Following Are a Few Dos and Don'ts Related to Scuba Diving

Those who have been on a cruise to the Caribbean or Catalina know that it is the perfect place for diving as the water there is so blue and clear. You would definitely want to try scuba diving there, even if you are not into it. In order to sign up for that, though, you have to be in a good physical shape, be an experienced swimmer, and be certified. Only if you are a qualified scuba diver would the cruise diving team let you dive - after all, danger is everywhere, including underwater.
Before you embark on that extreme experience, there are facts you need to know. Following are a few Dos and Don'ts related to scuba diving.
•    Scuba Diving Dos:
1)    The two most important requirements are the good physical shape and certification. If you lack any of those, do not risk your life.
2)    The things you need to take: mask, diving fins, weight belt, regulator and octopus, compass, dive light with backup, dive knife, air tank and backup, dive flag, spare mouthpiece, first aid kit, flare gun (do not forget the flares!).
3)    It is safer and more pleasant if you have a diving partner. Do not forget to constantly keep visual contact, and try not to kick out their mouthpiece.
4)    A third person is a must. They stay on the boat, have a mobile phone, and help when getting out of the water.
5)    If you want to bring back a souvenir, take an underwater camera with you together with underwater light and backup.
•    Scuba Diving Don'ts:
1)    Do not drink and then dive. Think about your own safety and the safety of your partner.
2)    Do not forget to tell someone where you are and when you will go back.
3)    Do not eat too much before diving; before diving wait for at least two hours after eating. Otherwise, you might get cramps or troubled breathing.
These are only some of the useful tips related to scuba diving you need to take into consideration. Always inform yourself before diving.
