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 ® in an electronic format.
