When I was GUE we used SADDDDD.
- S - Sequence (Who leads? Who follows? In what order? Responsibilities?)
- A - Air (What mix/mixes are we diving?)
- D - Depth (Planned, max, avg?)
- D - Duration (How long?)
- D - Deco (Planned, bailout, overstay?)
- D - Direction (What headings or navigational changes?)
- D - Distance (How far from shore, boat, entrance/exit?)
The GUE EDGE sounded too obnoxious to play well with others. After Tech 2 I was done.
Having been used to SADDDDD, we hated the EDGE. We refused to do it, but not doing it was a standards violation. I created PLANS SAVE for PSAI when I was the training director for the Americas. I wanted something that was thorough, easy to remember (the harder parts of logistics and navigation you just ADD/ADDD from the SADDDDD, and could play well with others as a sensible, agency-neutral mnemonic.
