What an uneventful day…

Early this morning Arjen and Marie-Claire left Petra and soon after Sumayyah left for Amman, it seemed like she did not want to leave.

Sumayyah is putting on a brave face before her drive back to Amman.

That was about all the action we saw today. We did some routine work in the centre and waited for 2 customers for DSD. After having gotten the entire gear ready and waiting until after 2pm we were told that the customers will not make it after all. So we packed the gear back and retired for the day.

This gave me time to attend to the problematic dive computer.

Look at the top left corner 41 – that means that the pressure in the cylinder is 41Bar, notice that the computer is not even connected.

This is comparing the computer with an analogue gauge connected to the same 1^st stage and cylinder – look at the difference in pressure readings, 200Bar on the SPG and 232Bar on the computer.

 

Now in this picture it shows how the incident played itself out – the SPG shows that the cylinder is almost empty but the computer says that it still has 48Bar in.

Now in a real dive scenario this is still enough air to do a safety stop and safely get out the water so you will continue to breathe normal as if nothing is wrong, this is exactly what I did until I felt resistance when I took a breath. I knew the feeling as I have been trained in simulated out of air situations but was confused as I trust my equipment and it said that I still had enough air. I thought there might be something wrong with the 1^st stage or even the DV and was ready to try my Octo when I heard my Under Water Horn go off. This was an immediate indication that I was out of air as the horn needs pressure to push the pin up otherwise it will just run straight to the noisy bits. I pulled the inflator hose from the Horn to save any air that might be left in the tank while looking for divers close to me; the closest diver was about 9m from me and taking pictures. This is when I decided to do a CESA as I was only 5.5m from the surface.

Luckily I have finished my safety stop by that time as we have just done a 31m dive and I was only waiting for the other divers to take their last pictures. The situation could have ended much worse.
