HOW TO TUNE
1. Check batteries on both Transmitter and
Receiver.
2. Place the Receiver Sensitivity Switch in the
NORMAL position.
3. Turn SENSITIVITY knob to 7.
4. To turn ON, pull POWER switches on Receiver and
Transmitter.
5. Pick the unit up by the handle and balance it so
that it is level with the ground and at normal carrying
height (arms length). For a deeper search, hold with
the carrying strap which has been fully lengthened.
You will need to hold the instrument at this lower level
while tuning if you plan to use it lowered. On some
highly mineralized ground and some asphalt, you
may not be able to use it with strap fully lengthened.
You will know this if you cannot reach a “null”. Not
reaching a null can also indicate the presence of
nearby metal.
CAUTION: Never attempt to tune the TW-6 in the presence of metal
objects like cars, metal walls, roofs or heavy metal reinforcements
in any structure. Their presence will make proper balancing
impossible.
6. Turn front knob on handle counter-clockwise, until
lowest meter and speaker indications are reached.
You have reached the lowest point if a 1/8- l/4th turn
in either direction results in an increase in sound and
meter reading. If at the lowest point there is still sound

4. With the Transmitter still on its back, align the two
holes in the panel of the Receiver with the knobs.
5. Turn the lower knob of the two knobs until it is
“nger-tight”. Turn the knob with the arrow until the
spring is compressed and the panel is pulled within
3/8” of the handle at the end.

to cross back past the path of this conductor and will induce a
certain amount of signal into it. This signal can mislead you when
tracing it out.
If you’re working on pavement, simply lay the Ground Rod/
Harness Assembly on its side, parallel to the conductor in
the direction of the tracing. Weighting it down with a rock or
someone standing on it makes it a better ground contact. If the
plate is weighted down in a puddle or at least if the pavement
is wet, tracing distance is improved. You may pour some water
on the pavement to improve ground contact.
