I use the 302 on electrionic TE, my Sage is on a " B " box by Wil S. and a B-40
on the TE probe. The 302 works great and so do the others. The " B " box by
Wil S. is what I do most of my thermaling with, with weak lift I like the B-40.
The 302 is used for cruising and shows me what my climbs will be if I stop. I
use the DDV on the 302 along with the read outs on the 303 during climb so I
know when its time to leave. The 302 with the 303 is really a good setup. I
guess what ever you like is the best answer, fly with what you got and try it
several ways, then "you" decide. # 711.
