Hole in the Wall

[scubanatic]

Looking for any information on diving Hole in the Wall in the Jupiter area. Anyone having experience stories on this dive, I would like to hear about it. We are planning a trip on Dec 19th.

The only "hole in the wall " I know of is at Molasses Reef in Key Largo. Sorry.

[scubanatic]

OK Thanks...There is a hole in the reef somewhere around jupiter Florida. Where Goliath Groupers and large bugs hang out. Should be a fun dive!

[bobert]

Sounds good, I am curious about any other replys.

I've put some links down below.

Max depth looks to be 140'.

Hey Scubanatic, are you/we planning on using Jupiter Dive Charters?

Looks like we can fit in about 30 minutes of bottom time and still keep the dive to one hour.

I have wanted to do that dive for a while now. Most of the charters in Jupiter go out there on Friday mornings. One of these days I want to take a friday off and dive it.

Anyway the site is called "the hole in the wall" or "the cave"

Here are a couple of descriptions and dive reports

My previous posting was at +4 conservatism. This gets me out of the water 7 minutes faster.

I will probably actually want to spend the extra time hanging out and looking around....

USAF Diver once bubbled... I have wanted to do that dive for a while now. Most of the charters in Jupiter go out there on Friday mornings. One of these days I want to take a friday off and dive it.

No time like the present. Anybody know the show-time?

[Genesis]

You might want to think about doing that dive on 27% instead; I'm happier with the PO2 with that profile.....

Try this on for size...

(I set last stop to 20', as holding a 10' stop in a 3-4' sea is a real pain in the butt. 20' is much easier.)

If you prefer 80/20, then try this on for size:

For the extra six minutes I'd probably take the 50/50; if something goes wrong and I have to get out early, I will have gotten some benefit of the enriched deco gas. This is, however, pushing the amount of deco gas available in a 40; you do need to be able to deco out on remaining backgas if something goes wrong. That's a fairly long hang if you lose the deco gas though (close to a 90 minute total runtime.)

Of course if I want to do TWO dives then I might take the 80/20 instead...
