Sidemount Rebreather Class in Gilboa Ohio

Friday, June 20th, 2014

This was a very busy week in June.   After packing the truck with five rebreathers, ten tanks, two drysuits, one wetsuit, camping gear clothes, sleeping bag and many spare parts, I headed out to Gilboa Quarry in Ohio.    The week included two classes; one a GEM Semi-closed sidemount class, and the other a full CCR sidemount rebreather class.

On arrival, half of the gear was unpacked and setup for the next days class.    The first class was SCR using the GEM Sidekick sidemount rebreather.  Balance, trim and proper buoyancy were some of the biggest issues.  The rebreather operation was not as much a concern as proper position and weighting for the best work of breathing.  I prefer to use an aluminum 80 for diluent / bailout.  However the students were more accustom to steel tanks which required more weight to counter balance.  We tried several different side mount harness during the class.  Each had pros and cons.  By the end of the class the divers were feeling much more confident and the buoyancy and trim were dialed in.

The next morning started the CCR Sidekick class.   After classroom work and gear configuration we hit the water for more trim and buoyancy work.   After a few dives and skills we were circling the quarry and starting our decompression dives.

On the next weekend we set up all of our rebreathers side by side to allow divers to go on demo dives.  Divers tried out several different units.  Others just stopped by to ask questions.   All in all a great week of classes and diving.

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.

OW Class

OW Class

When our local shop asked if I could lend a hand with classes this spring, I had no idea what I was in for.

Lately, I’ve only been teaching technical and CCR classes.  These students usually have many dives under their belt, and are looking to take the next step beyond recreational diving by honing their skills, learning new ones and expanding their dive planning and preparation.

It was fun working with newer students that were just learning their dive skills.  Since I was assisting where needed, I had the opportunity to work with a number of classes; Open Water, Advanced, Specialties, Rescue…  Then, to top it all off, the shop had nine Diver Master Candidates this spring.

I must admit, to having a lot more fun than expected.  There are always some new students that struggle with simple skills like mask clearing and U/W gear donning.  However, they’ve never done it.  We all struggled with those skills.  Once we learned how it’s done, and had some time to practice, our fear faded.  That’s when we can relax and enjoy the adventure of diving.  This is exciting to see and be around.

Technical diving involves more complicated skills that are much more demanding.  Some of my Tech students joke that I enjoy torturing them.  Not so.  The skills are required by the standards.  Once learned and practiced they become second nature, and can get you out of a bad situation.  Again, that’s when we can really enjoy the adventure.

To all those students that kept me in the pool and up at Dutch, dive safe, practice your skills, and look me up when you need a dive buddy!  Now I’m off to go diving!

Shooting a bag while maintaining buoyancy

Shooting a bag while maintaining buoyancy

This fall in the Northeast was a bad season for blowouts and poor visibility.  Several hurricanes passed by, stirring up the surf.  Often, this can help the conditions by mixing the surface water with the cooler water below the thermocline.  Unfortunately this fall it cleared out the plankton on the surface, then just stirred up the bottom into soup.  At this point, the surface had over 50 ft of visibility, but the bottom would drop to less than 5.  That’s on the days we could make it out.

On the plus side, this gave me the opportunity to drag some students up to Dutch and finish up classes.  Once most of the drills are done, I dragged the camera along to grab a few shots.   After this fall, I needed the practice or I’d forget how to work the housing.  Also, I’m playing with a new lenses/port combination that takes some getting use to.  For what it’s worth, here are some of the photos that came out well.
