Training:
First dive, Advanced student Ed Chaffin did
his UW Navigation for Advanced Certification. We had originally planned to have
a buddy join him but Ed was the only diver to turn up on the day, so we planned
to have him lead the open water divers.
The plan for one navigation diver leading
was:
Run line out 30 meters, leave a marker, swim
back, taking in line. Have the advanced candidate lead us back to marker and
then return us to base (buoy line). Then the a/c would lead us out and back and
finally in a square pattern. Only problem was if an o/w diver ran out of air.
Enter Caroline, an unbuddied lady who Ayleen
asked if she could join us. I agreed and Ed had a buddy. Since he could then be
independent, new plan was run line out 30 meters and take it in so Ed could
count kicks and take time. I had Dave and Jamal doing exercises at base while
Ed and Caroline went to the marker where I'd left two bags. They reappeared
with one bag, perfect, the second was in case we got separated before we
completed the square, so Ed could bring it back and I'd know he'd completed the
exercise (this was the out-of-air contingency). Ed then led us on out and back
north, and on return on the square pattern. Unfortunately, we never recovered
the 2nd marker, so another piece of trash left at the bottom of the ocean. To
atone for this crime, I at least returned from the second dive with a plastic
cup, a masafi bottle, and another plastic bottle we found floating in the
ocean.
OW training:
Dave and Jamal both did mask flood and oral
bcd inflation first dive. Jamal did emergency swimming ascent (ESA) at end of
first dive. On surface both divers did cramp removals, then compass swim out to
bottle 50 meters out on surface, switched with other buddy leading swim. In
both cases, trailing diver did snorkel reg exchange. Dave did 25 meter tired
diver tow of Jamal back to boat. Both divers removed and replaced weight belts,
then bcds.
Second dive, Dave and I descended first and
dave did a 20 kick cycle compass heading underwater and returned perfectly to
bouy. We then ascended on ESA, descended again, and repeated feat for
perfection. Jamal joined us in the water at that point and we descended down
anchor line to buoy and removed and replaced face masks. Jamal then led us
south 30 cycles and back again perfectly. We swam over the reef and hovered on
the other side. Dave was perfect, Jamal less so, but well in control of his
bouyancy, so I signalled a dive and we did that till we got cold and Jamal was
at 50 bar (Dave too, staggering entries was a good idea). We then ascended and
Jamal towed Dave 25 meters, handshakes all around.
Comments:
These dives were in no way remarkable. I
don't even recall the fish except for a few grunts and gobies. As training
exercises they went very well. AB Divers are a personable lot, fun diving with
them. I just wish I could use my GPS, since I never know where I am in relation
to where I've been before.
