Here are some of the problems I've encountered with these regs.
Cyclon 300 and Odin first stages - no design problems at all BUT,
if you have the first stages with metric threads (as we do in New Zealand) and
some mongrel has inserted a US gauge or low pressure hose without the
adaptor nipple the body treads will be weakened and possibly destroyed.
The maintainence problems I encounter are all with the second stages.
Cyclon 300:
The piston seizes in the holder if the unit is not used
frequently. This doesn't seem to be related to tender washing procedure
simply long term storage.
Debris under the exhaust diaphragm. Gravel off marine bottom - drift
wood when used in rivers. Easy to correct.
Odin:
Metal shavings, the product of mongrelling the first stage threads,
damage the silicon sleeve (or possibly the first stage seat and piston).
The servo valves we have received here seldom last 12 months before
commencing to leak. These have to be replaced at some considerable cost.
Occaisionally I have to replace the sleeve holder because the very small
bleed hole is blocked by corrosion. This only happens in hot countries.
That's all folks, apart from the flutter.
Also to those who responded to yesterday's post about Antarctica,
there's virtually no way to get there to dive unless you are attached to
a research programme (NSF or NZ).
