Robert,
Bohli makes a taught band vario with a diaphragm compensator. Once very
popular in Europe, Don't know about now. Still available from Bohli, and
support service is excellent. Very expensive. Reichman's book tells you how
to make one yourself, I think.

Cheers!

Hello! Can someone tell me which compensated varios do not need a
total energy probe? (no electronic compensation) Thanks a lot! Robert
