Hello from John
Posted: Sat Nov 03, 2012 5:14 pm
Hello all. My name is John. I was first certified in 1975 in Lynnwood (Aquarius as I recall). Back then, steel tanks were out, aluminum was in, we didn't use computers, you just had to memorize the tables, and it was two years before NOAA started considering the use of nitrox for SCUBA. My, how things have changed.
I have 394 logged dives, my last dive in March, 1991. After what turned out to be a 21 year surface interval, my wife (Lynne) and I have decided to get back into diving. We have purchased all of our gear ($$$, my how things have changed), finished our refresher course, and have completed three pool dive sessions getting our gear situated just right. In about 3 weeks, the dry suits will arrive. I CAN'T WAIT.
If I may, a huge shout-out to the crew at Underwater Sports in Seattle. They have been doing a fantastic job informing us about what's available, what has changed, and the pros and cons of our decisions. They have been VERY patient with us as we join the 21st century and letting us use their pool to experiment with dive gear. All the while never trying to sell us on one direction or the other. KUDOS to John, Terry, and Ken.
Cheers
John
P.S.
I noticed that a 10% oxygen fill was suggested for somebody on the fourm. Got me thinking; assuming a PPO2 of 1.4 atm, that works out to an MOD of 429 feet. WOW! I suppose that with a gas mixture containing 90% nitrogen, the decompression obligations might just be a bit of a burden. <tongue firmly in cheek>
