"Can't we all just get along?" - Rodney King One of the things that still surprises me about internet discussions is how quickly they can deteriorate, as if people were almost willfully misreading what other people have said, or deliberately talking right past each other. It ought to be...

As far as I'm concerned, there's nothing stupid or irrational about it, and I wouldn't even think of it as a "problem" as long as it doesn't keep you from doing what you want to do. When you're in the water, you *don't* want to be right next to a big dive boat except immediately after getting...

http://www.ssahawaii.com/Equipment/SpecialCOM.html (I don't know if those are actually the current MSRPs, but that is the only site that showed up with the MSRPs for several Suuntos when I googled it - suunto vytec msrp - and they look to be in the range that I think I have seen in my LDS.)...

And I'm still wondering how we ever got to the point where a $40 mask is considered "cheap." When you think about it, there's no reason why a truly excellent mask couldn't be made and sold for a profit at $30 - and I think they can be. The only reason the $40 mask costs $40 is that there...

I dove with a plastic backplate for a long time (although that was years ago), and never had any trouble with it. I have been looking at the DSS kydex/ss backplate recently; traveling light is one of the attractions, and the whole system appears to be very well designed and manufactured...

Currents can run at different speeds and in different directions at different depths, and for different reasons - changes in temperature or salinity (e.g., where large amounts of fresh water are entering the ocean for one example), in the topography of the bottom, and mixing of water from...

I just bought an SK7 to replace an old compass that was very similar in design to the SK6 (but was not exactly the same thing). I considered the SK6 and decided on the SK7 because it was easier to read (with my subpar near vision) and because of the tilt angle. So I traded a less obtrusive...

You have raised a very legitimate issue, but I would not worry very much about the specific question you have asked, because I don't think very many instructors actually "sell" certifications - you can fairly assume that you will earn your certification, and by the time the course is completed...

It sounds like you're getting it figured out all right, and will be fine. That little bit of water in the bottom of the mask bothers some people, but not others. It isn't hard to get rid of all of it when you have a little more experience with the mask clearing drill. But there's no rule that...

Of course they do! Do you have any idea what kind of infection or disease you can get from that salsa if you're not wearing gloves?!! Plus, it's not like the gloves cost a lot of money - you can use them for preparing meat, fish, chicken, salsa, guacamole, chilaquiles, and then cleaning up and...

That is just outstanding! Many people go through their entire lives and never have the opportunity to make such a great difference in the lives of another person, and of her family - who would have been devastated if Jessi had not done what she did. I can certainly understand your pride, and...

I still have my old Nemrod (made in Spain, I believe). I have always taken very good care of my gear, and I could probably still dive that thing but for a handful of pinhole leaks along one of the seams. I have been thinking about attempting a repair and seeing if I couldn't get some more...

Summarizing: Norm = "standard" (hence the word "normal"), and so "normoxic" is a gas with 21% oxygen, because that is the percentage of oxygen found in air. Air is normoxic; but so is any blend of gases (e.g., helium, nitrogen, and oxygen) if the oxygen is 21% of the total. Hypo =...

Well, they don't call it "new and improved" for nothing. But it's like everything else - when a horse collar was all there was, you learned to like it. They actually worked pretty well, as far as I was concerned. It helped that the "new and improved" stuff hadn't been invented yet, so you...

The article doesn't actually say it was argon; coulda been methane ...

That story was written a few days after he disappeared; his body was found the following day. I don't know if that is his wife pictured in the eBay thing, but apparently he really was the king (or whatever) of shark tooth divers. The type of diving he did could be very hazardous, because the...

Okay, I went out and bought the console module SK7 during my lunch hour, and am going to order one of them DSS bungie-mount thingies - but immediately I'm looking at the way this thing is put together, and wondering if I can pry the "guts" out of it without doing some damage to the thing. I...

So Tobin, does that mean I can buy the SK7 intended to be used in a console (as opposed to the more expensive SK7 already in a wrist mount) and install it in that bungee mount thingie? Because I was just looking at buying the wrist mount model and hoping to replace the strap with a bungee, but...

Do you know when the Seahawk was made? It looks very similar to the USD Master Knife that I got new in about 1972, but the Master Knife has molded plastic at the hilt instead of the metal - the sheath and straps appear to be identical. I've got a sharp edge on my knife, but blunted the tip a...

Well, I think we can all agree on the most important lesson learned as a result of that incident - your wife's family has learned never to listen to you again about anything having to do with the ocean. On the plus side, you have the rare distinction of actually having been bitten by one of...
