UNDERWATER PHOTOGRAPHY EQUIPMENT SAVES LIFE
Reply Quote

This incident happened last August in Sangalaki but I think I should share this experience hoping that it must just save your life too.

 

On my 3rd dive on the 1st diving day in Sangalaki, my wife and I were swept away from the reef due to strong current and we had to abandon the dive after 30mins. My dive computer went bizarre again and showed 5 mins deco time for a 30 mins dive with maximum depth of 15 metres, most of the time we were at 10 metres!!! I did the 5 mins deco stop to clear the computer (so that it would lock me out for 38 hours) and by the time we surfaced, we were about 300 metres away from the boat. We couldn’t fin back to the boat due to strong current and the boatmen were probably lying down resting as we couldn’t see them on the boat. I really do not expect them to be on the alert for the entire duration of our dive. Anyway, we ended our dive pre-maturely.

 

My wife and I were slowly but surely being swept away from the island while we waited for the other divers to finish the dive. The boat and the island were becoming smaller and smaller every minute we waited. After 20 minutes, the boat started to pick up the divers. After another 10 minutes, I can see that they were starting to look for us. (Actually, after we were rescued, we were told that they were playing and snorkeling with mantas on the surface thinking that we were still enjoying our dive).

 

Unfortunately, I left my surface marker in the room, but I don’t think they could see the surface marker even if I had brought it along. This is because by this time, the boat is really too far and the swell is huge. From where we were, the boat is less than 1 cm in size and it is still getting smaller, I could only see it when the swell brought us up. From time to time, we made desperate attempts of fining back to the island and waving frantically but to no avails. The current were really too strong. I realized that I was also fining the whole time to keep myself up because I was using a really crappy one that doesn’t have enough lift. My wife and I then decided to ditch all our weights.

 

The boat then went the opposite direction to look for us!!! At one time, the boat was only a dot in my vision! By this time the sun is already setting, it might be a good thing because they will be able to see my torch light! However, we might be swept too far away by night fall! Luckily, I always dive with at least one camera these days. I was diving with my Nikonos V and a Sea and Sea YS-120 strobe (Thank god, there is a test switch on the YS-120). I fired the strobe on test mode, after about 5 mins of firing the strobe, we saw the boat heading for our direction and we were finally picked up after over 100mins on the surface!!! What a relief but felt really bad to make all the divers on the boat really worried.

 

This is a really frightening experience because we were really being swept away from the island out to the open sea, I was really afraid for the first time in my life. I could also see it in my wife’s eye. Luckily, we were both calm during the ordeal.

 

I bought my wife a new jacket BCD before this trip and only realized that it comes with a whistle after we were picked up, we could have used that immediately after we surfaced.  The good thing is I got a Halcyon Ecilpse BCD for my Birthday!

 

Lessons learned:

1)      Always dive with a torch light, surface marker and whistle. A Underwater photography strobe can be helpful as well

2)      Use a BCD that can help you float on the surface, not just for a short time while waiting for the boat to pick you up

3)      Know your equipment well even if it is brand new.

Glad to hear that you and your wife are ok. Just some things I'd like to share:

- The other primary purpose of the BCD is to help you float on the surface. Irregardless of duration and surface condition. 

- Ideally gears should be able to be tested before purchase. Of course its impossible in most cases. But nonetheless, they should be tested and familarised in a pool setting before use in open water

Getting caught in current is just about a problematic thing most divers fear. But here's somethings that could help.

- RELAX, struggling never solves anything

- Should you need to abandon a dive prematurely, deploy an SMB (sausage) as you ascend. This give ample time for the boat to spot your position and take reference should you start to drift. It pays to tug the line once a while to dance the SMB to attaract attention.

- If you do not have an SMB take off one of your fins and put it above your head. This increases your profile above water. If you have one of those bright fins thats a plus point. It'll help to have your buddy hold on to your BCD as not to drift away from one another.

Your experience reminded me of a almost similar incident in the Riau Islands a couple of years back...

It was the last dive of the day, sky was getting dark , but we jumped in anyway...we entered the water infront of a small island.

15mins into the dive, my buddy & I were carried off by a strong current. We were in less than 15m depth than; it was like being held down in a layer of fast moving cold water...Fortuntately for us, our DM was nearby. Before we knew it, he signalled us to hold on to him, one on either side.

We had the most exciting 'drift diving' experience ever....

I cannot recall how long we drifted together, but the view of the marine live below us was flying past like the window view from a speeding car.....We trusted his decision & we let the current carried us along.

By the time we felt we could fin out of the current, we ascended.

Initially we were not sure where we were, cos we could not see our boat , and the island look so different. After our DM checked our bearing & direction, we realised we were at the back of the little island. The current had carried us along the flank & threw us to the otherside of the island, into the open unsheltered seas, where the current desipated. And it was getting darker...

There we were floating in our BCDs, our DM still holding on to his inflated SMB, my buddy & I stayed calm & relaxed. Then our DM sounded his 'quacker' above sea-level.What was already a nuisence underwater, it sounded like an air-horm above water. Loud & piercing !! 

After a few attempts & sometime later, we finally saw a our boat appearing from the eadge of the island. They too were looking for us & they heard the 'quacker'...

That experience left a deep impression in us...Lesson learned:

  • Stay calm & relax. Don't panic
  • Once afloat, think what to do next.
  • Carry some signalling device to attract attention.

Ever since then, I always carry simple whistle with me...

It came in handy last mth when we were swept out of a lagoon in Perhentian. I blew the whistle to alarm the boatman to come pick us up...
