Dear Fellow Diver,
When people ask my favorite dive destination, I usually
  say "the next one." You see, I had never returned to
  the same place ... until a chance to reunite with an old
  friend took me back to Grand Cayman this February. It had
  been 30 years since I last dived here, and I was looking
  for something beyond the well-known dive experience typically
  designed for the swarms of novice and occasional
  divers who visit Cayman. So, before meeting my old pal, I
  booked into the Cobalt Coast Resort on the north shore,
  north of Seven Mile Beach, where I looked forward to diving
  the nearby north wall.  
After settling into my oceanfront one-bedroom, I
  enjoyed a jerk pork tenderloin dinner sitting by the pool,
  overlooking the sea, where the warm balmy breeze kept the
  bugs at bay. But the next morning it was blowing like
  stink. When I reported to the onsite Divetech shop at 8
  a.m., I was told there'd be no trip to the north wall.
  Instead, I was taken by van to a boat dock a few miles
  south, where I climbed on one of Divetech's two boats for
  a trip to good old reliable Seven Mile Beach.  
Once they had tied to a buoy at Little Tunnels, our
  British dive guides, Gary and Sebastian, gave us a briefing
  that lived up to Cayman's reputation for strict rules: 100
  feet for 15 minutes, up to 60 feet for another 15 minutes,
  and a five-minute safety stop. I strode off the swim step
  and joined the other six divers at the bow to descend on
  the mooring line. The coral was profuse and diverse, but
  uncolorful, even in 100-foot visibility. Water was 79oF,
  whatever the depth. With Gary leading and Sebastian trailing,
  we swam through a short tunnel and then a coral passage,
  which we negotiated in each direction.  A 20-inch
  mutton snapper resting on the sand was the largest fish I saw, with lots of black
durgons, parrots, and
basslets. At the stern
of the boat I handed up
my fins and climbed up.

During our surface
  interval, they offered
  ice water and fresh
  orange slices. About
  half the 20 tank stations
  are under the cover of
  the bridge, so we seven
  divers could spread out
  comfortably. A camera
  table in the center of
  the dive deck was used by
  the sole photographer in
  our group. Despite the boat size, it has no head.  
We then headed to the Oro Verde, more rubble than wreck. Though the depth
  was only 50 feet, they restricted us to 40 minutes. Sunk in the early '80s as an
  artificial reef, a series of storms has tumbled the Oro Verde closer to shore,
  scattering it along the way. The only penetration is into the wheelhouse. I
  swam through a window, and Sebastian guided me to an air pocket where I could
  stick my head out of the water. Fun for some, I guess. Leaving the wheelhouse,
  I spotted a small grouper under an overhang with a mouthful of cleaner wrasse,
  and then two flashy French angels accompanied me wherever I went. Their attention
  flattered me, but when Sebastian fed them orange slices, I realized they had only
been mooching a handout. 
Although I was surprised that an outfit calling itself "Divetech" would insist
  on such rigid profiles, my Oceanic computer's bar graph went to the edge of the
  green safety zone on both dives. While that's of no consequence to experienced
  divers who know that by the time they surface they'll have unlimited computer time
  left, some novices fear the "red zone." We were a mixed bag of divers, some of
  whom hadn't been in the water in more than two years. Nonetheless, they told us
  that buddy teams with computers could set their own profiles, up to the limits of
  their certifications (see sidebar, Cayman Eases Diving Restrictions). When we got
  back, I rinsed my gear and hung it on handy drying pegs outside the Divetech
  facility. Before sundown, I secured everything in a nearby locker.  
Cobalt Coast is a pleasant, secluded 18-room resort, about as close as you
  can come to a full-scale dive resort on Grand Cayman. There are no stores or
  restaurants within walking distance. I didn't rent a car so as to avoid the traffic
  jams on the drag along Seven Mile Beach, so I had arranged an all-inclusive
  meal package. My air-conditioned, one-bedroom suite had a king-size bed and a
  sitting room with a convertible sofa, refrigerator, microwave, coffee maker, direct
  dial phone, and cable TV. The less expensive "garden view" rooms overlook the
  landscaped parking lot. I had a view of the pool, an ironshore beach too treacherous
  to walk on, and a long pier. On the Cobalt Coast website, the pier looks
  like a boat dock, but the water is too shallow for anything bigger than an inflatable.
  There's a mini wall (depth about 70 fsw) some 200 yards offshore and beyond
  that a deep drop off. One can scuba or snorkel from the pier, conditions permitting.
  Divetech advertises water taxi rides to either wall but not during the
  stormy winter months. In fact, one staff member wondered aloud whether they would
ever offer the service again, due to low demand and high operating costs. 
While I was having a
  Cayman Mama cocktail at the rectangular
  open-air bar, owner Arie
  Barendrecht told me he'd built
  the resort just three years ago.
  A Dutchman with an extensive
  background in the hospitality
  industry, Arie presides over the
  resort and restaurant with old
  world charm and efficiency. The
  dinner menu included meat, fowl,
  fish, and pasta dishes. Even on
  the full meal plan, I had to pay
  a premium for pricier entrées
  (steak or lobster). Recipes were
  sophisticated for a dive resort
  (Chilean sea bass in a mango
  glaze for instance), and everything
  was cooked to perfection,
  including the rack of lamb that I
  ordered medium rare. The wine
  list included a nice mix of
  Californian and foreign vintages,
  some available by the glass.
  Lunches were mostly sandwiches or
  salads. Full breakfasts were
served starting at 7 a.m. 
On the second morning the
  wind died, but I still didn't
  get to the north wall. I had
  booked three specialty dives, to
  be conducted out of Divetech's
  main facility at Turtle Reef,
  about halfway between Cobalt
  Coast and the dive boat dock.
  Ken, a British Columbian, gave
  us three divers a brief orientation
  to the battery-powered
  Dacor Sea Sprint scooter. We
  followed him out a short dock
  and climbed down a ladder to put
  our fins on in a shallow, surgey
  cove. Then, we scootered out on
  the surface to a marker buoy,
  where we descended and turned right into a negligible current, along the mini-wall.
  The scooter carried me a little faster than I could comfortably swim. The onespeed
  accelerator had a dead-man switch, so any time I wanted to stop, all I had
  to do was lift my thumb. The unit was a half-pound negative, so I added air to my
  BC while hovering. Though I tucked my scooter under my chest, as instructed, it
  had a tendency to force my head up, and I found myself using my fins more than
  necessary to keep my head down and to steer. Twice I felt some sharp thumps in my
  chest when I let the shielded propeller get too close to my body. A little practice
  would have solved those problems, I'm sure. Turtle Reef boasted a wider
  array of fish than either of the previous dives off Seven Mile Beach. I saw lobster,
  hawksbill turtles, a barracuda in the blue, the business end of 6-foot green
moray, a smaller black and white mosaic moray, and a stingray buried in the sand.The scooter proved a good tool to increase my range, although the Sea Sprints are
  limited by a 30-40 minute battery life. It was great fun, but I prefer finning.
After lunch I traveled the same route using a Draëger Dolphin semi-closed
  circuit rebreather with 43% Nitrox (Nitrox certification isn't necessary). After a
  45-minute onshore orientation, Nat (one of the few Americans on the Divetech staff)
  led us leisurely along the mini wall. At first my Dolphin was so quiet I wondered
  if it was working, but then I got water in the loop while fidgeting with the
  uncomfortable mouthpiece. I couldn't fully purge it (the exhaust hose on the twohose
  rebreather came over my right shoulder -- opposite of open-circuit two-hose
  regulators -- so a new set of purging gyrations was required). After that my
  exhalations gurgled for the rest of the dive.
Nat had warned that I wouldn't be able to adjust my buoyancy by breathing,
  since my exhalations would stay in the breathing loop. I spent much of the dive
  fiddling with my BCD, so I didn't see as much as on the morning scooter dive. A
  large green sea turtle kept a wary distance, but I hovered and observed a scrawled
filefish grazing the wall.  Emerald-green with bright blue spots, it looked like a refugee from a George Town tattoo parlor.
At our safety stop, a blue spotted
peacock flounder broke cover to
gobble down a snack, signaling his
satisfaction by raising his showy pectoral
fin. During this 88-minute dive
I could not get any closer to the fish
than with a scooter, though experienced
rebreather users can move into
those Cocos Island hammerhead schools
without spooking them.

They offer night dives Tuesday
  and Friday, so I tacked one onto my
  pre-booked package. It turned out to
  be a dusk dive, starting about 6:15
  p.m. with a shore entry out of the
  Turtle Bay cove. Our Australian divemaster,
  Sharon, lent us backup lights,
  because Cyalumes are not allowed --
  turtles like to bite them. A large lobster stalked the sand. Brittle stars
  draped themselves on brilliant orange elephant ear sponges. In a cavern, my light
  illuminated an anemone whose tentacles shone with bright orange polyps. Moorish
  idols and shrimps I hadn't seen during the day came out to play. Sharon lit up
  several file clams that looked like small beaded purses on the outside, but glowed
  red inside. Things got crowded as seven divers jockeyed for position whenever
  Sharon pointed out a subject. I didn't see any turtles, octopi, or free swimming
  eels as advertised, but the corals and sponges blazed with far more color than in
  daylight. We finished the dive in darkness under a full moon and surfaced to the
  lights of an outdoor bar just above the cove where off-duty Divetechers were partying.
  Some divers had been able to take advantage of the windless conditions
  that day to make a boat trip to the north wall, where they reported seeing a few
  reef sharks. But all I saw was Turtle Reef.  
Divetech offers more than 30 specialty courses, plus a full range of rec and
  tech certifications. They stock 63, 80, and 100 cu.ft. tanks, and they carry a
  full line of gear for rent and purchase. Nitrox and trimix are available, and
  Turtle Reef has a full photo and video center. At either location, buddies may
  shore dive any time. Weights and tanks are included in packages, but otherwise
tanks of air are $7.50, while Nitrox 32 goes for $10 a tank. 
One of Divetech's unique features is free diving instruction. As a Northern
  California abalone diver, I'm always interested in increasing my free diving range,
  so I enrolled in the two-day advanced class. A businessman from Trinidad and I
  were Sharon's only students. Our first morning was spent on classwork from the
  IANTD manual coauthored by Divetech owner Nancy Eastbrook and two other experts.
  After demonstrating breathing exercises, Sharon supplied me with a low volume mask,
  a short basic snorkel (to reduce drag), and long, stiff-bladed, full-pocket
  Sporosub free diving fins. She put me through several in-water drills including a
  60-foot kick at a depth of l8 feet. I practiced a breathing cycle designed to
  fully ventilate my lungs without hyperventilating, as well as techniques for saving
  energy and preserving air, such as raising only one leg to begin a surface dive.
  After a couple of "recreational dives" to 30 fsw, we finished the day with a rescue
  drill in case of shallow water blackout. This phenomenon, in which free
  divers lose consciousness with no warning, is the basis of free diving's cardinal
rule: never dive alone. 
The following morning Cobalt Coast looked more like a surfing resort, with
  white-capped waves crashing over the pier. So Sharon, Chris, and I climbed on the
  boat for a trip to Big Tunnels off Seven Mile Beach. Suddenly, the scuba divers
  onboard looked silly fumbling with all that gear, when all we had to deal with
  were mask, snorkel, fins, and weights. Choppy surface conditions caused Sharon to
  do a bit of improvising. After completing a buoyancy check (free divers should be
  neutral at 33 fsw), she told us to make a dive to the 53-foot mark, a requirement
  for passing the course. This seemed bass-ackward because we still hadn't covered
  proper equalizing procedures. But both of us made the depth. Before the next
  dive, I asked Sharon's advice on ear clearing, began gently equalizing toward the
  end of my breathe-up, and then constantly all the way down. I passed the 53-foot
  mark and reached the bottom at 67 feet. On my ascent my diaphragm was wracked with spasms (free divers call this "the tugs"), but with proper buoyancy I could
kick leisurely to the surface. My dive lasted 46 seconds.
The surface was now boiling, so Sharon decided we'd finish our in-water,
  mouth-to-mouth resuscitation exercises back at the Cobalt Coast pool. The course
  ended with an open-book exam. I celebrated passing the course with a cold beer in
  the hot tub.  
I then joined my friend Pete and his family at the Christopher Columbus
  Condos on Seven Mile Beach. He arranged a couple of outings with a very laidback
  outfit called Divers Down, which has one location downtown and another out
  on Seven Mile Beach. Our Australian boat captain and divemaster Stuey first
  anchored at Round Rock Canyon, off Seven Mile Beach. In comparatively murky
  water (80-foot visibility at 75 fsw), he led us through a nice swim-through.
  Near the end of the dive I encountered a large school of horseye jacks, but otherwise
  I saw mostly small reef fish. After a 45 minute surface interval, which
  Stuey borrowed my computer to calculate, we made our second dive nearby at
  Killer Puffer Fish Reef. The title character was on the lam, but we were met by
  a 4-foot 'cuda who hung under the boat for the whole dive. Stuey sat this dive
  out, so I led the group following his directions up one spur and back down the
  other, keeping the hull or anchor line in sight at almost all times. We paused
  to watch an eagle ray soaring over the sand about 50 feet down. A photographer
  from South Carolina who's a Diver Down regular did his own thing, despite a
Cayman prohibition against solo diving. 
While these dives were disappointing, Stuey redeemed himself at Stingray
  City. I had sharply mixed feelings about this dive (see sidebar, Cayman
  Controversies). While fish-feeding dives are an artificial experience, they do
  allow us to encounter sea creatures on a more intimate basis than any other way.
  Whether by dumb luck or clever planning, Stuey got four of us in the water just
  when a huge excursion boat had left and before other boats arrived. Overweighted
  and kneeling on the sandy bottom in 12 feet of water, we had as many as 17 rays
  swooping over us. Stuey used a piece of squid to lead the rays through graceful
  maneuvers. I teased one a little too long and was chastised with a hickey on my
  left calf, but I was so enthralled by the experience I hardly noticed. A highlight
  was the presence of several juveniles, who usually shy away from contact
  with divers. It looks like another generation is learning to accept handouts.  
I also snorkled at Eden Rock in the heart of George Town, where the cruise
  ships moor. It's a real reef, topping out at 20 feet down. A barracuda worked
  the edge of the reef, which was populated by blue chromis and several yellowtail
  snappers up to 18 inches long. Using my new free diving skills, I logged some
  face time with a 4-foot tarpon that was sulking in a cut about 30 feet down. Eden
  Rock is a full dive center with parking -- a godsend in the congested heart of
  town. There's no charge to snorkel off their ladder, but for scuba divers there's
  a prohibition against "outside tanks."  
Cayman is expensive. One evening we ordered takeout sushi for six -- and
  the tab came to US$169. But Cobalt Coast and Divetech are first class operations,
with friendly, customer-oriented staffs. So I felt my money was well spent. 
Still, experienced divers will not be happy with Cayman diving if all they
  can do is dive Seven Mile Beach reefs. Winter weather - December through February
  - makes it chancy. Expect a couple bad weeks during hurricane season: July into
  November. Sign up with operations listed in the Chapbook that cater to experienced
recreational or technical divers, such as The Red Baron (www.cayman.org/redbaron or 345.945.4744); they pick up divers from Seven Mile Beach accommodations. 
Stay on the East End and dive with Ocean Frontiers (www.oceanfrontiers.com or 888-
  232-0541), where there are far fewer tourists and more pristine reefs. Consider
  Cayman Diving Lodge (800-TLC-DIVE or 345-947-7041; www.divelodge.com) as an inexpensive
  and basic alternative. And, it you sign up for the Cayman Aggressor during
  the winter time, don't be disappointed if all you do is dive Grand Cayman;
  frequently it can't make the passage to Little Cayman or Brac.
