Ice Diver, level 1 (W_ICEL1)
Ice diving falls under the category of 'penetration diving'. Penetration diving does not allow direct ascents to the surface, but there is usually only one or two exits where the diver can safely return to the surface. This requires extra preparations and safety rules.
During the WOSD specialty course 'Ice Diver, level 1' you will learn how to safely make an ice dive through a hole in the ice.
