The tanks are 7.25" diameter (nominal). Don't worry, the highland bands will fit, just make sure you get the right model for your manifold. The shop should ask you brand and possibly age (esp. if its a dive rite you'll be using). I had a rec wing for about two years, then it went to ebay. There...

7ft per min was about our walking speed around the Cove 2 pier with hats over our eyes.

Roger doger. A story for you all... I remember following line around the dock area at Cove 2 for Tech1 with Andrew (walking not in the water). I think it took us 1.5 minutes with our eyes open. Then we put hats on over our eyes and had to repeat the exercise. I think Laurynn and I took 10 or 12 minu...

Can be ordered here: m Along with some others. The reason the masked diver avoided touch contact with the line to get the no-mask diver "out" (of the simulated overhead) is because touch line following takes FOREVER. Typical mask to blind times in my tech class are 1:8 You can potentially ...

There are many divers in the Tahoe area (~6500 ft) that don't do anything "special" In the no deco setting a normal ascent would be 30ft/min with 1 min stops every 10ft starting at 50% of your max depth. Working out the relative pressure changes, you'll see that sea level to 6500 ft is equ...

Its nice that wolf eels are protected from harvest - both recreational and commercial. I don't feed them either or initiate interactions. Although if one "snuggles" and plays with me I will gently reciprocate and not throw it off.

The aquarium collects fish under a scientific collection permit a means which is not applicable to individuals. Contact Jeff Kruse on this board or subscribe to the coldwater fish yahoo group to learn more about licenses and individual collecting. A painted greenling will do ok in captivity, a kelp ...

I would suggest not diving to 156ft on air/nitrox. Your judgement/abilities are probably seriously compromised as evidenced by the 5 vs. 6 ports recollection. Any little problem could overwhelm you or an increased workload can lead to CO2 retention (due to high gas density) and even more narcosis. M...

I was told about this 2nd hand by WDFW's rockfish guru. I don't remember the details but the guy had imported a bunch of lobsters and was wanting to plant them so he could start a biz. I suspect he was talking in a bar and word got around. This was supposedly ~30 years ago.

Someone tried to release lobster here once, that did not go over well with WDFW enforcement. Invasive species are one of the top threats to Puget Sound.

That's sewage, not hazardous waste. Here's the fact sheet for that treatment plant: m And here's its operating permit: m While the bacteria counts are specified to be less than 100 colonies per mL (quite clean), I don't think I would dive there. Way too many viruses to potentially come in contact wi...

PSI recommends lubing all threads with Dow Corning 111 (a high quality silicon) on all air cylinders. Cristolube on nitrox cylinders. There's no drawbacks to lubing the threads and plenty of bimetallic corrosion frustration waiting if you don't. Use a wrench to loosen, not the knob. Hand tight is fi...

I've got everything I need to CB now. Just have to plumb it all together. I trust my own gas and maintenance way more that any dive shop. I KNOW when those filters were last changed (12.78 hours ago). They have just barely started to turn the 20% RH strip and I just submitted an air sample for testi...

Heat and oil can create CO, esp. from mineral oils and continuous blending. Synthetic oils are better in high O2 or just hot environments in general. Gasoline engine exhaust is the other major source. The only thing which can remove CO is hopcalite (which actually catalytically converts it to CO2). ...
