I think that used properly, tables backed up by a dive computer are a valuable if not essential addition to a dive. but hey, they are not for everyone.

Just the same as noone gets undeserved hits following deco on the fly - oh wait. We don't know because GUE don't release any data. Actually, I was going to write something similar to that before... It's all theory and based on a computer model. If you go back to absolute basics, they are...

If you want to take the class, take the class :) It's easier since you haven't bought any gear yet and it may make sense to go in the wing direction. Remember though that the gear dosen't make the diver - the skills do. Thats to say a wing wont immediately solve all your problems. I've...

Are you diving twin cylinders or stages? If you are diving singles, I'd put the 50 as an octo on the 100 1st stage and away you go. If doubles, use both regs - one 1st and one 2nd per post. They are great regs and you won't have any problems with freeflows providing you keep them well...

Get back to me when GUE have conducted over 10 million of these dives using their deco system and the incidents that have happened along with it (which you will never get because they are covered up) - then you may start to have some decent data. Because over 10 times this amount are conducted...

er, money? When I was first certified I asked my instructor about the class. She said it was a waste of money and that the same result can be achieved by simply putting that money towards diving and buoyancy control will come with experience. I think she was right.

I just came back from Egypt with my diverite 10w HID. The battery and can were in the checked baggage and the light head/cable/top of can were in carry-on. I didn't get pulled up once in either direction. A friend was pulled up in Rome because the battery looks like a stick of dynamite...

I follow DAN's previous recommendation of a 24 hour desat before flying (which I follow anyway - I don't take any notice of my computers no fly time). okay the exhaustion comment was for dramatic effect and redunant. The point is that you bang on about not trusting a computer (which are...

Set aside your feelings for a moment. seriously. What sort of information would you put more trust in? The first piece of information is provided in a classroom setting with no notes provided or even available. The two day course is extremely long and tiring with 12+ hour days. You are...

Sorry, you're right. I'll rephrase. I guess if JJ says it to be true, it must be right.

So if you can't verify a computer is correct, how can you verify that you are correct? I guess if you read it in a book, it must be right.

Australia is a relatively new country too - but I don't see people getting married in kilts because their great great grandfather was scottish and they have a "proud scottish heritage". When Americans do it I think it's funny more than anything else ...

Congrats Mania! My wife & I just returned from Sharm and I printed your guide before we left so she could read it. She kept asking "What does mania think about ...... ?". I personally have no interest in doing the DM course but have done AEAN and deco procedures and I'd suggest...

I initally asked beause 90% of serious divers in this country put their depth timer on their left wrist. You see, most of the population need two hands for reeling - obviously you simply hang your camera off your large head in your 5 knot current. I have both. One one left (d-timer), one on...

How do you know when you have reached your first deco stop?

I have both.. AI console and wrist mount. (and depth timer) To the people who mount their computer on their right wrist.. what do you do when you are ascending on a reel/smb? You have to hold the reel in your left hand and turn the reel with your right. You can't see the computer on your...

ah, ok. I misunderstood. I thought you were including [non-commercial and military], not excluding [commercial & military]. You know, I think I could put up a good argument about DIR, strokes, SEAL team divers and levels of training.. but in the interests of not starting a flame war ...

While I agree with the first bit, Military divers have their own procedures, gear configs and rules most of which are not DIR. ie. Military divers are strokes. (note: this is NOT a viewpoint I agree with)

Yeah, but I bet you didnt do it with knees bent at 90 degrees like the scuba "frog kick"- otherwise your feet would be out of the water, lol The way I was taught to swim breast stroke, the kick was pretty much exactly the same as a frog on the surface of the water - you bend, then extend your...

There are people on here that will say there is the only ONE true fin, all others are garbage and no matter what diving you do you MUST wear the one true fin otherwise you will die. (the one true fin being the SP Jet). These people don't consider that there are divers with different...
