I think most people have heard how spectacular Cocos Island diving is, so I
won't belabor that point except to point out it is most definitely not a
place for beginners.  Or people who don't like sharks; I lost count of the
number of sharks I saw on the first day.

I did want to give kudos to the crew of the Argo (part of the Undersea
Hunter group, and their boats share crew members).  They are the perfect
blend of friendly, skilled, fun, and professional.  The Argo itself is a
very large boat with comfortable and very spacious quarters and common
areas.  It holds a max of about 16 divers who are then split into two
groups for diving, each with its own divemaster and panga.  The groups dive
different locations so that it does not get crowded underwater.

Safety is a primary concern.  All divers are given surface sausages and
remote locator beacons to be used when necessary.  Since most dives are
deep (2-3 per day below 100 fsw), divers are encouraged to use Nitrox, and
training is available on board during the 1.5 day trip to the islands for
those who wish to get certified.  The divemasters are there when you need
help, but they do not "babysit" or get in the way of capable
divers, so you never feel that they're always looking over your shoulder.

My next trip to Cocos will definitely be on an Undersea Hunter boat.
