I recently purchased an Aeris ION regulator. I like it a lot except for one issue. The first stage often makes an irritating noise during exhalation which sounds like a high pitched "groaning" sound, it's almost like you're hitting a harmonic, as with a wind musical instrument. kinda annoying. any ideas?
also, does anyone know which position for the pre-dive switch is the "pre-dive" position? I assume it is up, but the documentation is unclear?
thanks for any feedback or input.
