Yes, book and pay for a cave course and you will get the manual free!!!
Don't get p-o'd, Thanshin. More often than not, when we see this kind of question here on SB posed by young guys your age, they are really looking for shortcuts to avoid spending the money on training. We hate to see this because too often it results in tragedy.
If you're interested in learning the "ins and outs" of diving in overhead environments like wrecks and caves, find a good instructor and get guidance from him or her. It's likely that s/he will have some suggestions for reading materials, and possibly even materials to loan you. Since you are willing to spend your money on "formation" (which in English is "training"), the instructor you choose to pay for this training will be happy to guide you in terms of providing manuals and other learning materials.
People will make bad decisions, regardless, and there's little we can do to prevent a young buck from doing something stupid if he has his mind set on it. (SB has many threads in which members actively and vainly try to talk a young guy with insufficient training out of doing a particular sort of dive).I did imagine the reason for the reply had to be either "protecting people from making bad decisions" or "protecting the secrets of the business".
None of your other interests listed have the propensity to kill you.
We are simply not obligated to facilitate the making of bad decisions by providing free access to training manuals without the actual training the manuals are designed to support.
