I disagree from what I've learned isn't a dive buddy who agrees to go out as one taking the responsibility of being the more experienced diver and ultimately yes so to speak being the baby sitter being the teacher being the one responsible.
No. A dive buddy is not necessarily more experienced or more capable. They can be approximate equals. And no, a dive buddy doesn't necessarily take on the responsibility to be a baby sitter, teacher or 'the one responsible.'
You research the meaning of dive buddy and say ur right. If u want just someone to dive with u take a friend but u don't take on the title dive buddy if u can't handle the full position that it holds.
Unfortunately, I believe your understanding of the term is lacking, particularly in how it often works in real world situations.
When divers dive together as buddies, each is the dive buddy for the other. It's a 2-way street.
dive buddies are supposed to be what arms reach away aren't they yes they are.
And this is where real world experience (which I have some measure of, diving and buddying) trumps what you read somewhere. How close dive buddies 'should' be depends strongly on conditions, such as visibility. If you ever get certified and start diving, you'll see arms length is often not what happens.
Ur comment has no valid points just nonsense why be a dive buddy then right exactly.
No, but I imagine it seems that way to you because you lack the frame of reference that comes with diving.
What you seem to think your cousin ought to have had is not called a dive buddy, it is called a private guide or private DM (dive master, which is actually a certification level but the term is often used loosely (albeit inappropriately) for dive guide).
Relatively new divers entering situations they're unsure of that may stretch their capabilities sometimes hire a private guide who can focus on them. Such divers, if they are certified and not taking a class, are still expected to be competent divers responsible in substantial measure for themselves.
