One of my concerns about some devices is the amount of attention needed from
the pilot. Head-down looking at an instrument time, must be kept to a
minimum for safety reasons.

Themi uses two bright, LED lights mounted near the top of the instrument
panel (typical) so they are in your field of view.
The light or lights, only come on if Themi has a suggestion to make, so the
light(s) are easy to notice without ever looking at them.

Themi is most valuable on blue days, or at low altitudes, when clouds are of
little help. Themi really works!
