Hi Doc. It appears that my right ear rings a bit louder than the left. At times, I can sense a clicking-like sound in my right ear. Any idea what that may be? Also, how would this type of injury be "fixed?" Thanks.

Hi. I'm wondering if anyone might have a clue as to what could cause a person's ears to ring with a high pitch constantly for (so far) about a month. I think I may have injured myself fresh water diving at about 1500 feet above sea level. I was down only for about 30 minutes lifting some...

PT, thanks for the expanded coverage. I'm still a bit unclear about why so much water was trickling in. In your explainations you describe droplets that form and that, when inhaled, cause the wet breathe phenomenon. What's happening with my regs (both primary and octo) is that as soon as I...

That makes sense. Gravity holding the diapham open a bit and hence the trickle of water <cough>. Ben: I tried switching the ventri to "-" and increasing the cracking pressure too. I also switched to and breathed from my octo (ATX 40) and had the same trickle of water. Wreck: Yep, it...

Hrmm . . . My ego is too fragile. Thanks for the warning. Hehe.

So I bought a set of Apeks regs (ATX50/40 DS4) and jumped in the pool (hehe) to test em out. I'm lying on my back on the bottom (just relaxing) and, cough, my new second stage is leaking. She breathes perfect in all other positions though (deep at the bottom of that 7' pool). Now I...

Jar, as OJ said, "I plead tha 5th!" And because I've never been drugged UNintentionally, I wouldn't know the difference. :tease: Hasta.

Sheesh Doc, what gave you the impression that I'm a teenage girl? :jester: Dan

Hi Jar and thanks for your comments/observations. I have no bite marks on mouthpiece. I probably got a headache because I may have tightened my mask too tight while adjusting on the dive down in an effort to keep it from leaking (I am prone to getting headaches if I wear a baseball cap too...

Phew! Ok, so you guys think I just didn't breathe deeply or slowly enough and as a result had too much carbon dioxide buildup; hence the headache and prolonged "kooky" feeling. Easy to fix. :D Thanks for all your help and the useful information. As I said, perhaps in the future I'll...

No Doc, I don't know my Respiratory Minute Volume or my SAC rate. Could you explain (or provide a link) how to compute these figures and why knowing this information would be useful? Note that I usually have more air left after a dive than those with whom I dive and I usually keep my breathing...

I just ordered a Cobra, but I think I'm going to cancel it and go with an analog depth, air, and compass console and wrist-mounted non-air integrated comp instead. I'm thinking that going with analog gauges and maybe the Vytec wrist unit would give me everything the Cobra has to offer and more...

Hey UP, thanks for replying, I was hoping to get your input as well. What is a "feedback loop?" I thought that perhaps the mask squeeze caused my headache, but now I'm now wondering if I would have gotten a headache if I'd not been wearing a mask. In other words, I wonder if the...

Thanks Doc! I feel fine now (morning after). I'm really not sure what brought on the increased heart rate in addition to the fact that we were really humpin it on the way down. I was using a new set of fins and the increased effort and pace probably sped up my heart a bit. My mask was...

I have a Cobra and am wondering what additional instruments I should combine with it. Do you use a dive watch, another computer on your wrist, something else, or is your Cobra (or similar) all you need? If you're using an additional instrument(s), what is your reason? Thanks a lot!

I posted this in the basic scuba discussion section, but I thought maybe people who read and answer questions in this section might have additional insight. Here's a copy of my post. Sorry for the redundancy: I finished my AOW dives today. The first dive we did was to 100 feet. The...

Which would be the better choice for single tank wet suit rec diving (not too much of a load to push around)? Graphite is supposed to have a different feel than black, which is supposed to give a more "standard" fin feel. Which did you choose and why? Thanks!

The manager of the shop says he teaches technical diving, yet he says he's never heard of ANYONE requesting a 300 bar DIN valve on an LP tank. I told him to check out this board! This is the same guy who, when I asked him what his setup is, couldn't remember his tank manufacturer or the type...

After reading all the posts on this board recommending LP 104s, I decided to look into it. My LDS (Sport Chalet) says 300 bar DIN valves are NOT available for LP tanks. They say you have to go with a 200 bar DIN valve. Is this a bunch of crap? :newbie: P.S. On this upcoming Memorial...
