Henley's Castle

Did a dive on 21/30 to Henley's Castle. There was virtually no flow but some say it is syphoning. This was my first Trimix dive and I found it interesting to actually enjoy The Castle. Run time was 87 min Vis 30-40 ft.
They say it was better last week but still it was really cool.

That's a LOT of helium for a 170' - 180' dive. A 21/25 mix would've more than sufficed. It's also cheaper in cost and quicker to mix, especially if you're getting your Trimix fills at "Cave Excursions East".

The more helium the better, why are you questioning a man about his mix when it is on the side of safety. an end of 100ft is the deepest I want to have.

And on top of what Caver95 said, it's not easier to mix.

21/30 works for me...but I'm a self proclaimed nitrogen whimp.

muzz:

It's easier for CEE because they already have 10/50 and EANx 32 pre-mixed in their banks. It's just a matter of filling half with 10/50 and half with EANx 32 to create a 21/25 mix.

mmcauliffe:

I prefer more oxygen and less helium and prefer to do a 150' - 180' profile with a 23/12 mix, but I use a 21/25 mix because that's what's available to me to use.

Ya that is easy, I use another method. I put the he in first then top off with 32%. It works with 18/40, 15/55 and 10/50%. I'm suprise CE doesn't use that method since they bank so much 32.

Real men dive that just on air.

John:

Up until 1996 when I got IANTD Trimix-certified, I was diving every where(Eagles Nest, Ward Sink, Arch Sink, 40 Fathom Grotto, etc.) on Air. I was doing so much of it that I had a pretty good narcosis tolerance below 200'. Those days are long gone. I'm older and smarter now. Any dive below 160' - 180', I get off Nitrox and use Trimix.
