PADI RDP w/ Instructions Booklet

The purpose of the Recreational Dive Planner is to make all dives no decompression dives. Proper planning assures that all dives, single or repetitive, are within the no decompression limits by controlling the length of the dive, the depth of the dive, and the surface interval between dives.  Use of the Recreational Dive Planner requires having and using an accurate depth gauge, an underwater timer, a slate and pencil and the planner itself.
