The PADI Open Water Dive Manual is an easy to read and follow step-by-step text book which is designed to give the student the fastest and safest system to completing an Open Water Dive Course. Included in the Crew-Pak is PADI's eRDPML for Multi-Level Dive Planning. Get ready for Easy, Electronic Multilevel Dive Planning with the arrival of the new eRDPML. Like its predecessor, the eRDP, the eRDPML is not a Dive Computer, but an Electronic Dive Table that allows you to Plan Single Depth and Multilevel Dives. While the first generation eRDP provided the same information as the table version of the Recreational Dive Planner (RDP), the eRDPML provides similar information as The Wheel Þ in an electronic format. Everyone's favorite "blue log" is now printed in full color on non-smear recycled paper. Each course has dedicated pages: from Open Water Diver through Master Scuba Diver. Plus it includes a convenient equipment checklist.
