LowerOG, H.Castle diveplans

Could somebody please share real decoplan and gas selection for these sites? Thanks!

I usually dive LOG on a 19/35 mix which enables me to poke around on the deeper parts of the T's. For deco, I bring an AL40 of 50% and an AL40 of O2.
Deco's usually about the same as your BT if I remember correctly.

For the Castle, take a stage of 50% which you can breathe on the way out and whatever bottom mix you'd like taking into account END/desired deco etc

Hope this helps

Safe diving,

Rich

A 40-50% "travel mix" in an AL80 is good for the return leg of Peacock 3 - by the time you return to the exit your deco should be about done. If you run your plan in on your deep mix (whatever that is and reserve the travel mix for the exit).

I've never bothered with anything but air for OG and oxygen for deco - but whatever your chosen 180' depth mix for OG and Henley's deep sections. If you use Trimix for OG deep you might want to also add 50% for deco as well as O2.

A nice long OG dive 180/35 (Avg ~150') air [133 cu ft total] plus ~40 min deco on 80%.

Henley's 30-35 min in on air/backgas (Max 60'), drop travel gas + 15-30 min (Max 180' Avg 150') then 35-40 min out on 50% (Max 60' - PO2=1.41) + ~15-20 deco on O2. [150 cuft backgas + 55 cuft 50%]

I believe Ary was posting the question wanting to know how to plan a swim through.

Well? Don't be shy then

Ary, I would love to share an experience about that , but my big 'ol butt won't fit thru the hole in Hendleys.

The easy way is: Drop 50 and O2 in Orange Grove, then swim in P3 on 32% and carry 2-46cf side mount bottles of 17/40. drop your 32% before the bedding plane into the castle. jump into the sidemount tunnel and approx 75 foot jump to right, line is on right hand side. after 125 feet turn right at "T" (left goes to Crypt) after 100ft you will see "T" into goldline in Lower Orange.

Just Kiddin'.....

That would be a cool dive....except any diver with the Balls big enough to make the connection will not be able to squeeze them through the restriction or dodge all the rocks falling from the ceiling

Nah, balls must be small and perhaps sidemounted
