Anyone have played with one of these expensive thermal cameras?

We will have an update this year - we've been comparing a high end camera
with a high end calibration system against a 'relatively' inexpensive hand
held.
Either has to be used when ambient temperatures are used - best at night.
During day, solar radiation hitting outside of hive obscures temperature
of bee population inside.
One can get misreads from combs full of honey.
