Dopplers solo course report:
(it gets complicated )
Background:
I'm coming from a Northeast wreck diving culture that I have no intention of leaving, but I also want to learn the skills of accomplished cave divers. I'm finding out that transitioning in this direction can be a significant problem. My training is fairly typical for New Jersey boat diving. I am reasonably cool under very adverse conditions and can really enjoy the average inshore dive. I could easily quit there and just enjoy ocean diving, but the problem started when I got cave certified (by the skin of my teeth). 8 day marathon, can't believe that any instructor would have that much perseverance. I just met all of the requirements and earned an honest pass.
Back to the problem. I watched open-circuit divers hanging in the caves in perfect trim looking like they were born there. Not moving. That image left a huge impression on me as I don't have those skills and they really looked like they were enjoying the experience. I love caves, I want to be a real cave diver too.
How do I transition to this level of perfection in buoyancy and trim? I knew that I had lots of ground to cover. OK, its much more than lots of ground to cover, Im coming from another galaxy. Took realistic stock of what I am capable of doing next. Taking fundies with my present skills and rig would be nothing short of suicidal. I needed a sensible plan.
The plan:
Get a solo card so I can practice on my own in my local quarry. After much searching, I found Doppler's solo course and signed up. But first I needed dive rescue, no problem, found and took an excellent rescue course taught by Jim Lapenta.
Reality:
Surprise! The solo course required competence in the very skills that I ultimately desired.
Oh well, I signed, so I went for it anyway. -knew it would get ugly.
Day one:
Disaster. Im diving dual HP 100s and enough wreck diving crap on my waist to counterbalance the short tanks. Steve removes the junk and now Im head-heavy with a hard roll to the left. Add to that my large wings (way too much lift) and Ive become a perfect out of control diver. Steve tends to stay nonjudgmental about others rigs, but the ultimate idea is to get me into a standard North Florida configuration. So I tell him that I might just as well start now, and told Steve to have at it. My solo class degenerates into re-rigging me. You know the movie where the general strips the guy down to buck private. It was a lot like that
Took time off from my grunt work to watch my classmates perform a 3-party, long hose, air sharing, buoyancy control drill in a perfect delta configuration around a shot line. Thing of beauty! I want to be able to do that! But Im all over the place, cant stop moving or I turtle. Steve measures me and determines that the HP 100s are too short for me and the wing has got to go. Course over? Really should have been, but hell no, I head home to get my dual LP 72s and a more appropriate wing.
Day two:
Much better with the 72s and smaller wing, no longer head heavy, but still the annoying roll. Getting closer, but still nowhere good enough. However, I can now participate and came close to passing one or two of the required skills. The roll to the left is killing me, keeps me in constant motion. It turns out that removing all the extraneous gear lengthened one of the shoulder straps. Steve saw this and got me to re-do my harness again. Even more crap to lose
Day three:
Getting even closer, but still cant hang perfectly motionless in the water column. I now see that I always required a bit of motion or current to maintain trim. However, I am also starting to see that buoyancy and trim are moving closer, almost within my grasp. Making serious progress!
Toxed diver drill. My victim accidently (yeah, right, Frank) fell backwards off of the 25 ft student platform (where everybody elses victim landed) and did a beautifully slow, face-up death spiral complete with shaking arms and legs down through a thermocline and came to rest toxing in the silt at 59 feet. Finally something I can do! My victim endured a tremendous suit squeeze while doing this, -added just for added realism. He felt like he was made of cement when I got to him. He was in intermittent seizures, it just couldnt get more real than this. (He gets my vote for this years Academy Award.) Thanks to my recent rescue course with Jim Lapenta, I was confident with this rescue. However, there was still one surprise left waiting for me. The surprise was a sharp (10 deg. F) thermocline at about 30 feet. Very hard to control the quick buoyancy boost that the warm water layer gave me. My victim dropped the seizures at about 25 feet, I figured he would then do a panicked diver routine and go for my mask, but no, just went limp. I yo-yoed through the thermocline several times, another valuable real-world lesson. (Dumping air on rapid ascent put us back into the cold water layer and we would then drop like a rock.) However, I remained in control on this one, so I actually got a pass on this skill. Won one battle, but still lost the war.
No solo cert for me. This is a standards-based course with no guarantee of passing. I didn't pass because I didn't meet the standards. Period. Steve introduced me to an instructor who will help get my skills to where they need to be to meet Steves high standards (I will most likely go back and earn the solo cert someday just for fun). In addition, a wonderful student in my class introduced me to a local PSAI instructor who said that he would be willing to conduct "as needed" workshops to finish squaring me away with respect to my rig. We also discussed his basic approach to training trim and buoyancy, -this could really work for me.
Bottom line:
Solo was only supposed to be a cert that allowed me to practice proper buoyancy and trim on my own in a local quarry. This solo course turned out to be much bigger than expected. My rig is nearly squared away and I am already on a reasonable path to acquiring proper buoyancy skills. Much value for the dollars spent!
Steve Lewis is an amazing instructor (and quite a character). I would encourage any solo diver that isnt solo certified to take Steves course.
Best,
