Surface supplied air (SSA) as a means of diving is one of the oldest methods of diving. Centuries ago, men operating hand pumps supplied air to divers working underwater. The deep sea diver with hoses for air and communication is known to anyone that watches WWII movies with the Navy being featured. In 1904, the US Navy adopted a hard hat deep diving suit that they used until the late 1980s.  In the late 1960s, a system was designed that brought surface supplied air to recreational user. Called hookah, The primary target was boat owners. The could use these systems to quickly go overboard to examine the hull or clear a fouled prop. The systems were a bit unstable when used in the water so they remained in just a small market for boat owners.

Diving has gotten away from the stereotype based on the early days of diving, that it is a rough and tough sport requiring extreme endurance and strength. Today it is viewed as an activity done by both men and women and even children. While diving is promoted as a leisure sport, it is still a sport.

Live aboard dive vacations can lead you to the best diving of your life. The boat will take you to dive sites that are less visited than sites you can reach on a six pack. Preparing for a live aboard is not much different that preparing for any other dive vacation. There are two main differences. You cannot just drop into the dive shop or 7-11 to pick up anything you forgot or need. Also everything is centered on diving, there are few off gas activities. No sightseeing, no discos, just diving.

Many new divers anxious to get their first dive kit will look at buying used equipment. Even experienced divers will sometimes look for replacement or additional equipment. Locating used dive equipment can sometimes be a challenge in itself. If you are a member of a dive club, let it be known that you are looking. Rental shops generally are not a good source of used equipment, rental gear seems to be abused more often than personally owned gear.

In the early days of Scuba diving when Television and movies were still portraying scuba diving as a dangerous activity (and they were right at the time) we often saw divers using underwater propulsion vehicles. The Sea Hunt television program showed Lloyd Bridges zipping around coral reefs being towed by a dive scooter. In a couple of movies, James Bond used similar underwater scooters as well as wet subs. Some were even armed. Of course any time James went underwater frogman attacked him with spear guns.
