these areas involving water element.

The closest thing I have been is to go to an underwater marine park. How do you feel when you are in the tunnel with the sharks, rays and fishes swimming above you? Great isn’t it and you don’t feel like going out of this world. You feel so relax, so peaceful and free from worry and stress.

This is the very reason, why I am introducing you to the marine life in the seas of Sulu and Celebes. Just at the Eastern side of Sabah, on the northern corner of the third largest island in the world, Borneo, you have great diving sites to see all the rich macro life and great pelagic fishes of the world. Where there are rich macro life, there are also big fishes and you have the best of both world, great beaches to sunbathe in and great waters to explore.

Now, don’t take my words for it but then, I won’t be writing this if it not true either. The late great oceanographer, Jacques Consteau has dived Sipadan and so have so many others famous divers. They can’t be all wrong and a lot of these dive sites are now ranked in the top ten positions in the world and a must see on the wish list of every avid divers.

The underwater world is a completely different landscape. In crystal clear water dive sites such as the one at Sipadan and the surrounding sites, you can see alot of macro life that you do not see on land.

The fans, corals and rocks formation are completely different from the landscape. The colors are a kaleidoscope of a huge range of combination of more than the rainbow colors. You have heard of color therapy and I can understand why divers often came up very relax and calm.

Also, it seems that divers tend to have better observations and this is a good habit to cultivate on land. Divers told me that one has to be extra observant for two reasons. One, if you don’t want to miss the details, especially the macro world, you have to keep your eyes open wide but not shut (like in Tom Cruise’s movie) and be on the alert to observe any movement.

Some of the fishes like crocodilefish, stonefish are master of disguise and if you are not careful, you will missed them. For reason number two, in the underwater world, you must be really observant not to mistake the fish for a stone or coral. Should you accidently step on one or touch on one, you are going to have agony pain and worst, the toxins can be fatal if treatment is not on hand. But the benefits and learning out-weights the dangers and if you are careful diver, it is fun and healthy for your mind and body.

Diving is great for motor co-ordination of the limbs and body. And because water has bouncy, the weight of the body is supported by the water and you feel much less weight in water. This gives you a lot of agility in the water than on land and we find that divers tend to have great fitness. Breathing is great for divers and they have to learn to breathe correctly with the oxygen tank. All in all, scuba diving is great exercise for the body, great for the mind and soul and great for knowledge.

Top Five Gift Ideas For A Friend Who Loves Scuba Diving

Article by Simply Scuba









Scuba diving has become increasingly popular over the last decade, with thousands of people now listing it as one of their favourite hobbies. But what can you buy someone who loves to scuba dive? Well, you need look no further for the answer.

The Mares X-Vision Liquid Skin is a perfect underwater face mask, for both recreational and professional drivers alike. It promises to mould to the skin, taking it to a new level of comfort. Lightweight, with a soft silicone portion that rests on the face, this mask is designed to fit any size or shape of face and is suitable for all kinds of diving, from snorkelling to free driving and costs ?40.95.

Or at the cheaper end of the market, but equally important for any serious diver and the perfect accompaniment to the Mares X-Vision Liquid Skin, is the Simply Scuba Mask Strap Wrapper, which retails at just £5.00. Ideal for the diver with either longer, or less hair, the strap wrapper is designed to fit over the existing mask strap to ensure that putting on and taking off the mask is much more comfortable. Once again, this product is suitable for all divers who don’t want to damage their hair (or head) when using the mask.

A Scubapro Octopus Holder is known as one of the best available – and it won’t break the bank at £5.95. The diver uses this to hold their alternate air source ready and can be easily released by an out of air diver with a quick pull. It also has the added benefit that whilst in the ready position, the internal plug stops the Octopus being filled with dirt.

Scuba diving is something which needs to be taught and not everyone can do it. But for those who have what it takes, it is imperative that they are able to communicate with others in the water. At £14.00 the Submerge Shaker ensures your loved one’s safety. A hand operated scuba-rattle it has been extremely well constructed and is known for its volume under the water at any depth.

An absolutely perfect gift, – which may not mean that much to the non-diver, but would impress someone who does, is the Mares Trilastic 5mm Boots that you can buy for under £30. These boots have been designed specifically to give the wearer the most control and power when swimming and are also perfect for cold water dives or anywhere the diver may have to navigate rocks. The area around the ankle is made of super-elastic material, with the lower section made from neoprene, which ensures warmth and endurance.

All this comfort and safety for a cool £29.90!

Exploring the Temperate Seas by Scuba Diving

Posted by Extreme Motion on Jul.31, 2011, under Uncategorized No Comments

Exploring the Temperate Seas by Scuba Diving

The richest of all marine ecosystems, temperate waters are the stretches of ocean between the poles and the tropics. These waters are hugely changeable, offering a seasonal range of conditions at any one dive site, often accompanied by a variety of visiting migratory species.

The Temperate Zone

It is difficult to define the temperate zone precisely; because major ocean currents can artificially extend temperate waters into tropical regions, or push temperate species into near-polar regions. The best definition is perhaps found in the temperature range of the water: true temperate waters rarely sink below about 39°F (10°C) or rise above 68°F (20°C).

The positioning of the temperate zone means that its waters see a greater change of conditions from season to season than tropical and subtropical seas. In particular, the amount of light hitting the surface of temperate waters varies considerably between winter and summer, and this leads to a seasonal variation in productivity—the sheer amount of life that an ecosystem can support. At the base of the food chain in the marine ecosystem are tiny organisms called plankton, which are dependent on light and nutrients for growth and reproduction. In the winter, when even water near the surface receives little light, conditions are poor for plankton growth, and so productivity is low. However, during the stormy winter months there is considerable mixing of cold, nutrient-rich deep water with the surface layer, and so in spring, when the amount of light hitting the surface of the water vastly increases, conditions are perfect for the growth of plankton. Huge spring blooms develop, attracting plankton-feeding species and their predators, and the waters become rich in marine life. Productivity drops again in summer, because, even though light conditions are perfect for plankton growth, there is little mixing between the surface layer and deeper water, and so nutrients become scarce.

Temperate Diving

Diving in temperate waters is not the crystal-clear, warm-water experience beloved of the coral reef diver, and requires more equipment than diving in tropical regions. However, some of the localized ecosystems within temperate seas, such as the majestic kelp forests found in certain coastal regions, are extremely dramatic. When dived at optimum times in the season, temperate waters are rich in life. The seasonal blooms of plankton draw a range of migratory species, and also attract impressive predatory species, such as shark and tuna.

Plankton Blooms

Plankton are free-floating animals (zooplankton) and plants (phytoplankton) at the base of the marine food chain. When environmental conditions are optimal for their reproduction, they can multiply very rapidly, creating huge “blooms” of many millions of individual plankton. Where massive blooms of phytoplankton develop, the sea can literally turn green.

Scuba Diving in South East Spain, the Province of Murcia

Scuba Diving in South East Spain, the Province of Murcia

500 Madridian Scuba divers per week can not be wrong.. can they? I’ve been living here in Mazarron now for almost 3 years, it was the sun that brought me here, far away from the English rains and cold Monday mornings. Being a diver i wanted to be near the Mediterranean coast, i never took much notice of the town that i was to end up living in, i sort of just checked out if there was any diving around here.. luckily for me there was.

Within a few weeks of being here i took myself down to the local dive centre and booked myself a dive right away, i was not expecting much as i have Scuba’d in some very exotic locations worldwide and been a little spoilt i guess. Two minutes boat ride from the Puerto the boat was tied off to the bouy and us divers aboard were briefed by the DM as we kitted up, the dive site was called El Bajo De Emilio. The DM’s brief was pretty good (well it sounded to good to be true) a small undersea mountain with 20 wrecks around it and a statue?, Barracuda, Grouper and Eagle Rays, he sure made it sound good.

Ten minutes later we were in the sea and dropping down the line to a spot on the side of the mountain in 15 metres of water, I couldnt have asked for more the visibility was around 30 metres and straight away even when descending i could make out the eerie shape of 2 wrecks in the distance and then a school of Tuna not 10 metres away, it was looking good, a very promising start. It just got better and better, we covered around 5 or 6 wrecks all around 30 metres long, saw the statue “La Gorda” standing upright on  her plinth which was settled on the sand. There were Barracuda, Pez Luna (sunfish), Grouper, gigantic Toothed Bream, Congers and lots of Moray Eels..(no Eagle Ray though). Fifty minutes later we were back at the line doing the 5metre stop it was a perfect dive except for the noshow from an Eagle ray, But hey “whats that in the distance heading this way”?, the Eagle Ray winging his way along, the dive had now gone far beyond being perfect.

That was it for me i just had to take my PADI instructors exam and dive here permanently, so i did, here we have 13 quality dive sites all within 15 minutes boat ride from the Puerto, if you want more info about the diving here in Mazarron then feel free to hit me up (details in my profile) and i will gladly answer any questions that you have and also offer advice on diving conditions etc.

Footnote.. Every friday for 6 months during spring and summer approximatly 500 Scuba divers from Madrid (6 hours drive away) descend on Puerto De Mazarron to do just 2 or 3 dives and then drive all the way home. So can they be wrong?. No way, but they do know how to keep a secret though, the diving here is outstanding yet little is ever mentioned, Do others know it exists?

Hi there, i am a PADI professional Scuba Instructor and based in South Eastern Spain, in the province of Murcia. The town i live in is called Mazarron its a coastal town and very “Spanish” the diving here in our bit of Spain is probably the best that Spain has to offer. Diving in Mazarron

Best Scuba Diving Vacations

Take for example, my experience learning wind surfing. I learnt the sport when I was If I were to learn this sport now at age 42, chances are I would not go far and would probably give up after 1 or 2 tries. Learning wind surfing was like battling with all the forces at the same time! We’re talking about trying to balance on choppy waves on a slippery wet board, at the same time maneuvering a sail which weighs a lot more than you in the correct direction that you want to go.In the process, I contributed blood and flesh from cuts on barnacles and bruises from hitting the surf board a lot more than once before falling into the waters.

To get going with, scuba diving tuition and an authorized scuba diving certification is necessary in advance of exploring the underwater environment. Anticipate to pay around 0-0 for the study course main as much as the scuba diving certification.

Like different professionals, scuba diving instructors also used to become students. They instigated with much easier guides on scuba diving after which slowly moved on to higher courses. Of course, via the process, they have been capable of see much more to scuba diving than simply possessing entertainment whereas diving. They have been capable of see a special side of scuba diving that encourages their situation to talk about the game to others.

How to Pack for a Scuba Diving Vacation

Posted by Extreme Motion on Jul.29, 2011, under Uncategorized No Comments

How to Pack for a Scuba Diving Vacation

One area of scuba diving education that seems to get little attention is how to pack your gear. My very first scuba diving vacation was when my wife and I got married in Hawaii and did our honeymoon in Tahiti. I toted a full sized, scuba suitcase from Chicago to Maui to Honolulu to Papeete to Bora Bora to Moorea, then back to Honolulu and finally Chicago. Each leg of the journey, I had to pay extra for the weight (and extra bag) of scuba gear. I carried way too much unneeded stuff. In today’s economy, the airlines are looking for any reason to bend you over and nail you in the keester with luggage fees. So planning how you pack, can save you some money in the future.<!–more–>

The Thinking Dive Traveler

Before you start putting anything in a bag, you first have to go over everything and look for items that can be removed. I’m currently packing for a trip to Turks and Caicos. As I was folding up my mesh bag for carrying gear on a boat, I noticed that I still had a bunch of teaching slates in one of the pockets. I removed the backup light from my harness as well as the backup double ender I keep and stainless steel buckle used to hold my canister light in place. Even though I could really use my stainless steel backplate, I’m taking my aluminum plate to reduce the weight of the bag (I’ll add a weight belt when I get there). By making these small changes, I was able to shave off 8 pounds from the bag. That may not seem like much, but it will help me get below the “heavy” bag weight limit the airlines impose. Remember, every ounce counts. So get into the mindset to eliminate even the smallest item if it isn’t needed. If your bag is even 1 pound over the weight limit, you can bet a paycheck the airline will charge you extra. There’s a war raging for your dollar. You need to fight to keep it. Make sure you know the weight limits for the airline you are traveling with prior to packing up your dive gear.

The Rental Option

Even if you own your own gear, you can still opt to rent gear from the dive operator you are diving with. This way you won’t have to worry about packing, and maybe losing your dive gear. I’m always skeptical about renting gear in other countries. Who knows how well it has been taken care of. I get the willies just thinking about donning a wet suit that a thousand people may have puked on, peed in or done something worse. So I prefer to take my own gear. Certainly renting gear at your destination is a viable option. Just do your homework into how they service their gear.

Maximizing Bag Space

Looking at how you pack your gear can be a big benefit to you. You are only given a finite space to place your gear in a bag. My shorty wetsuit and mesh gear bag will lay perfectly flat on the bottom of my travel case (when it’s laying down). I then put my backplate and wing on top of that. Make sure all of the air is out of your BCD prior to packing. My regulator bag sits nicely inside the harness next to the backplate. I have fin “pockets” on the inside of my travel case. Even my Jet fins will fit in them. My wet suit boots go in the foot pocket of my fins. The lid of my travel case has a padded zipper pocket on the inside of it. My mask fits in there nicely. I carry my bottom timer/depth gauge on my carry-on bag. By packing this way, I have plenty of room for souvenirs to bring home. Just as long as they don’t push me over the bag weight limit. In the past, I made mistakes by packing things I thought I needed. For example, I own two regulator bags. One is a very nice, thickly padded XS Scuba one. I love that reg bag. But it is too bulky to travel with. So I have a less bulky one, that isn’t as nice, to carry my regulators in. I’ve also stopped carrying multiple Pelican cases. In the past, I took as many as three Pelican cases to hold “stuff”. I’m now down to only one small case, to hold my wallet and sunglasses when I’m in the water.

Make Sound Travel Decisions

If you take frequent scuba vacations, make sure that you think through your gear choices when traveling. It doesn’t hurt to have a travel BCD that is smaller and lighter than your home BCD. Same thing with fins. As much as I love my Scubapro Jet fins, my old Dacor Panthers save me 4 extra pounds and I can move through warm water just as efficiently as my Jets. I also have warm water boots that are low cut and a thin rubber sole. Whereas my home wet suit boots are high tops with a thick, hard sole.

Otherwise, if you don’t mind paying the extra fees for exceeding your checked bag weight limit, then feel free to keep stimulating the economy. We could use all the help we can get.

Dive Safe,
Duane
Precision Diving

 

When I am not teaching, I can be found diving year round, in a wide variety of environments that include the Great Lakes, to the warm clear waters of the Caribbean and South Pacific.

I have a passion for diving and strive to be the best possible diver I can be. This passion provides the motivation for me to accomplish between 100 and 150 non-teaching dives per year. This gives me the experience to increase my knowledge pool to share with my students. I believe in continual practice. A great diver makes for a great instructor.

Can Choice of Scuba Diving Gear Really Make a Difference?

Can Choice of Scuba Diving Gear Really Make a Difference?

Article by Mark Jenner









Make a mistake with choosing your diving gear and you may well give up the sport altogether. Comfortable diving makes for a happy and safe pursuit of this sport. This is why some thought and a lot of research should go into the acquisition of your diving equipment – given that a full set can cost several thousands of dollars.

When starting buy yourself a comfortable mask that you know you can rely upon, and a set of fins also. These close fitting items are key to your comfort. The mask in particular must be leak free and a good fit on your face – loaning a mask will lead to leaky spoiled dives. When learning in colder water you should get your own pair of warm gloves at least, and if possible your own suit. You can buy the other items of scuba gear later on.

You can qualify using equipment supplied by your instructors quite easily, getting to know the different options as you go along. When it is time to buy your own tanks and aqualung you will know what you want and what you will feel comfortable with.

For example, most people in a cold water diving club will be recommended to buy a 15 litre diving cylinder for the type of diving they expect to be doing. However, there are many divers who will find this cylinder heavy, and because their breathing is slow and regular might find that they only need a ten litre cylinder which is far more comfortable to carry.

The advice is just as important for more advanced divers moving on in their diving careers. For example, take the diver who is commencing technical diving training. He or she will be advised to purchase twin twelve litre cylinders because it seems that ‘that is standard practice’. However, these tanks weigh around thirty five kilos with the harness and this is far too heavy for those with a smaller frame. Another popular choice is two ten litre tanks – though some people find these are too short to rest on a bench when sitting on a boat waiting to dive. Many opt for twin seven litre sets but feel that the amount of gas it is possible to carry is too little for much of the diving they expect to do. Another alternative would be to buy twin sevens rated for three hundred bar pressure – but these are difficult to fill completely at most filling stations.

If you search around you will see that there is another option that is fairly new and not yet popular – twin eight and a half litre tanks. Being as long as a twelve two of these tanks are just as heavy as a single fifteen. This setup will allow the adventurous diver to extend their range considerably while still having the added benefit of twin tank redundancy – and their weight will be easier on your back!

It is sensible to give expensive gear a try out before committing to buying. If you can borrow or rent items before committing to the purchase you can save costly mistakes, or find that your enjoyment of the sport is considerably enhanced.
