Small fixes (replacing a hose) I'll do myself, big fixes go to the guy that has the work bench with the magnehelic.
I am more concerned about the how my regs are maintaining IP vs inches is res from the 2nd stage.
I have a nice magnahelic and will check my regs at rebuild and from time to time, but a 1st stage Hp seat going bad can potentially go unnoticed during a pre dive check and can really bite you in the arse if it goes full TangoUniform during a dive.
Whether you self service, or use a trusted tech, knowing how to trouble-shoot and diagnose reg problems is critical for anyone I dive with.
