we

as
100%.
This

you

Find
mode
The
Find-mode
provides
you
with
a
way
to
locate
a
downed
aircraft.
A
GPS
signal
is
currently
required
to
use
this
mode
(other
detection
modes
are
being
developed).
Install
our
TBS
GPS
module
or
TBS
BLACKBOX
logging
unit
(via
APM/NAZA
GPS)
to
the
BST-port
on
side
of
the
receiver.
In
normal
use
the
GPS
coordinates
are
continuously
updated
and
the
latest
data
is
displayed
on
the
“Find
Mode”
screen.
If
the
model
looses
power
you
can
review
the
last
known
coordinates
to
locate
your
model.

The
receiver
has
an
on-board
LiPo
battery
to
operate
in
beacon-mode.
This
allows
the
transmitter
to
send
the

to

after
