Along with the section of dive equipment contained in Dive Theory eLearning, you can gain additional knowledge about equipment by studying with Equipment Specialist eLearning. Your PADI Dive Center/Resort staff or your PADI Instructor can provide additional information about dive gear that will be useful throughout your diving career.
For the RDP section, you’ll need to have both the RDP Table and eRDPML. If you don’t already have these, check with your local dive center to get advice about everything you’ll need.
