True, including the $2.50. In my case I kept all the original steam-era instruments, so there is nothing essential for flight that I would lose. Actually my motivation for buying it is that my ammeter has developed a bizarre fault where it SOMETIMES misreads, so now I have battery voltage and I don't need it. Also of course the data recording capability, which is really the big advantage. I had a first-generation GEM before and this is a lot better - more precise, easier to read, plus the storage.
