Some Basic Misconceptions
1. I can dive without any formal training.
DEAD WRONG! And your odds of winding up that way increase dramatically without formal training. Visit a certified PADI Dive Shop and ask them to explain the program to become "Open-water" Certified...it's fun and you just may learn enough to keep you alive and healthy while diving.
2. I don't need anyone else with me when I dive.
DEAD WRONG again! A dive buddy serves two purposes...someone to share your awsome dive experiences with and someone who may save your life should your equipment fail (breathing apparatus is mechanical and mechanical things do break down). NEVER DIVE ALONE.
