IDC Candidate Workbook – this book contains text for all presentations in your Instructor Course and provides additional space to take notes.If you have none of the above materials, you can opt for the BASIC OWSI Kit, which contains the above mentioned materials (Instructor Manual in paper version) along with a PADI back-pack and a CD-Rom with available Specialty Instructor Outlines.
The Complete OWSI Kit contains the above materials together with the content of the Basic OWSI Kit. To reduce the weight of your luggage, you are not required to have a personal copy of each of these books with you. If you come to do the Instructor Course with a group of friends, one copy for two or three candidates is enough.
You also need the following Specialty Outlines in an accessible format – if you have a computer, it is OK to work with the Specialty Instructor Outline on CD-Rom, if you do not have a computer with you, you need paper versions.
