At the end of our dive, just before re-entering the boat, a group of 15 dolphins shows up and are willing to play. Resulting in exiting 4 minutes and great video!

JMG asked:


A submerged scuba diver looks up toward the calm surface of a freshwater lake and notes that the Sun appears to be 21° from the vertical. The diver’s friend’s standing on the shore of the lake. At what angle above the horizon does the friend see the sun?

Clearly, being many feet under water for an extended period of time is not something humans were designed to do. But the art of scuba diving has opened up the possibilities - allowing us to journey where we were previously unable to explore. Of course, the reason that scuba diving is successful on this front is because of the scuba diving equipment that renders us physically able to stay underwater.

Scuba diving can be an amazing experience and one - for obvious reasons - that many find themselves addicted to after just the first time. But diving safely depends not only on the skill of the diver, but on the dependability and proper use of extensive scuba diving equipment.

The first layer of scuba diving equipment is that which covers the diver. The wetsuit, made of a thin layer of synthetic rubber and lined with nylon, forms a protective barrier between the diver and the water. The diver’s skin is kept completely dry and the material of the wetsuit actually traps body heat against the skin guarding against hypothermia. It is important, for this reason, that the wetsuit be as snug as possible against the diver’s body. In addition to the wetsuit, the scuba diver also wears flippers as part of their scuba diving equipment that allows them to maneuver effortlessly through the water.

Of course, the scuba diving equipment that most people associate with scuba is the oxygen tank. The oxygen tank is the most essential piece of scuba diving equipment as it allows the diver to stay underwater for extended periods of time. The oxygen tank is carried on the back of the diver; its size depends on the length and time of the dive. Most tanks also include equipment that allows the divers to closely monitor the amount of oxygen they have left so that they can resurface safely.

The facemask - another piece of scuba diving equipment - is placed over the mouth, nose, and eyes of the diver. Oxygen is pumped into the mask allowing the diver to breathe. The mask also enables the diver to see underwater without obstruction.

Scuba instruction of any kind will include comprehensive lessons on the safe and effective use of scuba diving equipment. It is imperative that scuba divers - beginners and veterans alike - use their scuba diving equipment respectfully and in complete accordance with operating instructions. Using these safety measures will ensure that you have an enjoyable - and memorable - scuba experience.

James R asked:


I was going to take a SCUBA diving course over the summer, and i was wondering if it is fun, and if it is something good to do over the summer. Also, is it worth the money, because the course is like £300
Finally, what can i expect on the first lesson, as i dont want to be stuck in a room all day learning about the equipment, on the first lesson, will i get to go in the pool with all the gear on?

Scuba diving vacations are a great escape from the everyday world. However, there are lots of options to choose from and they can get very expensive.

You can book each portion of the trip separately, you can purchase a vacation package, you can stay on a liveaboard, stay at an all inclusive or any variation of these options.

However, there are ways to reduce the cost of that long-awaited vacation. In this article we are going to explore a stay at an all inclusive resort in the Caribbean that includes scuba diving.

They can be a great money saver but there are some pros and cons to consider with this option.

Pros

* Don’t have to worry about money while you are there

* Usually cheaper than purchasing everything separately

* Stress free: No decisions to make about where to go for drinks, dinner or diving

* Usually a party atmosphere (can be a con too)

* Security

* Activities and entertainment are included (sometimes diving is included also)

Cons

* Usually big resorts; grounds and dive boats can be crowded (ever have to go out at 6 am to reserve a lounge on the beach?)

* No incentive to leave the resort and experience the local culture

* Have unexpected expense of going out if you don’t like the food and/or drink

* Service is sometimes lacking since tips are already included (we always tip anyway, even if the policy is supposedly not to

* Not all islands have all inclusives, so island choice is limited

You just have to decide what is most important for you. For instance, if you like smaller resorts and small dive groups, than an all inclusive resort may not be for you.

Most all inclusives include non-motorized water sports in the package. However, while most resorts offer scuba diving, you usually have to pay extra for it. If the resort does offer scuba diving in the price, you can save a significant amount of money.

If you pay for your diving at the resort, my experience has been that prices are pretty much market prices. If you do multiple dives you can usually get a discount, but that is typically the case for non-resort dive shops too.

If there are a few divers, you can usually negotiate a better price. Many places we have been allow you to purchase a dive package (say 15 dives) and split the dives among the different divers. It has always worked out well and we saved a fair amount of money.

Popular All Inclusive Destinations

Probably the most popular places (or at least those with the most resort choices) for an all inclusive Caribbean scuba diving vacation are the Dominican Republic, Jamaica and Mexico’s Yucatan peninsula, including the ever popular Cozumel. In my opinion, Cozumel is the hands down winner as far as diving.

High End/Low End

There is an all inclusive resort to fit every budget. You just have to decide what you want. What’s more important to you? Would you rather have gourmet food and premium drinks or would you be happy with lower end offerings and more money in your wallet? The answer can be different for each trip.

No matter where you go and which level of service you choose, it is hard not to have a good time. So pick a place, pack your scuba gear and get going!

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.

We are a couple wanting to go scuba diving together in Egypt. We’ve only done a few dives each so don’t want anything too deep at this stage. We would like a nice 4-5 star hotel if anyone can suggest this near dive sites too. Any info about where to fly in would help as well. A trip up the Nile would be a bonus!
