If you want to dive on vacation, you usually have to complete a check dive on site. This also checks your buoyancy skills. Divers must always be well buoyant so that the sensitive underwater world is not damaged. The damage caused every year in local lakes and on reefs worldwide is immense! Good buoyancy control is a basic requirement for any other specialty course. It makes no sense to take an underwater photography course if you still have deficits in buoyancy control. Mastering buoyancy control naturally also contributes to safety and well-being. A well-balanced diver uses less air and can therefore extend their diving time.
