ASSEMBLY

1

Position S-Rod upright.

2

Rotate the LOCKING COLLAR fully in the counterclockwise direction.

3

Insert your finger inside the tube and make sure the INTERNAL CAM LOCK is flush

with the inside of the tube.

4

Insert the MIDDLE STEM into the S-ROD,

with the SILVER BUTTON pointed upward

5

Rotate  the  MIDDLE  STEM  until  the  SILVER

BUTTON locates in the hole.

6

Twist the LOCKING COLLAR fully in the clockwise

direction until it locks.

7

Repeat this process on the LOWER STEM.

8

Using the BOLT and KNURLED KNOB, attach the

SEARCHCOIL to the LOWER STEM.

9

Adjust the LOWER STEM to a length that lets you

maintain a comfortable upright posture, with your arm

relaxed at your side, and the SEARCHCOIL parallel

to the ground in front of you.

10

Wind  the  CABLE securely  around  the  STEMS,

leaving slack at the bottom.

11

Connect CABLE PLUG to housing.

Do not twist the Cable or Plug. Turn Locking Ring

only.  Use  minimal  finger  pressure  to  start  the

threads. Do not cross-thread. When the Locking

Ring is fully engaged over the threaded connector,

give it a firm turn to make sure that it is very tight.

When the Locking Ring is fully engaged over the

threaded  connector,  it  may  not  cover  all  of  the

threads.

12

Tighten both LOCKING COLLARS.

SEARCH TECHNIQUES

Target Verification

After detecting a target, do the

following:

1. Walk around the target in a circle.

2. While circling the target, continue

sweeping the searchcoil across the

target.

3. Sweep once every 30° or 40° of the

circle.

If the tone does not change and

the Target-ID value is consistent as

you circle the target, you can be

highly confident of the target's

identification.

If the tone or Target-ID changes

as you circle the target, you may

have multiple targets or an

irregularly shaped object.

If the tone completely disappears

at different angles, the target may

be trash or a low-value metal.  

If you are new to metal detecting,

dig all targets. With practice in the

field, you will soon be able to

correlate audible and visual target

feedback with certain types of metal objects.

Pinpointing in Discrimination Mode:

1. Sweep over target in narrowing side-to-side pattern.

2. Take visual note of spot on ground where “beep” occurs.

3. Step 90° to the side of the target.

4. Sweep searchcoil over same area, at 90° to 1st sweep pattern.

5. This pinpoints the target location with an “X.”

SEARCHCOIL MOVEMENT

When  swing ing  the  searchcoil,

be care ful to keep it level with the

ground about 1/2 inch from the sur -

face.  Nev er  swing  the  searchcoil

like a pen du lum.

Note: Very tall users can purchase the optional Extended Lower Stem (TUBE5X), for extended reach.

Caution:

Forcing in MIDDLE STEM with CAM LOCK raised may form a burr on

camlock. If this happens, remove burr with knife to allow insertion.
