Best performing Vario?

I'm also surprised that your experience with SYM (See You Mobile for
those of you lacking the coded language) you find troubling to exit
the thermal assist function. All you do is tap the screen one time,
that's it!

Last weekend, I found myself at pattern altitude, ready to landout,
and then stumbled into a 0.3 knot thermal which I probably wouldn't
have been able to center if it weren't for having the thermal assist
function in SYM. That saved the day as it brought me up to final
glide, 26 miles from home. I was 10 seconds from dropping the gear
and committing to a land out. One wrong turn out of the thermal and I
was dropping the gear, so this function proved its effectiveness to
me.
