The Self Reliant Diver

okt 11, 2011   //   by supernova   //   Blog, Crystal Divers, Divemaster  //  No Comments

Kitted up and Ready to go

As part of my continuing education in diving, not just the gaining of experience, I decided that I would rather enjoy undertaking the Self Reliant Diver Course, a relatively new course from PADI. My aim being that once qualified, I could complete the necessary qualifying dives to undertake the instructor qualification.

First let me say that self reliant diving is not Solo Diving. The self reliant dive training provides you with another skill set that increases your ability for self rescue, identify and anticipate problems before they become life threatening and equip you with the skills to extract yourself from a situation should it arise.

Diving without a partner requires you to be willing to make the required commitment to train and equip yourselves properly and to accept the added risks involved. You must have the right attitude and ability to dive independently. This is true in other adventure sport activities such a solo rock climbing.

Diving without a partner requires the right attitude and equipment. This includes, but is not restricted to redundant air sources, specific dive planning and management of independent diving problems and emergencies. However, no amount of redundant equipment can effectively back-up a diver’s brain better than another individual

In simple terms, responsible independent scuba diving is not for everyone; however it does have a place. So, who should develop self –reliant diving skills and why? The course will appeal most to photographers, videographers, traveling divers, wreck divers and TecRec Divers. This is by no means an exhaustive list and will appeal to anyone with the necessary course pre-requisites.

Having completed the necessary pre diving study and knowledge reviews, we traveled to Tulamben on Monday 10th October to complete the three qualifying dives. Having gone through some very thorough pre-dive planning and briefing we kitted up ready for the first dive. We were certainly carrying much more equipment that normal; redundant equipment that is either critical for survival or critical to the dive objective’s success. This included a backup 4.7 ltr cylinder, complete with regulator and SPG. This would allow us the opportunity to initiate an emergency exit from a life-threatening situation without undue stress and with a minimum of confusion in the event of a major equipment malfunction.

Entry for Dive One

During the first dive we were required to complete a number of skills, which were, with all standard and specialized equipment, conduct a buoyancy check at the surface, complete a 200m surface swim, demonstrate neutral buoyancy by hovering for one minute, perform a relaxed, nonstop 200 meter surface swim, demonstrate the ability to switch to a redundant air supply system, simulating a regulator free flow and breathe from the redundant air source for at least two minutes, perform a SAC rate swim by swimming for approximately five minutes at a level depth, recording the appropriate information for later calculation and deploy a lift bag or DSMB from the bottom. All skills were completed without issue and one skill that was practiced a great deal was switching to our alternate air source, which had to be done one handed and within thirty seconds.

 

Swimming without a mask

After our required surface interval, we kitted up again for dive 2. During this dive we would have to complete further skills, comprising of demonstrating time, depth and gas supply awareness by writing the depth and cylinder pressure on a slate at 10-minute intervals, swim at depth for at least two minutes covering a distance of at least 18 meters without a mask. We would also have to whilst continuously swimming, simulate an out-of-air emergency and change from our primary air supply to our redundant air supply system within 30 seconds, then breathe from the redundant air supply system for at least two minutes, complete two navigation exercises, perform a SAC rate swim by swimming for five minutes at a level depth recording the appropriate information for later calculation and deploy a lift bag or DSMB from the bottom. Again, one of the key components and something practiced repeatedly throughout the dive was switching from our primary to redundant air supply. Again, all skills were completed and there was even time to interact with the aquatic life, especially the turtle that seams to have taken up residency on the wreck.

Swimming without a mask

Ready to go our seperate ways

After lunch, we began our third and final qualifying dive. For this dive we were truly diving alone but it was not just a fun dive. The instructor gave us our briefing for the dive and set us our tasks. This was to demonstrate time, depth and gas supply awareness by writing the depth and time on a slate for each 20 bar of gas consumed, demonstrate turn around pressure and time limit awareness when either the pressure or time limit established during the briefing is reached by writing the time (if pressure limit reached first) or the pressure (if time limit reached first) on a slate, demonstrate navigational control and return to the exit with no assistance from the instructor and while continuously swimming, simulate an out-of-air emergency and change from your primary air supply to your redundant air supply system within 30 seconds At the conclusion of the dive we then had to deploy a lift bag or DSMB and ascend to the surface, stopping at 5 metres/15 feet for a three minute safety stop and most importantly surface from the dive within the established time frame and with no less than the planned pressure remaining in the cylinder.

Through the Wreck

The third dive was a new experience, diving alone and with no buddy. We have all no doubt at some time or other been alone for a short while but to do a whole dive alone was something new. What was noticeable during this dive was that you checked your dive computer more often than usual and you became more aware of your surroundings and where other divers were, just in case.

At the end of the third dive we had completed all the skill requirements and were now qualified as Self Reliant Divers. Twenty more self reliant dives and instructor qualification beckons. The benefits of completing this course are not about diving alone. It is about being self reliant, equipping you with the skills and knowledge to be a better diver, able to self rescue if the need ever arose. These are certainly skills that anyone should have and teaches you how to manage situations where you may be separated from your buddy for extended periods of time.

BEACH CLEAN UP IN SANUR

sep 23, 2011   //   by supernova   //   Interns Blog  //  No Comments

Clean Up the World is a community based environmental campaign that inspires and empowers communities from every corner of the globe to clean up, fix up and conserve their environment.

Now in its 19th year, Clean Up the World, held in conjunction with the United Nations Environment Programme (UNEP), mobilizes an estimated 35 million volunteers from 130 countries annually, making it one of the largest community-based environmental campaigns in the world. The campaign brings together businesses, community groups, schools, governments and individuals in a range of activities and programs that positively improve local environments.
Since the first Clean Up the World campaign in 1993 the improvements achieved due to the efforts of millions of concerned volunteers around the world have been astounding. Examples of community-led Clean Up the World activities include:
Recycling and resource recovery
Tree planting
Education campaigns
Water reuse and conservation
Competitions
Exhibitions
Fix up projects.
You can find more details about Clean Up the World at http://www.cleanuptheworld.orgThose are some information about clean up the world and few days ago we had an email from Australia consulate to participate beach clean up 2011 in Sanur on 17 September 2011. This program was sponsored by Clean Up the World and many affiliations in Bali who care with the environment. Many of participants are from schools, community, and diving centers around Sanur.

On 17 September 2011, we were gathered in front of the Stiff Chili restaurant at Semawang to hear some opening speech from Bali government and consulate. The event were dominated with school students age 10 above and also the teachers. We also as part of Sanur community gave our contribution to this event to keep our beach clean of course 😉

All the interns, Dive Master Trainee (Cecilie, Will and Anthony), and new instructor (Jayson) under Paul Grant supervisor were joined the beach clean up that day. We got plastic bag and one glove to clean the debris in the beach. The beach clean up area covered from Hyatt Hotel Beach until Puri Santrian Beach area. We were in the middle and we decided to go to Puri Santrian way.
We found out not so many participants went to this area. They were going to another side of the beach so it was quit enough for us. We found many plastic debris, slippers, glass bottle and shards of glass. We were walking around the beach for 1 hour and came back to stiff chili to throw away the debris to the garbage truck provided. After the beach clean up, there were also some other programs for the school students such as story telling about the environment, quizzes, and BBQ. It was a beautiful thing to do to start our day. Keep our world clean for a better future!
One more thing about clean up project… We are also making :

Underwater Clean Up “Dive Against Debris”
at Sanur Channel
on 27th September 2011
9 am, meeting point : Crystal Divers, Sanur
We will provide all the dive equipments for all volunteers for this project. If you interested to dive for free with us, you can email to info@crystal-divers.com or you can come to Crystal Divers, Sanur, Bali. See you there!
