I provide links, explanations, and examples to support my statements.
In return I get insults and my posts are quoted and intentionally changed to make it appear I said something different.
That pretty much covers it. .
I started out reading this thread, and didn't feel like I could add anything of value. Much has already been said. It became very apparent very quickly that many, many people have been offering suggestions on your equipment configurations. You've defended your choices ad infinitum, which I (to a certain extent) respect even though contemporary and collective wisdom says otherwise.
But then we come to this "DECO" thing. In this case you are plain, simply and irrefutably wrong. As has been stated, "deco" is an abbreviation, not an acronym. In the English language, abbreviations are not capitalised, but acronyms are.
You have posted a picture of a dive computer abbreviating "decompression" to "DECO". It is in all caps because everything on that computer is in all caps. I actually challenge you to find a computer or watch where they use lower case letters. Almost all watches will have buttons labelled "STOP", "START", "RESET", "MODE". Not "stop", "start". "reset", "mode".
For Oceanic, using "DECO" instead of "deco" was a design and legibility decision, not an English language decision.
Your defence of your objective error in language, and your total lack of humility when proven wrong has lost you all creditibility in my mind (and no doubt many others) on not only this, but until you can prove otherwise, every other opinion you might voice.
I will point out issue that I have with your defence of your equipment. Your stance on your equipment is a paradox. You carry all of this stuff just in case you need it. Two cutting devices, reels, spools, PLB. This is all "just in case" something goes wrong, but likely you will never need it. But then you have an equipment set up which creates a whole heap of potential "this could go wrong" situations.
In all your years of experience, you have never (or hardly ever, I assume) used your PLB.
In all your years of experience, you have never (or hardly ever, I assume) had an issue with your equipment setup.
One day you might need to use your PLB.
One day you might have an issue with your equipment.
If your equipment has been fine for all these years, why carry a PLB?
If I came across someone with your equipment or with your attitude on a boat, not only would I refuse to be buddied with you, I would sit on the other side of the boat, and make sure I'm nowhere near you in the water.
Good luck to you, may you find the humility to admit that there are facts that stand up to your opinions, and opinions that you would do well to heed and take on board.
