Back in the 1981, at the ripe age of 19, a friend, Mike, and I decided to get our Open Water SCUBA certification. We stopped
in at the local dive shop, Tackle Shack, and learned what the class would
be like, how long it would take and how much it would cost and when it started. After agreeing on a start date, I signed up. Mike needed to go home and get his
check book and he would sign up the next day. That was the last that Tackle Shack saw of Mike. I finished the class have had a on-again, off-again relationship
with SCUBA ever since.
I spent years spearfishing with my Sea Hornet 48, chasing down Spiny Lobster and later using a Nikonos-V camera.
My biggest issue with the camera was that only 36 exposures fit on a roll of film. It appears that the digital era has solved this problem.
It looks like I'm entering another on-again period. I just finished my Enriched Air certification, more
commonly known as NITROX. This will allow me to use air with a elevated Oxygen (O2) level. Normal air has a 20.9% O2 level where NITROX,
at my certification level, may be up to 40% O2. This allows for safer or longer dives compared to normal air, as long as you don't go too
deep. Oxygen becomes toxic at certain depths, depending on how much Oxygen is in the gas that you are breathing. Going into convulsions
at 100+ feet down would not be a good thing, but that is why you need to be certified and they don't let just any Mike do it. I took this
class at Tackle Shack as well as a skills update course in July 2012.
Recently I had the pleasure of six dives in Hudson Grotto.
Tracee was finishing up her OW1 class and I tagged along as a refresher class. It's a good place for training and checking
out new gear but wouldn't be on my top ten vacation dives. She calls it the murky hole. The vis was about 8' and it was warm enough, at least above 40', that a wetsuit
wasn't needed. I dove this using a pair of vintage 1980s Orca Skinny Dipper dive computers with new o-rings and batteries.
They both worked perfectly although the algorithms are a bit out of date. The 'Dippers' have since been replaced with computers that can handle mixed gasses.
