PADI very distinctive specialties
diver_ralph - 5 days 10 hours ago.
Padi lists some of the following specialities on their website: I am interesting in finding the appropriate dive shop whereever it is to see if its worth trying for some of these additional certifications. Anyway, when I search myself online I can’t get a good hit finding the dive shop. Does anyone know where each or any of those distinctive specialites are located (web address) and post them? Thanks for any information you can provide...
Is it ok to pee in the ocean? Is it ok to pee in the ocean?
Greg - 6 days 12 hours ago.
Urine is 95 percent water with sodium and chloride ions. But urine contains something the ocean does not; urea. Urea is a water-soluble organic compound that helps the body rid itself of nitrogen. When urine and ocean water combine, the nitrogen in urea produces ammonium and acts as food for the ocean’s plant life. So go for it, you’re helping to save the ocean!...
Quote from Wesley C. Skiles on Extreme Cave Diving Quote from Wesley C. Skiles on Extreme Cave Diving
Greg - 15 days 20 hours ago.
I watched a show on Nova today called Extreme Cave Diving. Wes Skiles was the underwater videographer. I really liked what he said towards the end of the show: "You know I’m not sure how to go on in life if I wasn’t able to go to my church underwater. We go down in these places and we’re cleansed. When we come up from a dive...the pressure, the challenges, the difficulties, the conflicts...they’re gone. We come up from a dive and it is like, you’re reborn."...
Freediving and Deaths in Competitions Freediving and Deaths in Competitions
h2oman - 3/20/2015 10:05 AM
Many divers are adventurous souls. We like to eat some fish fillets after our long day on the water, trade some tall tails and plan the next outing. Sometimes we are frustrated when we can’t find anyone to dive with; sometimes we plan an outing and it seems like we have too many people on the boat, or that we invited just 1-2 too many divers. Some of us are very social when it comes to our dive time; we use scuba or freediving as a way to meet people and spend quality time with our friends. At t...

2014 Market Share of Scuba Certification Agencies (PADI, SSI, NAUI)
Greg - 12/12/2014 9:00 AM
According to the certifications added by scuba divers on, the following list indicates the percentage market share by each certification agency. I included all types of certifications, not just entry level certs. This data was collected from 21,273 divers. In the following list, I counted only once per agency per diver (ie: if a diver has 3 PADI certs and 1 DAN cert, I counted 1 for PADI and 1 for DAN): Worldwide 1. PADI: 55.6% (54.9% USA, 60.6% Outside USA) 2. SSI: 10.6% (11.4% US...

Here is some tips for the new diver. During my course I have seen people sign up for scuba for maybe a honeymoon or one trip. Folks this is not a one time commitment. This is a very important step in your life. When you do decide to embark on this journey. Enjoy every aspect of your experiences: whether they be in the class room, at a scuba park, at a lake, or ocean. Be sure to complete and read everything the instructor gives you. Practice your navigation on land. I like to go to the local foot...

Selecting a Training Facility
RAWalker - 8/16/2014 11:39 PM
Considerations for Selection of a Scuba Training Facility The sport of Scuba Diving has maintained a great record of safety while maturing from an elite sport to one that today enjoyed by the masses. This in spite of the fact that it is a high risk sport which allows people to enjoy a hostile environment. Those seeking to engage in the sport should not consider it lightly but with a serious understanding that it requires a great deal of knowledge and training to mitigate the risks and maintain s...
Kayak Diving in South Florida Kayak Diving in South Florida
kayakdan - 7/12/2014 6:39 AM
A kayak can help you reach dive sites as far as 2 miles offshore. They also are great exercise and expand the adventure of diving. Most dive sites in Broward County are within a 30 minute paddle of a kayak launch point. Necessary equipment includes the kayak (about $500), a paddle (about $45) and a coastguard-approved life vest (as cheap as $8). You will also need a dive flag mounted to the kayak ($10) and a lead line ($15 to $30) to pull the kayak along with you during your dive. Optional equip...
The True Cost of Scuba Diving The True Cost of Scuba Diving
Diver96 - 6/30/2014 4:51 PM
There are a lot of excuses for not becoming a diver. Number one on list is the time required to get certified. The second runner-up is that diving is expensive. These are common objections that I often run into. Cost seems to be the major sticking point, or is it? Diving is not cheap, but most adventure pursuits are not. In many places diving has taken on a status more in-line with "yachting" or "sky diving" than a something just about anyone participate in. Is this perception keeping potential ...
NITROX FOR Beginners
YKoach - 6/18/2014 9:02 AM
Although nitrox has been used for recreational diving for almost 25 years, it is still often misunderstood. As an instructor, I’ve found myself correcting countless students who are under the impression that nitrox enables a person to dive deeper than normal air — just one of the common misconceptions about nitrox diving. Although specific training is required before diving nitrox for the first time, these basic facts will help to make more sense of what it is and what it can do for you. What Is...

The Motor Reef Wreck (Photo taken by Pedro Padilla of Island Scuba, Guanica PR) The this site is located on Motor Reef, near Turrumote Cay, off La Parguera. The wreckage lies approximately five miles offshore, at a depth of 55 feet. Dives on the immediate site area revealed only a solitary but largely intact radial aircraft engine, with a single loose component lying nearby. The engine is encased in its cowling, and the propeller is attached and largely undamaged. Interestingly, the propeller bl...

What’s the most important rule in diving? Never hold your breath! If you remember one thing from your dive course, that’s usually it; but do divers really know why it’s so important? This is the final post in a series on air and its relationship to 5 key areas in diving that I’ve been writing about. If you haven’t already done so, take a peek at the introduction for some important background notes to ensure you understand the basics about air and pressure. These are directly related to what we’l...
Usefullness of an advanced class??? Usefullness of an advanced class???
Divingleo - 11/03/2013 9:23 PM
Why is the Advanced Class Useful? Why is the advanced class important? Does it create an expert diver? These are two questions that create a lot of controversy....Lets explore why.... The controversy, and answers to these questions, are intertwined in human nature. The controversy is related to the concept of an "advanced" diver being an "expert" diver. These are two different words that are used in two different contexts. The difference in context is often misunderstood. The word expert means a...
