Hi,

I agree. I think it is extremely tough to rely on the variometer reading
when trying to center a thermal if you don't have a TE probe. Also, it is
tough to know whether a thermal you encounter while cruising is worth
stopping for.

Yes, I'm biased because I sell them, but that is my honest opinion.

Well it would seem that total energy is not required if I folllow this
post.
All I can say is that any speed variations without TE will lead to stick
lift and will make it much harder to centre that thermal as a small back
pressure on the stick will show lift and vice versa
Basic TE is nothing to do with interthermal flying speeds but reduces the
vario indication changes due to speed variations whilst circling rather
than lift.
In my view absolutely essential!(unless you can circle with no speed
variation at all)

OK, I'm 99% sure that this won't be an issue but everything in the
literature for the Tasman vario's says it only needs connected to a
total energy port. No total energy on the Cherokee II but I suspect
the tasman will work OK hooked to static just like my current Winter
vario. It will just be non compensated as expected. Is there any
reason why this wouldn't work?
