I had a Digitar and left the wind unit up as a backup when I moved to a Weather Monitor 2 and then a VP2. That thing lasted far longer than my first WM2 anemometer/wind vane. It'll work.You just need to figure out the wiring. As I recall, the Digitar used 2, 3 conductor audio style cables.
Heck I think I still have that around here somewhere...
