Guardian, welcome to the Board, and don't take offense at our attempts at humor. Every piece of diving equipment has been fought over here, endlessly. Humor, has taken the place of some of the rancor. As a beginning diver, you really have the world to look at. Equipment for a warm water tropical beach, is different than what TS&M needs in the Pacific Northwest. That's why many have asked, where you will be diving.
How much experience you have, determines what we will recommend. . . like a diving computer is not needed in your beginning dives, because you should not be making decompression dives until you have a lot more experience. . .
Also, related to experience, a BP&W, is necessary for many advanced divers, pushing the edges of long times, and deep depths. But the majority of divers are diving in warm waters, shallow depths, and will never dive multiple tanks. The majority of divers will never dive a BP&W, and cannot even rent them in tropical areas. Jackets and back inflates are good beginners choices for comfort and fit.
You can use the search function, to study the thousands of posts on any one piece of gear. . . but because you have had a couple of this boards messengers already post here, click on the posts of "TS&M," "the Kracken",, and "RoatanMan" These are some of the great divers on this board, and they differ in their advice, because they dive in different parts of the world, with different goals in diving.
Remember many times on the board someone will try to inject humor. . . it doesn't always come out right. The issue of snorkel. . . most instructors say to wear one at ALL times, as a beginner you may wind up far from shore, and snorkel makes a long swim more comfortable, and safer. I carry a folding snorkel in a vest pocket, when I dive a strange area. A folding snorkel, will bring out lots of comment, but after 30+ years of diving, I do things the way I'm comfortable.
