I checked out the field trial web page
that
Ray pointed me to. It is *exactly* what
I
was looking for.
It led me to this web page for a firm
that
manufacturers radio-finding equipment,
both
for researchers (ever wonder where
those
bear collars come from?) and for field
trial
guys who need to find lost dogs. Check
out
their dog recovery equipment page:
(Again, if this URL line appears wrapped, it
is
supposed to be
one line.)
Like most radio stuff, the range is
undoubtedly better in flatter
terrain.
Alas, the receivers are much more
expensive! Evidently these devices
are
also now being used for Alzheimer
patients!
