DeepTech DISCRIMINATOR, Manual

         Practical use in the Discriminating mode of operation 

-In the prepared from your test field add a ferrous utensil with a 
diameter of 5-6” and bigger, and at 6 – 10 feet, some other iron 
instruments. 
-Tune the detector in the Manual Mode far from any metals, and 
after that switch it to the Automatic Mode of operation, as 
previously done. The “Sensitivity” control is on the OFF position. 
Now Passover all the targets repeatedly, moving with a normal 
pace. Note, that the detector gives an audio response to all of your 
targets in the test field. Iron targets are indicated by the red 
(ferrous) LED light on the intensity meter. This should work most 
of the time, it is the magnetometer which discriminates the ferrous 
from non-ferrous metals. 
-Turn the Sensitivity control to the MAX position. Wait till the red 
light of theindicator fades. Switch to A/D position of the toggle 
switch (full discrimination). 
-Now pass again repeatedly over your sample targets. Note, that 
the non-ferrous plates, even if buried deep in the ground, will 
produce a good audio response without a red light of the indicator. 
-The LED indicator will illuminate on all the remaining iron 
targets, no matter their size, and audio discriminated. The smaller 
target won’t produce an audio response. 
-The bigger targets will produce an increasing sound, when you 
approach the coil to them, followed by a sharp lapse into silence, 
together with an illuminating LED indicator. 
-This mode of operation allows avoiding the unnecessary digging 
of the unwanted ferrous targets. The detector discriminates all the 
ferrous objects lying in the upper arable layer of the ground. The 
discrimination is not affected by the size, the oxidation and the 
aging of the ferrous objects within the detection range of the
