I am going on vacation next year and have been looking into scuba diving.  Found out that its underwater diving that uses a breathing apparatus to breathe underwater.  Not too sure if I want to or not.
I think scuba diving is so fun! It is a magical experience.
Oh good, so you know more about it than me.  I know that you carry your own compressed air breathing gas to have free movement in the water but I'm worried about getting anxious under the water.
I got pretty anxious when I went. I felt like I was suffocating every time I went under, but after attempting it numerous times, I was able to calm down and go.
Surface-supplied diving
Surface-supplied diving is diving using equipment supplied with breathing gas using a diver's umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell. This is different from scuba diving, where the diver's breathing equipment is completely self-contained and there is no link to the surface. The primary advantages of conventional surface supplied diving are lower risk of drowning and considerably larger breathing gas supply than scuba, allowing longer working periods and safer decompression
Scuba diving
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Although the use of compressed air is common, a new mixture called enriched air (Nitrox) has been gaining popularity due to
