I think it's possible for a double or triple, IF, he was to produce a certified ELD. But I think even that would be short lived.
There's 96 other choices out there. I'm sure all of them have sold at least a few, if not dozens or even hundreds. This would be starting out with zero, unless someone got overly enthusiastic and bought one before it got certified.
But even if....., it would be a long slow slog to reach profitability.
