How To Get Certified In Scuba Diving

The first two steps in getting certified in scuba diving is to make sure that you are a reasonably proficient swimmer and you get medical clearance from your doctor to take up the sport. As for the swimming, you dont have to master every type of stroke. Scuba certification only requires that you are able to swim about 200 yards using any stroke you want and to be able to float or tread on water for about 10 minutes. If you are in good general health and are comfortable in the water, then you should be able to scuba dive without any problems.

There are about 1,900 professional scuba dive centers in North America alone and your local ones should definitely be checked out. Most will run basic certification programs on a regular basis. These centers or shops should be listed in the yellow pages and you can also check with websites of some of the major scuba diving certification agencies such as PADI or NAUI as they will also have listings. Sometimes scuba diving courses are offered at universities too.

Make sure that the course you are interested in taking as well as its instructor are certified with one of the major scuba diving training agencies. This will ensure that you get proper, safe training for both the technical background knowledge and practical skills required for certification as a scuba diver. You also want to end up with an internationally recognized certification card if you want to go scuba diving at various locations around the world.

Some vacation resorts offer resort courses lasting a day or two which offer beginners some very basic training in order to try out scuba diving. These are not certification programs. Full certification programs involve classroom work, exams, practical skills sessions at a pool and usually about four open water dives in the sea (lake or ocean). The duration of the classroom work and pool sessions vary from a very intensive weekend (with advance reading) to once a week over several weeks. The open water dives will usually take two more days. Dive centers located in the tropics also offer basic certification programs that last several days to a week. Although the intensive weekend programs are quite feasible, many feel that basic scuba diving courses spread out over a few weeks will help beginners learn the skills better. Scuba diving does involve new skills and to learn them all during one full weekend may be too much for some people.

As for which scuba diving certification training agency is the best, there isnt any one recognized organization that is better than another. PADI is the most popular in the world but not necessarily better than NAUI or SSI. NAUI course are often more technical in the classroom than those offered by PADI but both will adequately train you to be a scuba diver. The more important factor would be the individual instructor and your own effort during training/studying. In fact, many scuba diving instructors have certifications from several training agencies.

For people living in the more northern regions, there are a few possible routes to take in order to obtain certification. One can travel down south to the tropics and do the entire basic certification course down there in warm weather. However, this will take up a good portion of a vacation since reading, classroom, pool sessions and open water dives all must be done during that time period. A second option is to take the entire course including the open water dives back in home territory. This usually offers beginners the most time since courses can be spread out over a few weeks. However, the water up north is not as warm as in the tropics and the scuba diving could be seasonal. A third option is to take all the classroom and pool sessions back home and then go down south to do the open water dives in warm waters. Many people have taken this route. Your instructor back home will give you a referral letter to bring down to an instructor located down south who will oversee your open water dives. This is a good combination of taking ample time back home to practice the skills in the pool plus getting the classroom work out of the way followed by having nice warm water to dive in for the open water dives. One thing to be aware of if considering this option is to make sure that your travel to the tropics for your open water dives is not too delayed after finishing up with your pool sessions at home. If too much time has elapsed, one could easily forget the skills learned in the pool by the time a vacation comes along.

The underwater world has so much to offer and only a small percentage of the worlds population will ever have the privilege to see it in person rather than on television. Become one of these individuals who will have the honor of exploring the oceans by getting certified in scuba diving.

Water Everywhere But Not A Drop To Drink

water, water everywhere, but not a drop to drink! This is not a scenario in the ocean, but on land, where global warming has brought about massive flooding, including water reservoirs. Occasionally, there is no electricity as well because the local substation is inoperable due to water flooding. What can we do now? Here is a useful suggestion.

Rebuild our houses with underground water reservoirs. And make it big enough to store water for at least a months supply. House compounds should also be paved with a layer of surface, either natural or syntactic materials to trap and filter run off rain water. The filtered water should then be channeled to the underground water reservoir by way of pipes and pumps. The reservoir will be able to accommodate pipe water as well as rain water. Rain water might not be that forthcoming during dry weather season, so if you fill the reservoir with three quarters full of pipe water, you would at least have water during emergencies. There should also be in place an automatic control system for the water so that it would be able to function without supervision. Present day telemetry devices are intelligent enough to make your automatic system trouble free. You can even wire it in such a way that you can check on its condition while away from the house. There will be electric pumps installed to channel the inflow and outflow of water. In case of emergencies, an auxiliary gasoline fired electrical generation set should also be wired into the pumps. It should also be sited at a level where it would not be easily flooded by water, and in this respect, it would be advisable to site it at ceiling levels. This is a very basic system and other items can be affixed to make it a comprehensive system.

This is an idea that I have suggested in my book entitled 'Invention: The moment before the spark came' published some time ago by LuLu.com and if you are interested to see my other ideas, you can go to my website at http://www.aircoast.com
