EXPLORATION&CONSERVATION

We are highly motivated in knowing more about caves, how far they extend, where they are going, how complex they become. Many times landowners would like to know more about what is laying beyond their land or what kind of fresh water resource they have. As cave instructors we need higher cave diving skills to be better educators and cave exploration challenges us to reach this goal.
