PADI has designed a unique app to properly plan your dives called the Electronic Recreational Dive Planner Multi Level or eRDPml for short.


For some divers an electronic version of PADI dive tables is an easier option than trying to remember how work them. The PADI eRDPml works from an app right on your phone and can perform the many necessary functions of dive tables. Yet it also includes the ability to plan multi-level dives.


When you train to become a PADI Divemaster or a PADI Open Water Scuba Instructor you MUST know how to work all functions of the PADI eRDPml. In your exams you will have a series of questions that require the use of the PADI eRDPml.


The How To Use PADI eRDPML course is designed for every level of diver to let you:

  • Properly plan all type of dives using the PADI eRDPml
  • Avoid hours of learning on your own
  • Pass your eRDPml exam questions
  • Understand how to plan multi-level dives

Learn how to use the PADI eRDPml today!
