# Recreational Dive Planner

These practice questions are for SCUBA divers that want to practice using the PADI Recreational Dive Planner imperial tables (RDP). You will need a RDP to complete the problems.

Practice your Recreational Dive Planner skills often. The RDP practice questions are self-scoring and explanations are provided to help you gain a better understanding of how to use it.
