to either of two working lengths (see
photos below). Unwrapping only one full
turn will make the probe 12.5 in. long.
Unwrapping both turns will make the
probe 24 in. long.
Each length incurs a tradeoff of probe
reach vs. probe rigidity. A longer probe is
obviously better for inspecting distant
objects. But when uncoiled to its
maximum length of 24 in., the probe
sags from its own weight, preventing it
from being extended horizontally. If the
12.5 in. length is sufficient to reach most
of your inspection targets, select that
shorter length; at 12.5 in., the probe is
light enough to be extended horizontally.
Whichever probe length you choose,
before you can use the unit you must
re-coil the unextended section of probe
within the channel inside the clamshell
and then squeeze the clamshell shut. To
protect the internals of the unit from
being damaged by a fall, an electrical
8
interlock prevents The PalmScope from
being powered on with the clamshell
open.

It's important to note that when re-
coiling the probe from either its short or
long extended length, you must wrap it
very tightly within the channel. If the
camera head has not cleared the probe
exit port as you
finish wrapping the
probe (see photo
at right), you will
not be able to
squeeze the clamshell shut. You must
start over.
ATTACH THREAD PROTECTOR
OR ACCESSORY
The PalmScope comes with four
accessories that screw onto the camera-
tipped end of the probe. Each accessory
has a specific purpose:
• The 45° mirror lets the probe see
around corners.
