When not using headphones, keep the 
rubber cover closed to protect the control 
box electronics from moisture and dust.

ACCESSORIES

Skid Plate

A skid plate comes as 
standard with the detector. 
If it wears out from 
excessive sweeping along 
the ground, accessory 
skidplates are available 
for purchase.

Environmental Cover

Protects the control box 
from environmental conditions 
such as rain and dirt.

Accessory Coils

 

Are available in different types 
(Concentric and Double D), sizes and 
frequencies. These coils are suitable 
for different ground conditions and 
specific targets.

The use of 

headphones

 while 

detecting, has many advantages. They 
block out external noise such as wind 
and traffic, allowing you to listen more 
closely to target signals. Headphones 
also minimise disturbance to other 
people in the area and they extend 
battery life.

The X-Terra 70 is able to save separate 
settings for both the speaker volume 
and headphone volume, switching 
from one to the other as soon as the 
headphones are connected

(Volume, pg. 32).

Ensure that the headphone volume 
does not reach an extremely loud 
level. This may increase the risk of 
hearing damage.

Connecting Headphones

Always use headphones with a ¼“ jack.

Open the rubber headphone cover 
located on the left hand side of the 
control box.

Plug the headphone jack into the socket.

When the detector is turned on, the 
headphones icon will appear on the 
LCD to indicate that the headphones 
are connected.

To attach an accessory coil:

Turn the detector off using 

POWER

Follow the steps of 

Coil Cable Assembly 

(pg. 7) 

and 

Connecting the Coil (pg. 5)

 in 

reverse order to disconnect the coil 
from the detector.

Repeat the same steps in the correct 
order to connect a different coil.

Turn the detector on using 

POWER

Short Shaft

A short shaft is available 
to decrease the length 
of the detector.
