Certification and depth limitations

[Sipadan]

My PADI qualifications give me a depth limit of 30 m, I know there is some debate about diver experience and the 40 m recreational limit, but it's not clear cut and I'd hate to be arguing that one with an insurance company.

I've just completed IANTD Basic Nitrox which gives me a certification limit of 39 m. Do you think this is valid for insurance purposes, since I don't hold a specific deep qualification from any agency?

All this will become irrelevent when I finally get my Diveleader and depth progression sorted, but I'm not holding my breath and in the meantime...

BTW, I'm well aware that little plastic cards mean very little, this is about insurance policies and small print.

Cheers

Not 100% sure, but I would say that your 'IANTD Basic Nitrox' is just the max depth you could actually use Nitorx too! I dont think it actual over rules your diver training limit of 30m. I think you will find your still rated to 30m MAX.

Yet another post about depth "limits" (which are often only recommendations). Why don't you all just go and get an ANDI Full Trimix ticket, it specifically says "without depth limits" that should cover all needs.

Cert card says 'Qualified to dive to 39 m using nitrox mixtures to a maximum of 40% O2'

Just wondering how the insurance people would view this if the sh*t hit the fan and they had to pay out.

Unfortunately insurance companies don't seem to see it that way.

Nah, it'd be cheaper just to pay my own chamber fees

So will twin 12's be enough for the Titanic, or should I be looking to upgrade to twin 15's?

Well no offense but I sort of fail to understand why a nitrox course would qualify you to ~40m, since the pp of EAN32 is over 1.4 at even 35 metres and the other common mix EAN36 is over 1.4 at 30 metres....

Have a look at DAN insurance, I think you will find that it goes from ppN2 rather than your plastic qual card for depth limit.

If you want a pp02 of 1.4 at 40M use 28% nitrox, this will give you a ppN2 of 3.6 which is equivilent to diving air to 35M (ignoring narcotic effects of O2).

The whole point of doing a nitrox course is to understand the implications and effects of using EANx, you could learn to dive 32&36% without understanding the physics - perhaps you are missing that he has done IANTD not PADI EANx

that is what the course is for....you learn to use the correct mix of up to 40% to a max depth of 39m.

Because the MOD of EAN28 (using a max pp02 of 1.4) is 40m, and thats better than using air.
