I guess ice diving is perhaps a bit fringe?? But the way I see it is that this course could just cover the "generic" mechanics of line use, then in Wreck 1, Cave 1 (and Ice 1?) you then start applying the motor skills in the context of the specific environment.
Pretty much.
First we did dry drills, both with sight and blind, including (at least): primary and secondary ties, placements, ties, end ties, lost line, lost buddy, broken line, team formation, blind communication, gas sharing, tie navigation, jumping the line, etc.. We then did all of the above in shallow open water using blacked-out masks to zero the viz.
We also discussed gas management, with particular emphasis on open water wrecks given the immediate training goal (thirds less rock bottom computed immediately prior to penetration), environmental concerns, etc. etc..
Will experience the actual environment this weekend (Wreck 1).
