Nice protected table area for working on equipment.  Each diver is given a
nice size cubical area under the table to store equipment and charge
batteries.  Both 110 and 220 provided.  Large rinse tank.  The crew is very
experienced in camera / video equipment handling.  The pangas have a nice
covered camera storage area.  There were two film crews on my trip shooting
Hidef with large housings.  No problem.  They know how to take care of

I was on the Undersea Hunter in 91 and the Sea Hunter in 95.  Both are
excellent boats and have great diving operations.  The sharks, rays,
dolphans, big animals, and big schools of fish are all waiting for you.  If
you haven't been to Cocos, ya'll go.  If you haven't been for awhile, ya'll

This is advanced diving in currents and surge.  You will want to dive
Nitrox for the extra bottom time and safety.  If you get cold, bring a 3 -
5 mm wetsuit.  Most of the dives were in 78F, with thermoclines down to 73
and one at 71.  A light hood won't be a bad idea to keep you warmer.  Due
to current and surge, you will need to hold on to the rocks.  Make sure to
bring a pair of gloves, I used the Deep Sea Barnacle gloves and had no

The crossings can be rough, especially the one out to Cocos.  Make sure to
take the proper precautions - patch, Bonine, shock watch - I take them all
and sometimes use them all at once.  Our crossing to Cocos was relatively
smooth and everyone was happy.  Our crossing back was almost flat.  Cocos
offers many protected bays for the boat to moor in, so you will sleep good
at night and be comfortable during the day.  We had great weather in the
middle of rainy season, so we were blessed.

The dive guides give excellent briefings.  The pangas go to different
locations, so you are diving in small groups.  The drivers are great with
quick pickups when you surface.  They give you extra safety equipment to
use prior to the first dive, including a EPIRB Personal Radio Diver
Locator.  The Hunter boats run a top notch diving operation.

The diving is done from pangas that have tank racks in the center.  You
never have to deal with your tank, except put it on and do a back roll. 
There is a ladder to climb back in the boat.  The only suggestion I would
make is to get ladders with flat steps.  I dive with full foot fins and the
round steps did not fit my unprotected feet so well, but for the divers
with booties, it is no problem.

The food was excellent.  I was very impressed with the barbeque we had one
night, and being from Texas, that is saying something.  The rooms have a
lot of storage, wall closets and under bed drawers.  The crew was always
friendly, they kept everything clean and they even did our laundry.

You can go on shore to visit the ranger stations and see the rock carvings.
 Well worth the time between dives.  You might see a wild pig as I did.

In San Jose, I stayed at the almost new Courtyard by the Marriott.  I would
highly recommend it.  Nice size, clean and quiet rooms.  Just across the
parking lot, within a few hundred feet are several international
restaurants - Costa Rica, Cuban, Peru, Brazil, Outback Steakhouse and my
favorite Hooters.  For a few dollars you can take a taxi to the downtown
area and spend hours walking among the shops or visiting the museum and
parks.  Of course you can take tours to see the many wonders of Costa Rica.
 This is a wonderful place, so don't hesitate.
