Old BCs (and wetsuits) should go to the trash. Regulators, OTOH, can almost always be made to perform like new without too much trouble.I believe they are going into the trash.
It took some will power to throw our
old BC’s into the trash.
Oh well …. Now we’ve got new stuff again.
Mikron service parts are really available. Put them up for the cost of shipping in the regulator classifieds. Someone will grab them.
