Submarine after diving

[Finatik]

This might be a strange question but......I'm going to Hawaii and will be diving Molokini. My son wants to go on a submarine ride while were there. The description says that it goes down to 130'. I was planning on doing this the day after my dive was scheduled. After reading some of the posts here I'm not sure if this is such a good idea (I imagine the sub will be pressurized if its that deep).

What are your thoughts on this? Should this be considered like flying?

The sub keeps a constant 1 ata atmosphere. I don't remember any pressure change / equalization during ascent or descent. It's OK to do the sub immediately after diving.

The problem with airplanes is that they are only partially pressurized --- to a little less than 8,000' altitude. It's that reduced pressure that is a problem after diving.

BTW, I preferred the semi-submersible "ReefDancer" (deep draft boat with windows along the sides) over the Atlantis sub. If you want to show your son what your diving is like, the semi-sub is better --- it goes to a shallow reef just north of the Lahaina harbor. The true submarine is deeper, but darker and nowhere near as much sealife.

Thanks for the reply.

The only reason I was going with the Atlantis is its a package deal with the luau. Everytime I go to the islands my wife drags me to one of these stupid things. Bad food and now no alcohole comsumption...what's the point.

She keeps saying it's for the kid but I think she just like to look at ripped semi-clad guys with great tans. LoL.

I think you'll be safe also.

However, take your dive computer with you just for the heck of it and see if it measures anything. If they pressurize the sub any, then your computer should
register it I would think.

(The reason I think it will is because of the people who take their dive computers
in the test hyberbaric chamber at DAN)

Call DAN I am sure that can tell if the submarine ride will be OK.

A submarine is a 1ATA environment. No different than walking down the beach. You'll be fine.

Call DAN I am sure that can tell if the submarine ride will be OK.

How do I reach DAN? I would like to purchase insurance also. Can you give me a link?

The manual for my computer says to not pressurize it dry.

Lots of computers have water contacts too so wont turn on unless theyre shorted. Thats why people take a bucket of water into a chamber dive.
