Why Divers UnderGround
At Divers UnderGround©, we believe in providing our student divers with as much knowledge as possible along with the best tools. We will help you advance safely into overhead diving. Our experience will help you understand the necessity for following proper cave diving protocols and the risks involved in becoming complacent in this type of environment. We are constantly diving in new and more complex caves and systems as well as constantly involved in exploration and cave surveying projects.
Although any good Diving Instructor can easily teach Cave Diving skills as it really isn’t rocket science, the importance of the experience the instructor has in actual Cave Diving situations cannot be understated. Real stories help students understand the necessity for being proficient at Cave Diving skills and procedures. Furthermore, being aware of possible situations or scenarios brought up by the experienced cave diving instructor are priceless for anyone thinking about becoming a Cave Diver. Repeating skills over and over is great training, however, an instructor who can teach valuable lessons is one who takes these skills into the real cave diving world and actually puts them to the test. That is the only way to keep cave diving training realistic as otherwise legends and myths of killer clips and superheroes arise from scary dark holes underwater where no one else can ever reach…
Valuable Cave Diving Instructors must be actively involved in cave diving activities beyond teaching Cave Diving courses. Instructors must also be actively participating in diving activities at least one level above what they are teaching.
