PADI Rescue Diver – Worth Doing?

PADI Rescue Diver = Confident. Responsible. Prepared.  A bit tired as well!

Book your EFRRescue Diver Course in May and receive a £30 voucher to spend in store when you have completed your course.

Divers who have completed their PADI Rescue diver always talk about the course being the most rewarding and often most demanding PADI course they complete.  Many instructors also tell us how much they enjoy teaching it.

PADI Rescue Diver Course

As I woke up surprisingly early on my first days holiday, I had distant school memories where the word rewarding was often linked to hard boring work.   With this in mind I worked across the hotel to the dive centre to start  4 days EFR and Rescue Diver training.   Hard work maybe but boring never!

After the paperwork was completed I was handed two brand new manuals, for EFR and Rescue diver respectively.  The theory and practical skills combine perfectly on this course which made the knowledge reviews great markers for progression during the course.  You really learn some amazing skills really simply.

What do you learn

-Causes of diver emergencies
-Accident management -Identifying a diver in need
-Common equipment problems -Diver rescue procedures
-First Aid and injury treatment -Missing diver procedures
-In/Out water rescue skills

First off you learn about the psychology of Rescue and the important question that is re-enforced over the course. Protect yourself first! Don’t become the 2nd victim.  The importance of of preparation should be familiar with all divers of any level, but in the Rescue course we take this further.  Do you have the right equipment for emergencies?  before I took the rescue course this was something I never really gave to much thought to.  Now I know exactly what is required.

CPR and First Aid

PADI Rescue Diver EFR

The EFR Primary and Secondary Care elements of the course were really interesting and provided me with skills that I know are not just for diving but can be used in everyday life.    Some of the primary and secondary skills you learn; Scene assessment, CPR not a skill to be taken lightly as those who have completed CPR training will know, Bleeding management and Spinal injury management.

This knowledge brings with it a confidence that I am now prepared to respond to an emergency correctly when needed .

Water Skills

The practical side of the course revolves around a number of rescue scenarios revolving around skills used to help either a responsive or non responsive diver at the surface or underwater.   Prepare to get tired!  Yes this is a pretty intensive part of the course but at the end of each day the tiredness is only second to the contented feeling you have.   Top Tip = Try and choose the smallest lightest person on the course as your buddy.  Thanks to my willing victim Nat!

One of the hardest parts of the in water rescue skills can be remembering the correct order of the actions you need to complete.  In fact you may even find you won’t notice how physical it is towing an unresponsive diver as you’ll be concentrating on providing rescue breath, supporting airways and removing equipment if the situation requires.  Each scenario though varied essentially boils down to the same core skills that by now your have learnt and are starting to master.

It’s an incredible course that gives you vast amounts of confidence while having fun and in quite a few circumstances leaves you looking like a rabbit caught in headlights!

Joking aside, the PADI Rescue diver course is a great course and takes you personally further as a diver as you now have the confidence and preparedness that can really transform your outlook.   I can wholeheartedly recommend it.

Ready for the challenge?  Contact DiveStyle now and get started on the course you’ll love.

Famous Scuba Divers

People Who Have Made A Difference – Plus Some Celebrities That Dive

Famous scuba divers. Almost everyone has heard of Jacques Cousteau. He is probably the most famous diver in the history of scuba diving. And rightly so since he is the one who made it accessible to the average person.

But who else has strapped on a tank and made a difference in the sport? Well, let’s find out…

Photo by Tom Ordway, Ocean Futures Society; Courtesy of KQED
Jean Michel Cousteau founded the Ocean Futures Society

We’ll start with Jean-Michel Cousteau (1938 – ), the son of Jacques Cousteau. He is listed as thefirst certified diver in the world.

It is famously reported that his first dive was when he was 7. He was thrown overboard by his father with his father’s newly invented aqualung strapped to his back. Today he is probably the most recognized environmentalist in the world. He is president of the Ocean Futures Society (a nonprofit marine education and conservation organization) and an influential filmmaker.

Let’s go to Hollywood for some famous scuba divers. Lloyd Bridges (1913-1998). For the younger set, he is the father of actors Jeff and Beau Bridges. He introduced scuba diving to millions of people with his TV series “Sea Hunt”which aired from 1957 to 1961. In this series he played a Navy frogman turned undersea investigator.

Many recreational divers entered the sport because of this series. Bridges was also NAUI’s first honorary instructor member.

Zale Perry is another entry with a (partly) Hollywood angle. She played the resident damsel in distress in the Sea Hunt series. Prior to this, she was a test diver for major equipment manufacturers. Zale Perry began her diving career in 1951 and is considered an authority on sport diving. She was key in the development of decompression chamber treatment for diving injuries and is now a member of the Diving Hall of Fame.

Lloyd Bridges in Sea Hunt

We’ll leave the Hollywood angle behind for now and focus on the more serious work of some famous scuba divers. Albert Tillman (1928-2004) along with Neal Hess founded the National Association of Underwater Instructors (NAUI) in 1960. NAUI is now the second largest certification agency in the world. Tillman also co-authored Scuba America with Zale Perry.

John Cronin (1929-2003) was co-founder and CEO of PADI. Along with Ralph Erickson, he formed this new professional diver training organization in 1966. PADI is the largest diving certification agency in the world.

Famous scuba divers also include Mel Fisher(1922-1998), better known as the World’s Greatest Treasure Hunter. He found the Spanish galleon, Nuestra Senora de Atochaand Santa Margarita on July 20. 1985. These ships sank over 350 years ago and contained over $450 MM in silver, gold and other artifacts. He is credited with opening the states first dive shop around 1950. He spent his life in various aspects of the dive industry (teaching, filming, treasure hunting).

Sylvia Earle (1935- ) is probably the best know female marine scientist. Nicknamed the “Sturgeon General” or “The Queen of Deepness” she is a National Geographic Explorer-in-Residence and a former chief scientist for NAOO (National Oceanic and Atmospheric Administration). At 3280 feet, she holds the record for solo diving. Earle is also one of the original inductees into theWomen Divers Hall of Fame.

Eugenie Clark (1922 – ), also known as The Shark Lady, is known for her research on sharks and poisonous fishes. She has caught and studied over 2,000 sharks. With her research, she has given the world a better understanding of why fish behave the way they do.

Let’s end with a few celebrity divers. Not because they contributed anything to the sport, but because it’s fun: Tom Cruise, Tiger Woods,  James Cameron, Lauren Hutton, Bill Gates, Kathleen Turner, Paris Hilton, Gene Hackman, Nikki Taylor and Penelope Cruz to name a few.

In fact, Shape magazine recently ran an article saying that some celebrities such as Jessica AlbaSandra BullockKatie Holmes, and Nina Dobrev took up the sport as a form of physical fitness. It is the new celebrity fitness trend. The magazine reports you can burn up to 400 calories in 30 minutes of diving. Not too shabby.

As Tiger Woods so famously put it, maybe one of the attractions of diving for famous people is: “The fish don’t know who I am.”

This list is by now means exhaustive. It would take a book to write about all the people that have made contributions to the sport of diving. But, hopefully, it has given you a good introduction. For information on more scuba divers who have made a difference to the sport, check out the International Scuba Diving Hall of Fame.

5 Scuba Diving Bad Habits and How to Avoid Them


5 Scuba Diving Bad Habits and How to Avoid Them!

Scuba Diver Bad Habits

Its that time of year again! Time to dust of your scuba gear and get back into the water after 6 – 8 months of watching the weather, or is it?

We are fortunate to dive all year round, this means that our skills are kept sharp and our kit is kept sharp fully serviced, but for many this is not the case.

Each year as the scuba season explodes we always see some classic examples of scuba diving bad habits – from experienced divers no less!

So here a 5 ‘Bad Habits’ to try and avoid for the 2014 season

Bad Habit #1 – Skipping the buddy check
You ask your buddy, “You ready? Yeah? Let’s go diving.” Everything seems fine until you roll off the boat and discover you forgot your fins, your buddy’s tank is loose, or something even worse.

Forgoing a buddy check takes a shortcut on safety and increases the chance of having to solve a problem in the water.  You can learn more about avoiding and adapting to problems in the PADI Rescue Diver course, but the best thing to do (as we teach during the Rescue course) is prevent problems before they begin with BWRAF .

Bad Habit #2 – Shooting fish butts
There were some very expensive camera rigs on board, but an expensive setup doesn’t guarantee good photos. Especially when the photographer doesn’t know underwater photo basics, or fails to practice good marine life etiquette.

I saw one diver with a top-of-the-line camera system taking a photo straight down over a coral head. I’m no photo pro, but I learned in the Digital Underwater Photography online course that shooting straight down on your subject tends to produce flat, uninteresting images. Perhaps it was an avant-garde shot.

I watched another diver race from one critter to the next – chasing off marine life as he went. The dive guides tried to counsel this diver, but he wouldn’t listen, “This is how I always dive” was his reply. I wondered how many pictures of fish butts he had… and how he ever found a dive buddy!

Bad Habit #3 – Not wearing the right exposure protection
Every time I show up at at a tropical dive destination, other divers laugh at me for wearing a 5mil wetsuit and a beanie cap in 28C/82F water. But by wearing the exposure protection that’s right for me, I never have to cut a dive short because I’m cold.

After a few years diving regularly in California I tried the PADI Drysuit Diver specialty and wondered, “why didn’t I do this sooner?” I imagine the cafe owners on Catalina Island wondered what ever happened to that girl who asked for cups of hot water to dump down her wetsuit.

#4 Wearing the incorrect amount of weight
Picture a brick, the kind used in home building. Imagine carrying it around with you all the time – taking it up stairs, trudging up a hill, etc. Having extra weight on board means your body has to work harder; your breathing will be heavier and so on.

When teaching the Peak Performance Buoyancy specialty course, that brick weight is (on average) the amount I take off a diver’s weight belt. New divers often wear excess weight, and get used to carrying it around. But there’s a major downside – too much weight can lead to excess air consumption. The extra weight means the body has to work harder to push through the water, and on top of it many divers swim continuously to keep themselves buoyant. All that extra effort drains your tank faster than necessary.

Drop that brick and extend your dive time! Review your open water materials for how to do a buoyancy check, or ask your instructor about the Peak Performance Buoyancy specialty course.

Group of Divers

Bad Habit #5 – Neglecting gear service
Woe is the diver who pays half a month’s salary to go on the dive trip of a lifetime and has an equipment problem. When maintained properly, dive gear can last for years. Ask your local dive center about the Equipment Specialist course. You’ll get to know your gear and learn how to perform basic maintenance yourself. That said: some equipment service must be performed by a professional. Use the gear locker section of your ScubaEarth profile to keep track of when your gear gets serviced.

The PADI TecRec Range – When One Tank Is Not Enough!

The TecRec Range


Technical diving is scuba diving’s “extreme sport”, taking experienced and qualified divers far deeper and further than in mainstream recreational diving. Technical diving is marked by significantly more equipment and training requirements to manage the additional hazards this type of diving entails. Tec diving isn’t for everyone, but for those who want to be explore further, the TecRec courses are the answer.

Diver Levels

Most of the names of the courses in TecRec range include a number (eg Tec 40). This is an indication of the maximum depth in metres intended for a diver certified at this level. As a general rule, each course includes four dives. 

Discover Tec

This short session allows divers to give technical diving a try. It does not result in a certification, but lets a diver experience wearing the extra gear involved in technical diving and understand the rationale behind it.

Tec 40

The entry point into the technical range, Tec 40 provides a transition from recreational to technical diving. Although the use of full tech gear (doubles and wings) is preferred, it does allow modified use of recreational gear in some situations, provided the diver has two separate regulators, with one of the first stages fitted with a long hose. Double and single rigs

(For example, a main cylinder and pony cylinder combination). The intended working limit for a diver at this level is 40 metres/130 feet with up to 10 minutes of non-accelerated decompression. They may use any EANx mix with up to 50% oxygen content or air. To enrol on the course, a diver must be the equivalent of a PADI Advanced Open Water diver, with an EANx Diver rating and have deep recreational diving experience.

Tec 45

The diver must use full ‘standardised’ tech rig, including wings and doubles plus an additional deco cylinder (note that side mounted cylinders are an acceptable alternative to back mounted doubles throughout the TecRec range). The course allows the diver to go to 45 metres/145 feet and make accelerated decompression dives using any mix of EANx or pure oxygen. A diver must have the equivalent of a Tec 40 rating to enrol on this course.

Tec 50

This course represents a high level of competency for a technical diver. Although the option exists to make the last dive of the course using trimix, it is intended as an air/nitrox rating and by the end the diver can dive to a maximum of 50 metres/165 feet and make extended, accelerated decompression dives.

Tec Trimix 65

This course opens up the advantages of trimix to the diver, and divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression, using any trimix with an oxygen content of 18% or more. They can dive to a maximum depth of 65 metres/210 feet.

Tec Trimix

Trimix Divers

This course lets the diver go deeper, opening up the option of using travel gases and trimix with less than 18% oxygen content. Dives made during the course can be as deep as 90 metres/300 feet. Once qualified, the diver can start to explore deeper; for this reason there is no numbered suffix after the course title as in the rest of the range — there are no limits placed on how deep the diver can go after training, providing they build their experience gradually.

Gas Blender


The Gas Blender rating certifies the holder to mix enriched air or trimix for divers to use in recreational or technical diving operations. Courses for this level are conducted by Gas Blender Instructors.
