The Self Reliant Diver

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.

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.

If you want to do the Self Reliant Course, then there is no better place than Crystal Divers. Take a look at the Courses Section and see what is entailed.



EFR part 2

sep 19, 2011   //   by supernova   //   Interns Blog  //  No Comments
Earlier in this blog,I was writing a little about primary care.check EFR part 1
The next day, we started the lesson a bit late because Rob needed to examine the IDC, the main reason he is here, first before taught us. And we continue to watch the video and practice the skill such as:
– CPR & Chest Compression
– Conscious/ Unconscious Chocking
– Serious Bleeding Management
– Shock Management, and
– Spinal Injury Management
Then the primary care skill was done! Rob took us to the beach to “visit” the IDC and congratulate them as well. All IDC passed the final test and they are officially INSTRUCTOR! Congratulations to MATT, EMIL, MARIE, RACHEL, EDI, CHLOE. Tonight there was a party for the new Instructor but we needed to continue the lesson first….What did we do after short refreshing?? The answer is FINAL EXAM… But its not scary, because it was open book.

The next thing Rob taught us, is about Oxygen and AED. These are only recommended primary skills but we also need to know about it also. For oxygen there were 2 ways to use it, free flow oxygen for unconscious and not free flow for conscious victim. The free flow we needed to set to be 15 liter per minute and the not free flow we just breathe in from the mask. The AED machine was really easy to use, just press on, put the pad to the place, wait until the thunder button turn on and press it. Then you will be told to check the breath and the sign of the patient. We did the oxygen and the AED when there was no electricity on Crystal Diver, it’s all dark *LOL* but we still enjoy it very much!

Beside primary care, there is second care for the victim. After we treat the ABCD’S, we were able to do the secondary assessment. We did this assessment when we knew that there is no life threat for the victim. There is 4 secondary cares:
I: INJURY ASSESSMENT: We need to check from head to toe and make sure that the victim is ok.
II: ILLNESS ASSESSMENT, use SAMPLE method to assess this. SIGN AND SYMPTOMS by asking the victim, checking the pulse, breathing, temperature, and color. Inform about ALLERGIES, MEDICATION, LAST MEAL and EVENT. You need to ask questions to make some conclusion for the illnesses.
III: BANDAGING, it’s the same thing when you treat a serious bleeding management.
IV: the last one is SLINTING FOR DISLOCATION AND FRACTURES, when there is a broken bone just use what is around you like book or pencil or anything that support the broken bone. You don’t need special things to splint when you have stuff around you.
And now its time for the final exam!!! Well it’s only about the stuff we talked about before and it is open book exam, easier than the open water exam 😛 but still some of us got it so hard to understand the English :) all of us pass the exam and we are officially EFR certified now. Thanks Rob!
We didn’t stop until this step, we needed to get the EFR instructor certified so we can teach anybody who wants to learn about this. EFR doesn’t have age limit anyway. So to make us to be the instructor, Rob gave us all the knowledge review for the EFR instructor. Who finished these knowledge reviews, was allowed to come for diving in Tulamben tomorrow! Of course all of us didn’t want to miss this… so we finished all the knowledge review until late night. Around 7 I guess we all finished the knowledge review. We needed to work hard to get anything right 😉 One thing that night, after we all finish the knowledge review, there was a girl who looks pale and wasnt strong enough to walk to her room. We all thought that Rob sent the girl to pretend about this. We helped her to go to her room and we all knew that she is really sick. We found out that she got dengue fever after that 😛
Taking Break from the classroom, theory, and practice the EFR…. DIVING TIME! We all came to crystal early morning to go to TULAMBEN. This time Jink didn’t come with us because he needed to go to the doctor the other day , so today he needed to do all the things we did yesterday. We will do 2 dives and this time Eri will be the dive guide for today. We dived in the wreck and this is the first time Rob was in there. We entered the wreck with his guide. It was 4 meters long(maybe…) Between the two dives, Rob told us a little about how to teach, his life, and EFR. Nice chatting though and full of information for our teaching practice. That was all for refreshing between the EFR courses.

After all of us finished the knowledge review, this time Rob taught us about how to teach EFR.First he showed us some slide shows about the main point in the EFR and when we teach our students we need to tell them about :
1. The Goal to do these skills
2. The value of these skills
3. The key Point/ critical steps/ how it’s done
4. The video
5. The demonstration
We can find all the answer and the teaching technique in our instructor manual. Rob also told us how to make it as simple as possible. Just let the student do it for you. Let them tell you what to do depend on the book and ask them why we do this. Beside that we need to demonstrate all the skills in front of the class! Some of us done it very well and the others still needed to learn about it again. FINAL EXAM time!!! We needed to finish this for getting the certificate :) 6 of us passed the test and WE ARE OFFICIALLY EFR INSTRUCTOR.. Sounds cool right!
