I was sitting at the Chart Room Bar at our marina chatting with Geno and Kelly, two of the owners of Latitudes restaurant, and anticipating, quietly, the arrival of a “Key West pinks” shrimp PoBoy. Kelly politely introduced me as Captain B.K. to the newly arrived rookie bartender who in turn greeted me and after the initial fact finding rhetoric, she announced that she was a certified diver and her lifelong dream was to “swim with sharks”, and could I suggest a dive master to help her accomplish this, in my opinion, somewhat reckless, feat. |
It would take a moment to respond to her request, having to mull over my conflicted feelings about this idea having just come from the dock where a six foot bull shark had been brought in by captain Dane Karcher and guests. (Picture above) Of course I admit my own bias, much like those that feel skydiving is wacky and voices that opinion with questions such as, “Why would someone jump out of a perfectly good plane and plummet earthward at 120 miles per hour?” Being a captain and guide I have long thought my job was to keep people in the boat, safe, sound, dry with fish securely hooked to the other end of our tackle and a well stocked cooler. Having released many large sharks from our lines alongside the boat, after they’ve gobbled the fish we wanted to catch, I find the idea of being in proximity of a 250 lb shark without gunnels between it and I, somewhat disconcerting. But apparently that is not a bias nor a concern that divers share and consequently dress up in black wet suits, vaguely resembling a seal when viewed from below, strapping on buoyancy devices, breathing devices, weight belts, knives, spears, cameras, tanks, regulators, and jump off perfectly good boats and descend into the shipping channel near Egmont Key to spot stealthy Bull, Hammerhead, or other toothy prehistoric predators or dive down to a reef loaded with shark prey. In fact they report that diving experiences, for the most part are absolutely relaxing and exhilarating. I admit being a fan of underwater photography, as long as someone else is taking the nose to nose pictures of a Bull Shark. Having mulled thoroughly I responded, “Yes, I do”, and then immediately wondered if I should have a disclaimer signed. |
So what is the allure that seems to grip divers and novices alike about gliding along under the surface of the water? Some things are the obvious visual panoramic experiences whereas some souls relate that they feel as if they've left earthly bounds when in the undersea climes. In addition there are delicious dinners awaiting should you master the spear gun and track down a nice snapper like the one shown here by mate Austin Fraley of Quality Time Charters.The following description of the allure of diving comes from work penned by poet laureate Gary Henkel who is also a contributing writer for this article.
Weightless flight. For a while set aside your
earthbound self and travel like an angel free
from the cares of the mortal world.

In an interview with Gary and his friend and Dive Master and rescue diver, Captain Bill Nelson I was introduced more thoroughly to the complexities, training, and rewards associated with scuba diving. The more I listened and read the material they supplied for me; I began to see that to dive safely and successfully would take time, patience, training, endurance, and confidence by anyone that wishes to become a certified scuba diver.
Firstly, before slipping into the water with a deadly spear gun and skewering dinner, each would-be diver must complete a rather rigorous training course and testing to receive the desired certification. A qualified dive instructor, as Gary described, will |
| guide, cajole, and challenge you during repetitive dive classes and assuming you survive mentally, perform to standards physically, and pass, you will receive a dive certification card allowing you to dive worldwide and create your own dream vacations in exotic places with others of like mind. You may become so proficient you will soon be enjoying your own catch employing a culinary technique of your choosing. |

The balance of this article is penned by Gary Henkel as his description of the dive training experience. In future articles we will relate reports of divers from locals around the reefs, wrecks, and seas of the world. In addition, Dive Master Captain Bill Nelson will share dive tips, locations, and techniques. I welcome submissions from our readers or divers, scuba, snorkel, free, or other. Pictures are appreciated and will be posted appropriately and credit given. |

Dive into Diving – Gary Henkel |
 |
Sounds exciting? While diving can be one of the most exciting adventures of your life, without proper training diving can be the last great adventure of your life. Not to scare you, but you are breathing underwater under great concentration, weight and compression of a medium not know to honor the foolish.
Taking a dive class is not a pass fail situation. Mother Ocean will look at you diving and be able to tell exactly how well you did in your dive class. I say this, again not to frighten you off, but to ensure you exercise all due diligence and prepare to really understand and absorb the materials your dive instructor goes over with you. I’m not going to go into all of those details here. Just remember, you have a tank of air on your back, something called a “buoyancy control device,” wrapped around you, a device in your mouth called a regulator, a dive computer, and you are the one most and sometimes only responsible for your safety. Old Mother Ocean will diligently check out each piece of your dive equipment in search of any deficiencies, and usually in the least favorable moment let you know there is a problem with your equipment. Again, nothing said here is to frighten you away from diving. Learning to dive, however, requires your complete attention and willingness to wave happily at Old Mother Ocean. |

Just one more thing before we go into what happens in a dive training class. Did you know that air is heavy? You walk around in air all day. The wind blows on you (of course, in a hurricane you have an idea that moving air can be very vigorous) but did you ever think that air is heavy. The weight of air is approximately 14.7 lbs per square inch. Air is what you breathe and what you fill tires with. There is no air in a light bulb (a vacuum). Ever watch a light bulb explode?
We don’t feel the weight of air (‘air pressure’) because we are filled with air (some with more hot air than others) and so the interior and exterior air pressure are the same or (equalized). To put it simply, the weight water pushes against you at 33 feet below the surface is the same pressure air that pushes against you on land. Now, you have air pressure pushing on you and at 33 feet the equivalent of an equal amount of pressure. So, at 33 feet deep, you have 2 atmospheres of pressure pushing on you. 99 feet equals 3 atmospheres of pressure.
You all have most likely watched movies of submarines diving deeper and deeper until the water starts spurting in, and the danger horns blare (different for each particular navy) and finally, no more submarine. Dive too deep, don’t come up at the right time, come up too fast, Old Mother Ocean is waiting!
So what happens in a dive class? First, there are classes on land to teach you the ins and outs of all the various pieces of equipment you will be using. Then there will be tests. (And for those who do not pass, there will be mandatory flogging). |

Once you have demonstrated sufficient knowledge and understanding, you will go to a pool where you must demonstrate the ability to swim, float, and enjoy the water. You will also demonstrate, by swimming, you have the physical condition and stamina to meet the rigors of diving. Once you have passed the physical endurance tests, you will then begin to experience the wonderment of putting on all of the still mysterious dive equipment. Finally, after what seems an absolutely endless period of time, you will experience your first breathing under water (something you could never do before, even though you may have tried). Once you have proven you can breathe underwater (even if in a swimming pool) you are then ready for your first open water dive experience.
Water has weight. Water has currents. Water often has its own relentless agenda to take anything or anyone in it where water wants to go. Water does not ask permission to change its dimension or direction. And once you are in the water, guess what, you had best have plans made to deal with the situation. Usually, on your first open water dive you will be taken to what is usually a safe spot. However, if you are willing to jump out of a perfectly good boat, you and your dive instructor and fellow students will need to be totally aware of where you are, what the water conditions may be, what to do in case a big, hungry fish has missed its lunch and what big and extremely curious fish with big teeth are likely to do (if not eating you). |
Well, finally it is over. You have passed all of your tests in the classroom, in the swimming pool, and in the open water, and you have not been eaten or squashed, you may reside now in an underwater heaven. Do you now start to disregard all that you have learned and experienced?
Experienced divers constantly review the technology of diving. Success in diving requires eternal vigilance. There may be old and careful divers, but there most likely are very few old and careless divers.
Learn what you have to. Learn to dive. Learn to enjoy diving.
