Although there are some who will disagree with me,.... In a nutshell, no one should be taking inexperienced divers into a cave(rn) environment, except for cave instructors; & then in the correct ratios (usually no more than 2-3). They have been trained on how to handle most any situation that can arise, any issues that someone new to the environment can have & they know the specific risks of taking someone inexperienced into these places. They also know how to convey the specific safety concerns to those under their charge. Even then,.... it is no guarantee.........
