what you're asking is a bit confusing since you say "no TE probe" and also
"no electronic compensation"...
I think you are asking which Variometers will work "with just "Pitot/Static"
which will then be some form of "electronic compensation"...
First, let me say I'm often asked about which TE Probe is best for a
particular variometer, Though there are some probes that do work better
with particular gliders, if you understand that TE is purely a compensated
Static system you'll realize that the brand of variometer has little effect
on which type TE probe is used.....the variometer only "sees" TE compensated
static, or static as good as it is delivered to the variometer itself. This
being said, any variometer can work with normal "uncompensated "static", the
end result will then of course be "Stick thermals" without the TE balancing
act.

There is quite a list of variometers that have do work with electronic
compensation, in fact some going back to very early designs used this, some
not so well, some very well....
RICO VA and VAS were TE compensated while the VACS used Electronic TE
Many early "Richard" Ball variometers used "E" TE.....
Cambridge attempted this with MKIV Variometers
I'm sure there were others
most of the above had mixed results, usually not the best unless the user
had some intimate knowledge of the system and was willing to tinker
IMHO one of the best early "E" TE Vario's came from Westerboer, with the
VW910 then also other good systems from Zander, Peschges and others.
Almost all later "high end" flight computers have "E" TE available or allow
use of TE probes
Borgelt B100 and the SN-10 that came from this system can use "E" TE
Cambridge 302's can use "E" TE
All LX Navigation and Filser systems have excellent "E" TE and are easily
user configured in programming to adjust the compensation, I've used these
both with probe and "E" TE and been equally pleased with either set-up.
I'm sure there are others I have not mentioned

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