Which is still outside the limits of the Cavern certification, both in total penetration and in depth.

The news report is, as usual, poorly written from an accident anaylisys point of view, but it makes me wonder what was going on with the instructor... Correct me if I am wrong, but shouldn't: A) the instructor recognize the signs of a diver struggling at the surface... whether it was the...

There is another issue that I think bears discussion, my wife brought it up in a thread on ScubaBoard last week that you all may or may not have seen... We were in cave country for a week and dived some of the best known caverns. We are cavern certified, but not cave, and we know EXACTLY what...

Specifically, this is the one in Vortex:

I just hate the sound that happens when the OPV valve pops open... I know what it is mentally, that it is doing EXACTLY what it is designed to do... it just sounds like a bad thing is happening back there...

We try to go side by side whenever possible in open water, we try to stay very close together (10 feet apart or less, or half of the vis, whichever is closer... we dive in a lot of 5 foot or less vis) and we make eye contact every 30 seconds or so. Having a buddy does you no good whatever if...

Hence my putting the word decompression is quotes. Obviously, all diving is deco. I am not trying to argue that a safety stop isn't a good idea, I am just saying that preventing a fellow diver from drowning by rescuing them is a great benefit to their safety, more so than a non-required stop...

When I used to dive a Transpac (I have switched to a SS backplate) I had no problem with the tank sitting too high... since, obviously, tank height is adjustable. I am another that says get a single wing for diving singles, a double wing for diving doubles and a sidemount wing for diving...

When diving within the recreational NDL tables, there should NEVER be anything more than a moderate risk to yourself by skipping a safety stop... decompression tables are quite conservative, and LONG before you get to a "greater than moderate" risk of a DCS hit you will be "decompression diving".

One more thing I would add is, depending on how close I had gotten to my NDL on the dive, that might be it for me for the day (i.e. no more diving that day) if I blew off a safety stop after having been right up against the NDL on a dive. If I was nowhere near it? No worries.

I would too, but you understand (and I understand) what a "mild" deco obligation is... that would be, obviously, situational...

Safety stops are not "decompression" stops. Period. Therefore, you can skip them. It is best practice, when not in an emergency, to make them... but they are never required. If you need to do a decompression stop, then we get into another kettle of fish entirely. As to the second part of...

Somebody I want to dive with!

I am looking forward to diving some Novas, I have three friends who own them and they all love them for OW... although for confined spaces, they are serious line traps. I am going to borrow a set. I dive Hollis F1's and love em, personally.

I am a crasher.

You can try some Afrin nasal spray (it's generic equivalent is the same stuff at 1/3 of the price). But Rollerboi is right, time is the thing you need. It will get better.

Good advice, I would highly recommend taking the camera alone outside and take a bunch of pictures, which will let you learn where all the buttons are... then, put it in the case (take the strobe off) and shoot land pictures with it outside on land... to further familiarize yourself with where...

The DC1200 the OP is buying doesn't save pictures in RAW format, unfortunately...

True, but the PADI Digital 1 class doesn't use flashes. At all. It is strictly ambient light.
