36 Garrett Metal Detectors

  Tip for narrowing the detection area: Large targets can 
produce wide signals while pinpointing, making it difficult 
to precisely locate the target's center. To help pinpoint, the 
detector can be retuned to the target to narrow the detection 
field as follows.
  While holding down the Pinpoint pushbutton, move the 
coil toward the target until the LCD just reaches a full-scale 
response. Then, quickly release and depress the Pinpoint 
button again to retune the detector and narrow its detection 
field. Continue moving the searchcoil toward the target to 
find its central peak response. If needed, repeat the retune 
process to further narrow the target's response.
  A quality hand-held pinpointer such as Garrett's Pro-
Pointer is a recommended accessory item to speed the target 
recovery process and to aid in locating secondary targets.

  Coin Depth Indicator—The depth of a coin, or similar sized 
target, is indicated in 5cm increments. Note: targets larger 
than a coin may display shallower than actual depth while 
targets smaller than a coin may display deeper than actual 
depth.
