Hey guys,
I'm not really DIR, but diving sometimes with GUE members and instructors I've been diving with went through some of the GUE courses.
However, it caught my attention that the signals they use don't seem to be what I thought was the standard. For instance when signalling a tank pressure, I'd do "1 - 5 - 0" and confirm with an okay signal, meaning 150 bars. What they would do is "100 - 5".
A quick explanation of the signs, so that everybody is clear on that.
1 = 1 finger up
5 = 5 fingers up
0 = just like "okay" but with all fingers making the "circle", an okay being with open fingers.
100 = 1 finger down
When I asked about it (it was during a course not related to DIR) I just got the answer "it comes from cave diving that's how it is.", which I'm not really happy with... Being the kind of guy that will very often question what he's being taught, most instructors seem to have an issue with me
I have been explained that the reference book for communication was the CDS-NSS "Cave diving communication" book. JJ's "Fundamentals of better diving" doesn't seem to agree with the former, for instance giving numbers going from 1 to 10 while CDS-NSS gives 0 to 9. I can't seem to find how to signal for "bigger" numbers in any of those, so having only the 0-9 range available "my" method seems to be the only one possible. Using the 1-10 range, I'm left without a clue of how I'd signal something as stupid as "12".
However, those 100 signals seem very non-DIR to me, in fact non-technical in any way as you'd still have to add 100 + 50 and take a wild guess that the guy is signaling 150 and not 105.
When asking this question on a mainly recreational forum I had as answer "well discuss it in the freaking briefing you idiot". To me, this is something that is so obviously standardized that there should be no discussion about it.
So here come the questions:
- does GUE use another communication than the CDS-NSS ? Isn't that book the reference for communication in technical divers?
- does the briefing among DIR divers cover all signals every time? If it does, then the whole DIR philosophy becomes really laughable imho. I just can't imagine it.
Thanks for any replies... To be honest, I haven't read through the whole fundamentals book, and I'm aware that the CDS-NSS only suggests this as a base set.
