And we here that a lot, especially from an LDS who wants to sell us the latest $1000 regulator set. However, I don't here a lot about incidents involving rental regulator failures. Dive shops tend to purchase the minimum bells and whistles easiest to maintain regulators, and they service them...

Once the water stops coming out, just make sure you store it partially inflated. A little mouth wash in the rinse helps ward off bacteria and mold but I don't think most people find it is a problem either way.

I bought a computer and bcd before anything else. A regulator is the least personal of scuba items. I put it way down on my list of to buy. That being said, I did buy my own regulator so I could get the console configuration the way I like it. A dive computer is a wonderful item for a new...

I second the tight around the neck comment. If a wetsuit or hood squeezes one or both of your corodid arteries, you can black out without warning. Black out under water = 99% chance of death. If it weren't for that, you could just try it and see.

I am wondering why somebody posting in the basic scuba forum (recreational diving forum) is concerned about if a camera can be taken beyond 39 m.

I discovered the cure for seasickness today. A 15L tank instead of a 10.4 L tank. More air = more time under water = less time at the surface and on the rocking boat.

I would say 3000. The reason is that when you are healed you may get an opportunity to dive on short notice when you can't get them filled.

Point 1: I was refering to if you were off the end of the table limit. Point 2: Good point.

With gauge mode and tables, you are also using a different algorithm and if you are off the tables, you lose your backup.

The water temperature was NOT 35 F. It it is IMPOSSIBLE for fresh water to get below 39 when there is no ice present, except at the very surface, and if the air temperature was 59, the surface water temperature was definitely not 35. Also to Mr. PG 5 Degrees Celcius is not 37 Degrees...

I don't . I always plan my MOD for the hard deck. Never know when narcosis is going to kick in.

I guess the cheaper computers may be the better ones for some things. It would be impossible for me to accidentally set my computer to another mode from the one I set it to. I have to hold 2 buttons for five seconds to change anything and essential parameters like Nitrox mode and Gauge mode...

Chem lights are relatively cheap. However, I do wonder if non-toxic for humans is equivalent to non-toxic for aquatic life.

Being LOA is the worst feeling for me when I know the surface is choppy and I have to get back on the darned boat. The worst is when you have to resist throwing up over the side of a zodiac because other divers are in the water trying to get in.

I also attached my lp inflator hose to my hp SPG hose. The only drawback is that with an airtrim bcd, I would not be able to read my SPG in the event of a mask failure. However, if this happened, I would be ending the dive anyway.

If a temperature sensor is used to compensate a pressure sensor, it only needs to know the temperature of the chip, and not necessarily the exact temperature of the water. Furthermore, they would be calibrated together so any temperature reading error would be calibrated out. Dive computer...

I don't think it is accurate to call decompression models a "best guess". The models we used are all corelated with data taken from real human trials, and they are based on substantial investigation into decompression theory. While none are perfect, they are far from a "best guess".

I read somewhere that there was a debate when power inflators first came out about whether they were even safe for recreational diving.

I would have just liked, but like seems innapropriate for this post. I am glad you posted this. It is important for people to remember the chance of surviving this is exceedingly low.

Plan your dive and dive your plan. You can safely continue your dive if you meet the following conditions: You have a backup dive computer OR You planned your dives using tables on the surface AND You tracked all of your dives using tables, and are still on the table (haven't exceed any table...
