THE DAY I DIVED CCR (CLOSE CIRCUIT REBREATHER) – THE INSPIRATION
SHAH ALAM, SUNDAY 19TH NOV 2006 : Shah Alam Aquatic Center. Dept – 5 mtrs.A week ago I received a calling via YM about the CCR Inspiration try out. It was Hollowman asking me if I would like to participate in the try out. I tot to myself “open circuit” pun tak terror lagi.. somemore want to try the Inspiration??? Then again I tot.. Sifu wants to share (after so much pestering from curious friends) the experience of diving CCR. Hey.. Why not? Cuba try test lahh… bila lagi nak dapat opportunity macam nie? So.. Friends, here’s my story. In laymans terms ok.
The Brief BriefingThe girls were called up for the 1st briefing on the very basic usage of the Inspiration. My heart was already pounding.. (Thinking to myself, geez.. what am I getting myself into). The things I could remember were:
- When breathing, and if I taste the air kindda funny (stale air) abort the dive. Ask for the octopus from your buddy (at that time was Bubble Bunny) and ascend. Just in case, there may be an o’ring failure or scrubber failure that could cause this stale air to occur. (Guess what? My heart pounded faster..).
- To descend > it’s TOTALLY different! Take a deep breath thru your mouth and breathe out thru the nose into the mask nice.. and slow.
- Now there’s this BLUE button (called – the DILUENT button). When pressed, injects air. So while you inhale and experience uncomfortable breathing just press the blue button. And then breathe normally.
- And if you hear a beeping sound… ascend.
- Off course there is MORE to it, but much more technical. So this basic information is enough for our try out.
After the girls were briefed, then it’s the boys turn. I went to suit up.
The ExperienceAfter awhile I heard Sifu call for Lara.. ‘Come Lara, you are gonna go first’. What??? My eyes roaming all around fast for Snafuette. ‘Snafuette! Where the hell are you?’ Sifu said ‘Oh.. She’s underwater’ Damn! Gulp! My heart is pounding faster than ever by now. Suka tak suka.. I had to do it. I tot I cud do it second or third and watch those who started first and learn. But Sifu’s waiting now.. And the program has got to start. And I cant let down all the LaraCrofts out there can I.. heheh..
During my heart pounding moments, Sifu help strap on the Inspiration while Sheik help put on my fins.. Thanks Sheik, love u for that. Maklumlah.. tengah risau. Then I heard NazimKecik comment “Lara.. Why your face so panic?” ‘Pasal mmg panic laaa…’. Not knowing what’s gonna happen.. panic lar.
Put the mouth piece in my mouth and practise breathing first. In…. Out…. (switch off your nose now..) and In… Out… Then I felt uncomfortable.. I told Sifu, everytime I breath in, I felt that I cudnt take one full breath. Sifu told me to press the Blue Button.. and air will be injected into the ‘counter lung’ and ahhh.. now I can take a normal breath. Yeay..much better now. So in the water I go. Still breathing In…. Out.... Getting the hang of it at the surface, Bubble Bunny right there by my side and ever so patient. Its time to take a deep breath and exhale thru the nose and that will help me descend. Did that a couple of times.. and hey hey hey… I’m sinking man.. And that was a WOW for me. I did it! Once I’m down there.. Sifu skinned dive in to see if im okay. Yeah.. gave Sifu the OK sign and NOW! I gotta move from this end to the other end, so apa lagi start fining lah.
Guess what? My buoyancy sucked BIG TIME!!! One minute I’m on the floor the next minute I’m rising up. Tried to apply the breathing technique, exhaled out all the air in my lungs to stop me from rising but it’s not working. Bubble Bunny had to pull me down every now and then. Finally I just use my fins to fin down. Then I realised.. hey.. no bubbles and no sound of bubbles.. Just all calm and quiet. This is COOL Sifu! Now I’m having fun. As I reached the other end of the pool, I turn around and what do you know.. All my friends were escorting me from behind. Thanx guys.. Sheik, NazimKecik, Mocha, Holemaster, Hollowman, KatakPink, Evo, Mephisto and Comrade. By now my heart aint pounding no more.. Once awhile I could hear the sound “psst” according to Sifu that’s the sound of the (O2) being injected automatically. Cool huh? Since I didn’t get enuf of 1 round of the pool I did another 1½ round and then I hear the beeping sound and Bubble Bunny gave me the thumb up sign to ascend… sigh..
A couple of basic points I learned:1. What type of air was I inhaling in and out? Enriched Air = Nitrox
2. What’s the most basic difference diving CCR and Scuba?
Scuba = Compressed Air = dry air
CCR = Enriched Air = moist air
3. Are there any other gasses involved when diving CCR? Yeah.. Helium,Oxygen, Trimix..
If I’m wrong, please correct me Sifu. Anyway Sifu.. I will ask you questions that are playing in my head from time to time.
