Can you learn these skills in two days? Or should you have those skills and review them in the two days?The SDI Solo class SHOULD teach you some important things. My students learn a lot about multi-tasking, stress management, mitigation strategies, emergency tactics, and more.
Of course there's some things you learn on the course as you go through the lectures. There's not enough time to learn new "core" skills such as using a twinset/sidemount/backup along with the other failures that your instructor's going to cause.
Question: do you really get people on that course who've never used a Pony/stage bottle backup before? Do you get them to properly monitor the gas left as they're using it?
