I usually have no problem editing a post. Today I tried to edit a new post but when I press the "edit" button the screen pops up empty (nothing to edit) even though the correct thread title is listed at the top. I closed the browser, got off Scubaboard, reopened the browser, got back on...

Is your knife sharp enough to cut anything? I've been sharpening a lot of my (non-dive) knives lately and it reminded me to check my dive knives. I only use one small one but I own several. None of them were really all that sharp until I sharpened them. How sharp are your knives? :)

Who uses their snorkel? :) Just kidding! I'm actually going snorkeling tomorrow at a local in-city lake since the weather is so nice and hot it's actually a reasonable thing to do. Not much to see I'm sure but living in the PNW and being able to snorkel without any exposure protection is a...

What have we learned since the diffused gas models were first presented to us? We know that bubble models add bubble dynamics to the discussion. Exercise and hydration has been discussed along with things that might cause on gassing and off gassing to not be at the same rate (cold dive and...

Based on another thread and thinking about this subject again I have a couple of questions for anyone who can shed some light! Haldane/Buhlmann dissolved gas theory is considered to be perfusion limited in that one tissue may be saturated and another nearby tissue may not be but unless that...

Frequently there are questions in the Dive Computer sub forum wanting to know which algorithm a particular dive computer uses but rarely does anyone ask how those algorithms actually work (beyond asking if it is "conservative or liberal"). I thought I'd attempt to explain in a generic sense...

Finally a good scuba video/program on TV. I just watched it on KIRO. Maybe it will be repeated or available online for anyone who didn't see it. It was called "Secrets in the Sound". No drama, good production quality, no messing around with the marine life and pretty complete. The only...

I have a Toyota Corolla and suddenly the clock and radio and dome lights don't work. I checked the manual and located the buss fuse that controls this. It turns out that it is in the engine compartment. I pulled that fuse and it is shorted out. I replaced it but as I was replacing it I could...

There is an excellent thread currently going on discussing OOA as a "trigger" for scuba deaths. I'm all for trying to learn from or prevent any scuba death where that's possible as I'm sure everyone else is as well. The only problem is that if you find a cause for a large percentage of scuba...

How about giving us some info regarding your favorite shark. For me it's the Pacific Bluntnose Sixgill shark. I've had 29 encounters and therefore have been able to observe it at length. It's unusual in that it has 6 gill slits (rather than the more "modern" 5 gill slits) and it has a...

We're always trying to learn something from the Accidents and Incidents reports...sometimes we do and sometimes there's not much to learn. As we know it's usually the little things that add up to make for a bad day...the commonplace things rather than large things that stand out. What are...

This is a light I came up with as an experimental test (dive) light. The first picture is of the front and the second is of the tail with a pen in the picture for size reference. They are not great pics but perhaps are adequate since you can't really tell much about what I've done from pics...

I thought I'd start a thread that anyone can add on to with their favorite easy to do DIY tips. 1). I have a tank holder in the trunk of my car that a buddy made and gave to me. It's simple and works great. It's simply 3 pieces of 1" diameter PVC pipe slightly longer than scuba tanks. Holes the...

Since there are some concerns, when diving deaths are reported, that it's inappropriate to discuss or it's unfair to the family or whatever the concerns may be what about simply editing the name out of all reports? I don't know if this is necessary and if it concerns someone from this board we...

If you're tired of reading the what's wrong with diving threads (and aren't we all ;)) here's your chance to bail out now...... Most of the issues regarding dive training and the issues involving dive shops have been discussed but I think the biggest issue is just the disconnect with reality...

New divers frist looking at equipment are frequently on a budget. I thought it might be helpful to have a thread that addresses some of the issues a new diver faces. There won't be unanimous agreement on any specific gear choices or advice but diversity of opinion is welcomed and it should at...

If a light manufacturer is being more realistic they will advertise runtimes down to 1/2 of the max lumen rating not all the way until it actually quits. It a light doesn't have a constant current driver (in which case it will be at max brightness until it just suddenly quits) it will only be...

I just got around to reading Sheck Exley's classic "Caverns Measureless To Man". I'll keep the review short because I didn't really think it was all that interesting which surprised me. I'm posting mainly because I'd be interested in hearing other's viewpoints who obviously have found this to...

I just finished reading "The Silent World" written by Jacques Cousteau and originally published in 1953. I'm sure many of you have read it but for those that haven't be sure to add this to your book list. I'm sure it was written with the non-diver in mind but I think it's even more interesting...

I've just started watching Sea Hunt for the first time. It's the first time it's been available to me. I love watching it. It's interesting from a historical perspective and a little cheesy of course as well (it's TV)! I'm curious as to how vintage divers view the program. What do you like...
