Training with Leon...
What does Peter Heseltine think now?
The Harold's Picture Page Index... where Hal sends the webmaster zillions of pics and the webmaster does not have time to make 'em pretty. Some are sideways... as an aside, they are diving a slew of modified Biomarine rental units from Peter Readey.

Training with Leon... following are pictures taken by Harold Gartner of a CCR training session conducted by Leon Scamahorn in January of 1997. Featured is the "yellow beast" CCR1000. Refurbished, owned, and "rebreathed" by Peter Heseltine, M.D.

First up... let's play caption the picture. Send your caption to the webmaster.

The tale of initial training, as told by Peter Haseltine, MD

Well, I haven't completed my training yet - it's on hiatus during DEMA and my trip to Africa. Leon was held up getting down to LA by the weather and then our weather was too windy to dive on the last day he was here. Anyway, as Leon says, I could tell you, but then I'd have to kill you.

Overall I was satisfied by the training, but remember it's *no* substitute for hours on the rig learning what Leon call "muscle-memory" This is the real value of Leon's course - teaching you to fly the rig manually in closed (you maintain the set-point, no electronics), semi-closed and open-circuit modes, "boom" scenarios and landing (surfacing) and taking off (descending). I think that the analogy of OC is to C2R what driving is to flying a light plane, is a good one. You need a lot of theory and experience servicing/maintaining your rig. (I am developing a parts and sources list) But in the end, it's the hours you spend flying it that actually hones your skills and increase your safety. I figure I need another 50 - 70 hours before I even try any dive with a serious deco obligation. Effectively that limits me to 155 fsw (the 1.2 set-point cross over) and NDL tables. I will also carry a redundant OC gas supply - probably not piped in yet.

Is it worth it? Unquestionably yes. Just as the interest was beginning to fade - two nights and 18 hours days - in the pool, in the rain, significantly task loaded (not to mention a knock-down surf entry and crawling across algaed rocks on my hands and knees), I had the most remarkable experience:

This must have been the way it was when people first dived. I put in a plea for us to ban any fishing while using C2Rs. I'd like to keep having fish swim up to me.

Yes, it's still worth it
