Most instructors like to sell you the Crewpack. Yes, they may make a few bucks on it (my instructors at both DM and OWSI did not) but it does make sense for them to provide it and ensure you have the proper materials.1. thinking about getting the DM crewpack online (MUCH cheaper); I'd like to know whether it'll be of negative effect for my inst.? some may perceive it as mistrust?
You should get the Divemaster DVD, the Encyclopedia of Recreational Diving, Diving Knowledge Workbook, the Divemaster Manual and the slates. IMHO there is NO POINT in getting the Instructors Manual at this stage. Your instructor should lend you his either in paper or CD-ROM if you use a laptop. The idea is that you start to get comfortable with looking up PADI standards. Unless you are going to be doing an IDC in the next few months, hold off the IM. PADI is currently working on a major overhaul of the IM and streamlining it.2. for those who been there already; what are the EXACT contents of the crewpack? Since i'll buy it online; I need to know the exact breakdown of it, books, how many/ what slates, accessories,...etc.
Answered above!3. Are there any updates for 2009? compared to 2008 & 2007 versions?
Most materials give you a choice of answering in Metric or Imperial. Obviously the RDP is either in one or the other...I'm not sure I get the thrust of your question....4. Are there any difference in the materials between Imperial & metric versions aside from the wheel?
As stated by others the eRDP and the Wheel are OUT as of today, 01/01/09. The RDP stays ( a wise decision) and eRDPML is in.5. is the eRDP really required? does it come in metric or imperial or is it good for both?
Answered above.6. has the wheel been replaced by eRDPML for course requirements?
Same to you, enjoy the course and please feel free to come back with any more questions.thanks & happy (2009) holidays
