The shame is dive instructors selling new divers less the optimal equipment and junk they don't need. The Kool-Aid should be given to Instructors that abuse the trust of new divers. I feel like starting a new thread on dive lies told to newbies to sell gear and useless stuff.
Go easy on the slams...
I doubt many reputable dive instructors deliberately sell less than optimal equipment and junk. Some do, perhaps. But likely not the majority.
For a person who wants to do strictly recreational diving there is nothing wrong with high quality recreational equipment. For the most part it is reliable, well designed, and reasonably safe if used as intended.
The problem comes when you try take tools designed for one purpose and use them for other purposes, in environments where conditions are different and those tools become less than optimal...in certain cases dangerous.
But that's a function of using the right tool for the job, not of either tool necessarily being 'junk'.
Diving, like most things, involves a process of gaining experience and developing skills over time. If everyone began diving knowing they would eventually like to perform technical dives, then perhaps it would make sense to start every diver in what might be called a 'technical rig'.
But there are many divers who prefer to remain recreational divers, and recreational equipment will work fine for them. (Either way, if you ask any diver who has been diving for a decade or so, they will likely take you to a closet and show you all sorts of gear that they've bought, used for a while, then replaced. It sort of comes with the territory!
