The Motor Reef Wreck, La Parguera PR The Motor Reef Wreck, La Parguera PR
ginovega - 9 days 23 hours ago.
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...

Scuba Diving Courses, you just don’t know what you don’t know. Scuba Diving Courses, you just don’t know what you don’t know.

It does not matter if you are just a bubble blowing beginner or a super slick dive pro everybody knows that professional Scuba diving courses are what you need to learn important skills to have fun safely under the water. But what are the top three questions you have to ask of your prospective instructor or dive centre before signing up for any Scuba diving courses? To experience the underwater world is truly an experience unlike anything non divers can imagine, and throughout you diving career ...
PADI Open Water Diver Course Revision - Training Bulletin - Fourth Quarter 2013 PADI Open Water Diver Course Revision - Training Bulletin - Fourth Quarter 2013

You can begin teaching the revised course as soon as you access the updated material and have familiarized yourself with the changes. This bulletin and the Fourth Quarter 20...
Part 5 – Your Lungs & Scuba Diving: Easy, Breezy, Breathing! Part 5 – Your Lungs & Scuba Diving: Easy, Breezy, Breathing!
DiveWithMia - 11/26/2013 1:38 AM
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...
WHY we NEED dive tables!!! WHY we NEED dive tables!!!
Divingleo - 11/03/2013 9:20 PM
WHY ?? do we need DIVE TABLES ??!!! Before we can discuss dive tables, we must first understand why we need them. Henry’s Law tells us that the amount of gas that will dissolve into a liquid at a given temperature is almost directly proportional to the partial pressure of that gas. What does this mean? Basically, liquids have a certain amount of gas dissolved in them. For example, a glass of water sitting on your kitchen table will have gasses dissolved in it. The atmosphere is comprised primari...
WHY is certification IMPORTANT??? WHY is certification IMPORTANT???
Divingleo - 11/03/2013 9:10 PM
Why is certification important? Why is certification important to us? Many people wonder why certification (a "C" card) is required. To fully understand why certification exists lets look into diving as a sport…. As with driving a car, diving can be done safely with proper training, and can be very dangerous for the untrained. For example, there are depth and time limits associated with deep dives that will provide us with a reasonable margin of safety, if followed. As with car rental agencies, ...
Diver Dave & the Denver Aquarium – Episode 7 (Shipwreck Part 2) Diver Dave & the Denver Aquarium – Episode 7 (Shipwreck Part 2)
dontdiveenuf - 11/02/2013 6:36 AM
In which our hero learns the difference between theory and practice - Part 7 of Several Installments. My 4th Shipwreck dive – feeding the Sawfish was the main course on the menu, with an appetizer of scrubbing down the window in Section 4. Bill M was my trainer, with Bill H as backup. Wiping down the main window was bit of an adventure – Bill M positioned himself with the fending tool and swam beside me as I pulled myself along. Since this is the main window that looks onto the arena, the sharks...
Diver Dave & the Denver Aquarium – Episode 6 (Shipwreck Part 1) Diver Dave & the Denver Aquarium – Episode 6 (Shipwreck Part 1)
dontdiveenuf - 11/02/2013 6:29 AM
The Sharp, the Sleek, and the Nosy - Part 6 of Several Installments. Oddly enough, the Shark tank (“Shipwreck”) is one of the most tranquil exhibits at the Aquarium. From the Dive Platform there are two reef exhibits to left and right (Sections 1 and 2), while the open ‘arena’ where the sharks are stretches out in front (Sections 3 and 4). While the sharks and Great Barracudas can (and do) swim right over the dive platform and the reef areas, it’s considered bad form for a diver to be free swimm...
Diver Dave & the Denver Aquarium – Episode 5 (Reservoir) Diver Dave & the Denver Aquarium – Episode 5 (Reservoir)
dontdiveenuf - 11/02/2013 6:03 AM
Fresh Water, White Hunger. Part 5 of Several Installments. Reservoir is a relatively narrow exhibit – about 17’ deep by 20’ wide, and full of catfish, gar, pike, sturgeon, and bass. Setting up the siphon was much the same as for the other exhibits, although we control the pump, rather than having to call Life Support to turn it on and off. As I was getting in with my instructor, Sara W, we noticed one small gar lying on the bottom step, right next to the riser. It was so still we were concerned ...

Diver Dave & the Denver Aquarium – Episode 4 (Pathways) Diver Dave & the Denver Aquarium – Episode 4 (Pathways)
dontdiveenuf - 10/26/2013 6:27 AM
In which Diver Dave finds himself between a rock and a hard place. Part 4 of Several Installments. Diving in the Pathway exhibits is very different– they’re very shallow (no more than 7 or 8 feet deep) and very narrow, much too narrow for standard scuba gear, so we have to use a ‘hookah’ system: two tanks mounted on a cart, with about a hundred feet of hose leading to our regulators. After positioning the cart so that we can see the air pressure gauges thru the windows, we climb over the acrylic...

dontdiveenuf - 10/26/2013 5:52 AM
In which Diver Dave encounters mermaids without the benefit of hallucinatory influences. Part 3 of several installments. Diving in the Dining Room is a fairly quiet affair, but it has its own unique challenges. All of the critters are fed by the Aquarists at the surface, so the divers only need to scrub and siphon. It’s the only large tank that we have to enter from the 2nd floor, so we parade thru the exhibit hall in our wetsuits, to the delight of the kids (and young at heart). Past the ‘Staff...

In which our hero embarks on the long wet road to Volunteer Diverhood at the Denver Downtown Aquarium. Part 2 of Several Installments. Having proven my mettle in the Dining Room exhibit, I was now eligible to begin the DTAQ Diver Academy program, along with being committed to a minimum of two dives per month for a minimum of six months when I completed the course. Diver Trainees are expected to start their training with dives in the smaller River tanks, before progressing to the larger and more ...
Snorkeling vs. Skin Diving vs. Freediving Snorkeling vs. Skin Diving vs. Freediving
Greg - 10/23/2013 7:10 PM
Did you know... Snorkeling is the act of floating on the surface while utilizing a mask to see underwater, a snorkel to breathe while keeping one’s face submerged, and a pair of fins to move about the surface. Skin Diving adds submerging and swimming underwater to the activity of snorkeling. This may or may not include a weight belt and a wet suit. Freediving greatly alters the act of skin diving by using advanced breathing techniques, efficient movements underwater, and specialized equipment – ...
Scuba Diving with Underwater Metal Detectors
Scubablog - 10/20/2013 9:55 PM
For recreational scuba divers, the underwater world is nature in its purest form. Nothing offers more splendor and bliss than exploring the pristine beauty of coral and reefs, schools of fish and all of the marine life that inhabits the sea. Some divers enjoy underwater photography, others are searching inside caves and shipwrecks and others […] The post Scuba Diving with Underwater Metal Detectors appeared first on Scuba-Blog.com....
Altitude Diving Altitude Diving
Divingleo - 10/14/2013 10:25 PM
Following is a list of tips to remember when Altitude Diving. 1. Any dive between 1000 feet and 10,000 feet is an Altitude Dive 2. There is relatively little test data for altitude diving, flying after diving or driving to altitude after diving. 3. At sea level, the diver is surrounded by one atmosphere of pressure. At 10,000 feet, the pressure is .714 atmospheres (a 30% decrease in pressure). This is the same pressure change as 10 feet of seawater, which we know makes a big difference in our no...

DIVE LIKE A PRO / HYDRATION DIVE LIKE A PRO DRINKING ON THE JOB!! (Keeping yourself Hydrated) By: Tom Keeping yourself hydrated while diving is one of the most basic and important parts of diving that I just can’t stress highly enough to my friends and SCUBA students!! You may ask your self why?! I’ll tell you here: Being dehydrated can affect you in many ways while diving and the reason I feel is most important is that it can lead to DCI!But not only that but cramping and a lot of discomfort.
