[PSUBS-MAILIST] air compensation

[Alan James via Personal_Submersibles]

Jon, can you describe a reasonable & cheap oil compensation system?All the commercial units & X navy literature describe an over-pressure system that is not easy to build.I would consider the air used in an air compensation system to be minimal compared with blowing your ballast tanks every dive. Scuba systems seem to have very few failures so, that shouldn't be an issue.Alan
