A diver can experience difficulties on the surface as well as under the water. Therefore, it is important to consider some of the most common surface problems that a diver may have to deal with. Here are some common problems that you may encounter:
- Muscle cramps
- Choking on inhaled water
- Not establishing buoyancy
- Coughing and seasickness
With any surface problems, you should inflate the buoyancy compensation device (BCD), discard your weights, if needed, and relax. Don’t tread water or try to swim because this will exhaust you further. Wait for assistance. You can prevent or control most diving problems that may occur at the surface by first establishing positive buoyancy. On the surface, you should always establish positive buoyancy.
