Do’s and don’ts.

• Do use lots of fresh water and a big bucket.
• Do rinse the inside of everything with fresh water.
• Do take your knives and scissors out and rinse and dry them so they don’t turn into rusty lumps.
• Don’t forget to put the dust cover on tight on the regulator first stage before soaking.
• Don’t purge the second stages.
• Don’t press the power inflator button on your BCD. But do press the exhaust button to fill with fresh water and rinse inside the bladder.
• Do also open the bottom dump valve on the BCD and  let fresh water go out through it. Similarly you can rinse the inside of SMBs.

Legal disclaimer is here. Well actually that is for bigwall climbing but I take no responsibility for your gear or safety. That is entirely your responsibility as it was before you read this and it will always be. Dive safely!

On the way back from a really nice day of diving at Qaruh with Marja we stopped as a pod of dolphins swam up to the boat. They probably came up to check out the engine noise as they came right next to the boat they swam away a bit. One of the guys jumped in the water but wasn’t able to get to them. Here are some photos.

Technical SCUBA Diving Equipment for Advanced, Wreck and Cave Diving: Dive Rite, Inc. – Dive Rite » Dual Bladder Wings

I can’t help but remember one of Billy Dean’s talks on equipment management. He called it the triangle of influence (TOI), starting at the neck draw a triangle from shoulder to shoulder down to just above the navel. In this area should only be items needed for life support, primary and secondary regulators and BC inflation. Everything else should fall outside this area so it doesn’t interfere with survival needs.

We went on a full day trip to dive the wreck near Qaruh Island. I found out that Qaruh (pronounced garou) is named for the oil seeps that are near the island. With so much oil and gas in the ground the island got this name as in Kuwaiti Arabic gar is the word for tar.

So anyhow, the diving day began as all others, with the tanks and diving gear in baskets on trolleys getting pushed to the boat. The dive gear is normally carried in square plastic laundry baskets as the size is ideal and the baskets fit under the seats on the boat.

We walk beside the trolleys that are being pushed by the Indian workers to make sure nothing falls off. Well, the trolley with my basket was not being watched closely enough by someone else and my basket fell off into the water.

Fortunately, as I was warned some time back to make sure to fasten the bungee cords that we cross over the top of the basket through the heel strap of the fins. That way, if it does fall the fins don’t fall out and everything stays in the basket. This was advised by someone who dove in the disgusting muck of the dock to get a fin that sank. (Not all fins sink, mine do.) So, everything stayed in the basket and we managed to grab it before it sunk. So all was well.

Then off on the 90 minute boat trip Qaruh. It is a boat that was sunk by a helicopter in the First Gulf War. It is a challenging dive. And can be a challenge to find. But that is good, otherwise there would be too many people going to it and damaging some of the pristine and unique corals developing on it.

I was leading a couple of other divers on their deep dive specialty. As part of this specialty it is important for the divers to do an exercise to show them how their judgment can be impaired and reactions delayed at depth due to nitrogen narcosis.

So the plan was to give them a simulated out of air situation by me.

So here’s how it went.

Well, the visibility wasn’t great and I was with the two of them and we were circling the upper portion of the wreck. Then we got separated as there were some other buddy teams on the wreck and I mistook them for the two I was with. So when I saw it wasn’t the right two, I circled back around to the top of the conning tower and waited for them to return.

When they appeared and then I remembered, time for the drill.

So I went up to one of them and gave one of them the out of air signal from about half a meter away.

And he just looked at me with the signal “I don’t know” (In other words “huh?“.) This is an example of impaired judgment due to the narcosis and also the challenging dive conditions.

So I gave the signal harder. By then the other guy who was about a meter away and slightly below quickly swam up to me and offered his spare regulator which I took. Then he gave me the OK signal.

And he made good eye contact and gave the signal to ascend.

All very good in accordance with training and proper practices. Then I gave him the OK signal and showed him my pressure gauge that I had plenty of air so we don’t need to ascend. Then he understood, it was a drill. Needless to say, we’ve had a lot of laughs about this.

But wait there’s more
