If you are talking Jackson blue 2 hour cave dive. Do what many people do. Conduct your dive. Throw 20 minutes O2 at it and exit the cave. See how you feel.
If its a repetative dive, or you are feeling cold. Throw 25 minutes O2 at it. If you are feeling nervious throw 30 (yawn)...
Yeah that red arrow that you saw was the farside of the shortcut jump.
Interesting that the opposing arrows are now white again. The red arrows with the tip missing are Aquatech arrows that Steve Gerrard uses to replace the original arrows. Recently when the "Line Wars" heated up again...
Interesting. It usually is marked. Did you notice it marked on the farside? I.e. the opposing arrows mark the jump to PDL, before the opposing arrows, there should be a jump marker to the left for the start of the the shortcut and about halfway between the opposing arrows and the EOL should...
After it passes through the Room of Tears it enters a series of restrictions. Then there is a point where you can jump up through a chiminey like small passage. Did you get through that area?
Dos Piso is another great dive to do. It is a shallow cave south of Tulum.
If you are guiding...
Don't do this either. Don't drop arrows at opposing arrows. Two opposing arrows are typically (though not always) used to signify the half way point between two entrances. Opposing arrows with one side being a double arrow arre used to signify the half way point between two entrances, but...
Up past Room of Tears is Dreamland. I tried getting up there once and had to turn the dive at 3rds. Its very pretty up there though also tight passages.
If your ears arn't doing so well, I would advise staying out of Naharon or the entire Naranjal system. For some reason the bacteria in...
Exploration arrows in Chan Hol are gone as of this last July. Good old Steve Gerrard has made his (negative) impact in that cave.
Tortuga/Vaca Ha/Kim Ha is indeed closed. Land was sold. New owners don't allow cave diving. Which is indeed a shame as those cave system were increadibly...
Regarding Chinese Gardens - Nope you haven't gotten there. You can't get there on a circuit. (at least not unless maybe you are diving sidemount. :) ) Its on the upstream side of Taj Mahal. Ask Danny or Fred to give you directions. Its well worth visiting.
Our dates are November 18th...
Add to that:
Chinese Gardens - Taj Mahal
Pondarosa - Chapel (stage dive)
Congrats on your class. Sucks to be doing it in a wet Drysuit though!
Take a day off and I think you will find your ears will get lots better.
Now you need to come down and dive with us in November!
It can be a sanity breath.
In an overhead envionment if you are sharing gas, the other diver is in front of you and breathing off your long hose on your right post. You are breathing off for backup on the left post which is susceptable to rolling off.
If you in a restriction you might not...
Hoods are allowed just as diving in wetsuits are allowed. Its about thermal comfort not about looking like some type of mythical DIR model.
All a hood is there for is to provide extra insulation. Its not to protect your head. If one doesn't need it, then why bring it. Plus I enjoy the...
don't be afraid to ditch the hood all together if you wish it all depends on your thermal comfort level. You can always add one later.
For cave 1 I used 200 gram thinsulate + hood. For cave 2 I used 100 gram polar fleece and no hood and was very comfortable. I have conducted up to 3 hour...
It would depend on the dive... but for the most part 35/25 would be used on dives deeper than 200'
Generally speaking 50% is usually the first bottle added, then O2 then the deeper gas.
Don't know if many other people do it, but I leave my BG drysuit inflator on my regs even when using Argon. (which I do all the time being in cold water) At depth just reach back and deploy it forward and press on it to the inflator. With the length of the hose you can keep it far awy from...
The 3' closed circuit bags are nice for calmer days which you can get in tropical waters. I have used and like the Halcyon bags. They only require a few puffs of air before they are full enough to release.
The 6' closed circuit halcyon bags are okay but one really needs to use an...
Thats seems to be the way of things for many divers. Starting the dive, you are excited, a bit nervous, potentially in unknown territory all tend to make the sac rate a bit higher. Once one gets over to deco everything tends to calm down a bit more.
We didnt have a problem with standing...
