Buoyancy control is one of the most important skills you will have to master as a Scuba diver. On the surface while entering the water you do not want to be too heavy that you will sink while on completing your dive you have to maintain proper buoyancy control so as not to surface prematurely
1. Dive within your limitations. 2. Relax while you dive. 3. Have positive buoyancy at the surface.

There are many definitions of surface diving. The most common is to go from the surface and dive to the bottom. Some people think it is different.
