I also recommend spending $40 more and getting the Davtron C307PS
temperature probe (contact Davtron sales directly). This can
interface to the GTX-330 and will then display OAT and Density
Altitude. The little probe can poke through the fuselage in a
convenient spot (mine's just below/forward of the side pilot window).
I'm getting ready to replace my windshields and didn't want to poke
the analog probe through the new glass.


Thanks Dave. I'll talk to the shop and have them add it.
