The T-Wand is made in Washington, USA. Each T-Wand is packed in a heavy-duty transit case with a fabric holster,
wand standard, and instructions. The T-Wand is guaranteed for one year following the invoice date against failure
caused by defective material or workmanship. For questions about using your wand, please contact NMT Biology
([email protected]; 360.596.9400). If your wand is malfunctioning, please contact NMT Technical Support
([email protected]; 360.468.3375).

Step 5
– Pick the fish up from the ground, out of a hold, or off of a
table. We recommend holding dead fish by the gills to keep them
from swinging away from the wand. Sampling live, unanethestized
fish is easiest with a partner who can hold the fish for you.
Step 6
- With the back of the wand (the side with the arrow) in
continual contact with the fish, rub the wand along the snout from
the front of the mouth to behind the head with a very quick up and
down motion so that the entire sensor head passes over the fish in
both directions. Keep the long axis of the arrow parallel to the spine.
The arrow indicates the direction and minimum length of the pass.
Move the T-Wand quickly! A single up/down pass across the back of
the head is all that is required for coho and most Chinook. Wand
male Chinook larger than 1 m across the back of the snout and on
both sides of the head, over each eye.
If a tag is detected, the T-Wand will beep and
the indicator lights will come on.
Using the T-Wand Detection Standard
The Detection Standard is used to test the wand function and to
practice the wanding
technique. Hold the
plastic end of the
standard against the T-
Wand. Move the wand
briskly (that is, as fast as
striking a match) up and
down in the direction of
the arrow and for at
least the full length of
the arrow. The T-Wand
should indicate a tag
detection. If not, try
moving the wand faster,
making a longer pass, or
holding the standard in your fist with the plastic end against the
wand to create a larger contact surface. If you are still unsuccessful,
replace the batteries, and if that did not solve the problem, please
contact NMT.
Maintain contact
between the fish
and the wand.
Hold the
fish still
.
Move the
wand quickly.
Maintenance
Batteries: The T-Wand uses two high quality
alkaline AA batteries that are inserted into
the handle. If the batteries need to be
replaced, the wand will not power up. There
is no indication of when this will occur, so we
recommend that you
always carry fresh
batteries.
Unscrew the battery cap to replace the
batteries. Do not over-tighten the cap. The o-
ring is designed to provide a waterproof seal
with light pressure from the battery cap.
Screw it down only until it is finger tight.
Further tightening may damage the T-Wand.
After sampling, use a soft brush or cloth to
clean off any dirt and fish tissue.
When needed, disinfect using standard
practices.
Remove the batteries for long-term storage.
Hold the detection standard still
with the black plastic base against
the wand.
