1.  Mode 

-  Indicates  which  detection  mode  is 

selected by highlighting the corresponding word on 

the LCD.

2.  target iD legend

 - A Target ID Legend is 

located directly above the LCD screen and indicates 

commonly  found  crime  scene  targets  and  metals.   

When a target is detected, the Target ID cursor will 

appear below the word that most likely indicates the 

type of target found, based on its conductivity. 

3.    target  iD  Cursor

  - The Target  ID  cursor 

is illuminated in the Upper Scale and indicates the 

probable identity of a detected target. 

4.    lower  scale

 - The lower horizontal scale, 

or  Notch  Discrimination  Scale,  indicates  the 

discrimination  pattern  where  the  CSI  250  will  or 

will  not  produce  an  audible  signal  when  a  target 

is  located.    This  scale  can  be  modified  in  both 

detection modes.

Csi 250 

Features

The  CSI  250  is  designed  with  Garrett’s  exclusive 

Graphic  Target  ID  technology,  which  indicates  the 

probable  identification of a target along a horizontal 

scale  that  reads  from  low  conductive  metals  (e.g. 

iron)  on  the  left  to  high  conductive  metals  (e.g. 

silver) on the right.
