The TDI Intro to Tech course is the perfect course for divers who have heard about technical diving and want to find out more about this exciting branch of advanced recreational diving. This course walks students through the special techniques, planning procedures and skills that set technical diving apart from traditional sport diving. It will show them how to improve their dive planning methods, in-water skills and streamline their existing gear configuration, in a non-threatening and fun learning environment. The specific skills this course will highlight are:

  • Advanced Buoyancy Control
  • 
Gas Management
  • Situational Awareness
  • Trim
  • Gear Configuration and Selection
  • Many More!

TDI’s Intro to Tech course is a useful stand-alone course for the diver who wants to become a more skilled, more proficient diver regardless of if he intends to move on to technical diving. The course may also be used as an introduction to the TDI Advanced Nitrox course and the TDI Decompression Procedures course. And finally, it is also a good refresher for certified technical divers who may want to refresh their skills or have them re-evaluated by a TDI technical instructor.

Back to Bonaire (April 2012)

Val and I joined our local dive shop on a trip to Bonaire.  This was my third visit and Val’s fourth.  We stayed with Buddy Dive again, and as usual had a great time.  Augusto and his dive staff took great care of us.

On previous trips we were there in February.  This trip was scheduled for April.  While I’m not sure how much difference that makes, it was obvious that there was more cloud cover, and it even rained once or twice.  It’s my understanding that April starts the rainy season in the Carribean.  To be fair, the rain only lasted a few minutes, and was usually at night, or early morning.  It soon passed, and the trade winds quickly dried everything off.  The only real issue was my dive gear drying on the porch.   No charge for the fresh water rinse.

This year I brought my KISS GEM rebreather.  The unit is Passive Semi-closed circuit.  Perfect for Bonaire diving.  It attaches to a standard Nitrox cylinder, and extends the gas supply by up to three times.   So, I was doing dives over 3 hours on a single tank.   I always say that the most difficult part of diving is donning / doffing gear as well as entry and exit.  This unit allows me to reduce those issues.   Normally I’d do four to 5 dives a day with total dive time of 5-6 hours.  Now I can do two dives with the same bottom time.  Given the complications of dragging camera gear along, this is a real boon.

This trip was my first time with the GEM in warm water.  Up in New Jersey, we dive drysuits year round.  Now I get to dive in 80 degree water with a new wetsuit.   I also broke down and brought my “real” camera.  I’ve had a housing for my Nikon SLR for years, but this was the first time I packed it for a Carribean trip.   What a difference!   I love my Sea&Sea 2G, but it just can not compare to an SLR.

With all the new gear, the first few dives were just to get my act straight.   It took a few mods to get my weights adjusted for proper trim.  I regretted leaving my backplate at home.   It would have made this much easier.  The new wetsuit also caused a few adjustments.  During this process I spent time on the Buddy Dive reef.  Fortunately, it’s a nice reef with some interesting fish life.

I found out from the staff that Buddy Dive has a project to seed the reef.  They are working with the Bonaire community to help cultivate the staghorn coral and acropora in the shallow areas damaged by storms.  There were several areas that were being used to study the coral’s growth.  One large staghorn cropping was just off the dock.  It was naturally seeded and was growing very well.

New KISS Rebreather Website

March 14th, 2012

KISS Rebreathers is launching some new gear, and a new web site: www.KissRebreathers.com.  The site makes it easy to find information on KISS equipment, replacement parts and accessories.  They also have media from some of the photographers and videographers that dive using KISS equipment.  Check out the site for more details, and some really stunning photos.

This time I brough the camera!

Too often, I’ve had some fantastic diving experiences but can only share them with words.  California is one of those experiences.  I have sworn to myself that I will never again dive without a camera.

Here on the east coast our shore is composed of white sandy beaches.  Great for sunbathers, but not much to look at for divers.  Other coasts have rocky shores.  On rocky shores, fish have places to hide, plants have places to take root.

The west coast enjoys these rocky shores.  Kelp anchors to the seabed, and a variety of sea life thrives in it’s shelter.  While east coast diving is all about shipwrecks, west coast divers can simply drop in the water and enjoy diving the kelp beds.

Last week I had another opportunity to dive California’s underwater forests.  On my first trip to CA, my 35 mm film camera failed me, and I came home with only memories.  My last trip, I was involved in  some intensive training, and did not bring the camera.  This time, I was taking pictures one way or another.

The reason for the trip revolved around training, again.   This time I was working on an instructor cert on the new KISS GEM pSCR.   After diving the unit for many weeks in our local quarry, I felt comfortable in it’s operation.  Now I had to teach others.  My IT set up the class that involved system operation, buildup, pool and open water.  The first portions went quickly, and we were soon discussing open water.

Point Lobos

In the Monterey area, there are many options for open water dives.  After a few discussions, the decision was on Point Lobos, a small peninsula south of Carmel.  The area is mostly state park with some fantastic vistas.  Shore entry is in a small lagoon with a facility for divers.  Upon arrival we were greeted by local divers, and quickly discussed conditions prior to their second dive.  Our entry was uneventful, and we were soon swimming through the kelp beds.  There is no comparable feeling in Northeast diving.

The next day Alan borrowed a friends boat, and we headed to the Monterey marina breakwater.  I’m sure there are better placed to dive, but on my last visit we saw many Rainbow Nudibranchs close to the breakwater.  We have no such creatures here in the Northeast, so I expressed my fascination, and desire for a picture.

While preparing the boat and gearing up, we observed a number of large red jellyfish floating near the surface.  I gathered as many photos as I could on the surface, and anticipated seeing them in the water.  After a quick boat trip and back roll entry, we headed down to find the anchor a few inches from a line Alan placed a few years earlier.  Over on the breakwater we heard the Sea Lions barking above us and the shrimp crackling in the rocks.  Between drills and sea lion fly byes, Alan helped me snap a few shots of the abundant flora and fauna.

After the class, I spent my preflight surface interval photographing the topside environment.  Seals, sea lions, pelicans, … all posing for the tourist.  It was a great trip with lots of things to learn.  If you ever have the opportunity to visit, I highly recommend getting wet.

Tribute to Yasuko

July 31st, 2011

I was going to write a description of this day, but Rob Infante did a better job than I could:

Memorial

Sunday July 31st is a day of very special import, the day we lost our beloved Yasuko.  Yesterday we returned to the site of the Arundo to pay our respects and honor her amazing spirit with a suitable memorial.  After almost a year of planning we steamed out on the Gypsy Blood, filled with friends and family.  We were blessed with optimal conditions, sunny skies and mild seas with just enough of a zephyr to keep things comfortable (I reminded everyone that it would nevertheless be honoring Yasuko’s memory if somebody had to lean over the rail.  And somebody did.)

The memorial itself is a work of art, a blue granite pyramid carved with her name, messages to her, and a lovely representation of her in her dive kit (one of my favorite pictures of her, as even through her mask you can see her eyes smiling), and even a visual pun.  The logistics involved in the process were complex, starting with the design and creation of the memorial.  Carl Bayer and Sunny Longordo spearheaded the process, and did an absolutely brilliant job of it.  Saturday night it was revealed at a party we had in Yasuko’s honor, and took pride of place.  It was important to us to place the memorial on the spot where she last was, made more difficult by the semi-broken nature of the wreck.  Lowering a 173# stone to the bottom, then transporting it to the spot was also a daunting task.  The crew of the Gypsy Blood did a fantastic job of putting us in the right area. Divers were each assigned to teams.  Everyone had a job to do, everyone’s job was essential, and everyone performed their task flawlessly.  As soon as we were tied in Stephan Francke and Shelly Liu splashed to go find the exact location for the site, and in no time at all a bottle came up to indicate they had done so.  While they did that, Joe Zimmerman, Mike Bender and Sunny Longordo helped guide the piece to the bottom, with Captain Jim belaying it down.  This was one of the more nerve-wracking parts, as a hard bounce could easily have shattered the piece, but with the teamwork of all it was gently lowered.  Dan Wright, master underwater photographer, accompanied the whole process, so we could share the underwater experience and have documentation of this unforgettable day.  Dave Oldham ran a reel, so that there was now a continuous guideline taking us from the memorial to the

final site.  The last team consisted of Sherwood Probeck, Elliot Bertoni and me, tasked with moving the stone 125 or so feet.  Before splashing I was warned that it had settled into a hole and was going to be difficult to move.  With some trepidation I lifted it from the hole, but our concerns proved baseless.  The descent team had done an ideal job of putting gas in the lift bag on the descent.  Despite the weight it was very easy to control and move, so much so that even with 15 feet of up-and-down crossing the wreck we never needed to add or subtract gas from the bag.  In less than 15 minutes we had the memorial maneuvered into place.

It was only at that moment that I was able to believe that this thing we had thought about and planned for so long had actually come to fruition, that we had managed to honor and remember Yasuko in the exact manner that we had hoped to.  I felt a huge pressure release in my chest.  Seeing the memorial in that place gave voice to my grief, and, floating with my hand on the spire of the pyramid, I was overcome with emotion.

For once I didn’t mind doing deco, as it gave me a quiet time with my thoughts.  Like an oyster with a grain of sand, we try to coat our pain, to soften it so it doesn’t cut so badly.  I don’t want that, for the pain of her loss to diminish.  I want it to be sharp, I want it to cut, because it makes her feel less gone.  That’s unrealistic, and flies in the face of human nature, but for just this day I felt it as keenly as ever, and will be forever grateful for that.

Yasuko in the surf

During the dives the children onboard splashed about and swam in the warm surface water.  I was proud of how they understood and respected the gravity of the situation, and yet still their irrepressible enthusiasm helped lighten the mood, reaffirming the good in life.  Inside, the cabin table was filled with tasty foods, including Yasuko’s beloved scallops. Laughter and good food were definitely part of how we remembered and appreciated her.

The final piece to the day involved casting flowers onto the waters over the wreck.  Wrapped in our own thoughts, with scarcely a whisper, we took turns placing them.  In the slanting light of dusk a sinuous carpet of petals slipped away on the current.
