At DEMA, I'd expect much more pointed scrutiny:
- What is the service interval?
- When will the service training be available and how long will the course be?
- How much is the service kit?
- Do I have to take my reg to the dedicated LOB charging station and recharge it every night?
- Does a regulator with a built in tank-marker lamp really qualify as a significant innovation?
Who will be able to service it ?
Dive shop techs are not electronics techs.
