6 weeks course meeting once a week or meeting multiple times a week?
I think it was twice a week 2 hours but I may be wrong. It certainly wasn't every day because I was working at the time. But the course had everything and we had no computers then so much of the course was learning decompression charts which you had to bring down underwater with you.
(I am not good in math and with almost zero visibility, it wasn't easy)
Besides de compression we learned beach diving, wreck diving, night diving, diving with hazardous animals, rescue diving, medical aspects of diving, zero visibility diving and of course all our dives are with a quarter inch wet suit and bulky gloves.
There was only one kind of certification unlike now. My wife and Daughter was certified 13 years after me and their course was completed with just a few hours of training.
They tell you right away that If you did all your dives in the tropics, that doesn't count as any diving experience in our courses here because in the tropics, you can see and diving with just a bathing suit and visibility is pretty easy.
Everything we carried on all dives were tethered to us. We always brought a hand spear, that we made from CB antennas, a light, knife (to cut all the fishing line you get tangled in) de compression charts, back up light and back up knife. We also normally had a 10' "buddy line" tied between us or else we dove alone because we would never find each other even 4' apart.
I dove alone many times because we don't always have someone that wants to dive here.
(I had a sea urchin collection business and I used to sell them to hobbiests for algae infestations. 😁 )
We made the line with a float in the center so it didn't get caught on the many things sunk here.
(there are 2,000 wrecks around Long Island)
We always carried a light diving here even in the daytime because deeper than about 30' it is pitch black. The light doesn't help much because it is black because of particles (detritus) in the water and not a lack of light. When you turn on your light you see a hazy tunnel about 3' ahead of you as it causes all the particles to glow like milk.
Night diving it is clearer because you don't get the haze from the sun and lobsters are out hunting at night.
There is no real swimming here, we just pull ourselves over the rocks looking for lobsters or artifacts. Once you get arms length off the bottom, you can't see it and our lobsters have huge claws which can take your arm off so you have to practice catching them.
Of course diving the tropics is much more fun and safe and I do have maybe a hundred tropical dives but I would have to find my dive log for that. 😁
This is next to a famous lighthouse here in the Long Island Sound that was commissioned by George Washington but I don't think he dove much here.
We climbed up on the rocks here one day and noticed that the front door was open. It had been boarded up for many years so we took our lights and went in. The first floor was filled with WW2 radio and radar equipment in pristine condition. We didn't want to take anything because we had to swim back to my boat so we went back the next weekend only to find the door repaired and a fence around the entire Island as it is a national landmark. We didn't get anything.
Under the spiral staircase in the light tower is a cistern where they used to keep fresh water for the light house keeper. The first floor had a kitchen and at one time, electricity.
I was hired to see if I could get the electricity back on but I found the cable from shore a couple of miles away had been cut in many places probably from anchors. They wanted over one million dollars to put in a new cable. That was probably 25 or 30 years ago and the place still doesn't have electricity.
But it has cormorants. Those birds on the top. Once I was diving there at night and those are diving birds. One crashed into me and scared me to death as it was trying to get away by flapping it's 3 1/2' wings around my head dislodging my mask and regulator. I thought it was a whale
This is on top of that light house with my main squeeze.
Alisa diving will open up so many more places in the world that you want to visit. An example is Bora Bora in French Polynesia. There is almost nothing there on land, but the diving is IMO the best in the world.
This bar is about the only thing there on land
