LCD IDENTIFICATION SYSTEM
The LCD will also show you an indication of the type of target you 
have found, in conjunction with the audio tones, by showing you 
a number preceded by a “-” or “+” sign.  The target identification 
system works as follows:  
When in either search mode (ALL METAL or DISC), a target    
will produce a number between 0 and 36 indicating target    
type.
In addition, the - or + sign in front of the number       
indicates whether the target is ferrous in nature
(an iron target) “-” / or nonferrous (a non-iron target) “+”.  
The target I.D. numbers correspond 
to the following target types: 
    All negative (-) numbers:  Iron
    +0 to +8:       Foil
    +9 to +11:       Nickel
    +17 to +18:       Square Tab/Brass
    +20 to +22:      Zinc Pennies
    +28 to +30:      Copper pennies, dimes
    +30 to +34:      Quarters
    +34 to +36      Silver        
Remember, this Numeric I.D. system is activated in either
the All-Metal or Disc. modes (although the 4-tone audio
I.D. is only active in the Disc. mode). 
Also, the discriminator can silence the audio for certain 
targets, but the two-digit I.D. will always reveal the target 
identity.
