Dear Parents and Supervising Adults,
Setting Up the Detector and Transmitter
WARNING: An adult should insert and

Follow the same steps for the detector, using two
new AA (1.5-volt, type LR6) batteries.
Once you have chosen a spot for your transmitter
and placed it there (or someone else has hidden
it), you or another fellow detective can use the
handheld detector to locate it.
To do this, go from room to room pressing the red
trigger on the detector to evaluate the ultrasonic
sound waves, following the display on the
The yellow LED in the middle indicates that your
device is active. When you are within a 15-meter
(50-foot) range of the transmitter, the LEDs to the
right and left light up. The closer you are to the
transmitter, the brighter the lights will become.
The LEDs also tell you in which direction to walk
to get closer to the transmitter. If the LEDs on the
right are glowing brighter than the LEDs on the left,
your detector is telling you to move to the right.
A bat’s ears work the same way. If the sound waves
reach the right ear faster than the left ear, the bat
knows that the item the sound waves are bouncing
off of is toward its right and turns accordingly.
How Your Spy Location Tracker Works
Turn on your transmitter by sliding the switch on the
bottom of the device to the “I” position. The red LED
will light up as soon as the transmitter is activated,
sending inaudible ultrasonic waves into space.
Hide the transmitter in a place where the signal
won’t be obstructed, like next to or on top of a
box containing your treasures, or on a bookshelf
where you store secret documents or have
evidence hidden. You can even use it to mark
meeting points or a person’s whereabouts. Try
hiding your transmitter under a thin blanket or
behind a cabinet door to see if the ultrasonic
waves are able to pass through to the transmitter.
WARNING! Not suitable for children under 3 years.
Choking hazard — small parts may be swallowed
