TARGET INDICATIONS  

OUTDOOR DETECTING  

Note: 

There is a wide variety of metals and no target can be identified for certain 

until unearthed. This table is for general reference only.

1.Find a place outside where there is no metal.
2.Place a sample you want to find on the ground.
3.Press POWER to power on the detector.
4.Hold the search coil level to the ground about 1~2 inches above the surface, 
   slowly move the search coil over the area where you placed the sample, sweep  
   -ing the search coil in a side-to-side motion.

● 

Never sweep the search coil as if it were a pendulum. Raising the search coil 

while sweeping or at the end of a sweep will cause false readings.

●  

Sweep slowly, hurrying will cause you to miss targets. 

●  

It’s better you sweep the search coil from side to side in an arc line of 3 inches 

motion and keep the search coil parallel with the ground
If the detector detects the item, it sounds a tone, and an arrow above the target 
icon appears. Also LCD displays the digital value of target as well as the depth.
If the detector does not detect the item, make sure that the mode is set correctly for 
the type of metal you’re searching for. Also make sure that you’re moving the 
search coil correctly.
