I recently got my advanced open water certification for scuba diving. It was awesome. I don't know anything more peaceful than diving. Focusing on breathing brings me back to myself. The colors are spectacular. The sea life is fascinating. To get my certification I had to cover five subjects from a list. I did under water navigation, under water naturalist, night diving, deep diving and wreck diving. Knowing how to use a compass will most likely come in handy. Knowing the critters and plants you will see makes you sound smarter. But my favorites were the last three. I don't know what it is about night diving that is so exciting...for me I would say it is the great-black-unknown. I am sure that would creep most people out...not knowing what is outside your vision...lurking in the darkness...praying your dive light doesn't crap out...I LOVE IT!!! Funny thing about it is that I get terrified from scary movies and horror stories. Guess you could call that a double standard.I did the deep and wreck dives together. The first one was of a Canadian destroyer called the Yukon. It was laying on its port side in 100 feet of water. The destroyer was neat in the fact that it was complete. It has only been in it's final resting space for 7 years. No much sea life growing on it yet but you could see it wouldn't take many years for it to be a habitat for starfish, crabs, anemones, urchins, sea cucumbers, and such. The second dive of that day was of the Ruby E...a Coast Guard Cutter. It was resting pretty much upright in about 75 feet of water. The difference between the two boats were staggering. The rusted metal. The sea life. The temperature of the water. Even the color of the water was different. At 100 feet the water appeared green. At 75 feet the water looked more blue. I enjoyed the Ruby E more most due to it's dilapidated state.I took footage of both dives. I kinda felt like I was the cinematographer that filmed the beginning of Titanic were they close in on the bow of the ship...and all of the plankton is floating this way and that...I could almost picture the ship, squeaky clean cruising the open sea...just imagine.
