Tesoro Outlaw Operator's Instruction Manual page 24

The ALL-METAL MODE will detect all metal. Use this mode for pinpointing objects,
determining the amount of "trash" metal in an area, to recover all items including iron, or for
gold nugget hunting. The Discrimination (DISC) MODE allows the discrimination of some types
of metal. Use the DISC MODE when "coin shooting" or jewelry hunting to eliminate some of the
"trash" metal.
The ALL-METAL MODE has two options: AUTO tune or no auto tune. When the switch is in the
AUTO position, the Outlaw will slowly retune the machine to bring back the threshold tone. This
means that the signal on a target held stationary under the coil will slowly fade back to threshold
level. This mode is recommended for most ALL-METAL hunting as it provides the most
stability.
When the switch is in the center position marked ALL-METAL, there is no auto tune. The signal
from a target held stationary under the coil will not fade until the RETUNE button is pressed.
This mode is useful for precise pinpointing, identifying target size, line tracing and ore
sampling. For precise pinpointing, find the searchcoil position near the strongest signal. Hold
the RETUNE button down to retune the Outlaw to the current target. Release the button, and the
signal as you move the searchcoil should be very small.
Note: Pressing the RETUNE button slightly in the Discrimination mode will change the mode to
ALL-METAL no auto tune. Pressing the RETUNE button completely will enable the fast retune.
With practice, you should be able to use the RETUNE button to change the mode and retune a
target to quickly pinpoint a target.
SETTING THE DISCRIMINATION LEVEL
The DISC LEVEL control is used to adjust the detector's response to unwanted trash metal
when operating in the Discrimination MODE. At the lowest setting (MIN), the detector will
ignore most iron objects, but will still respond to light foil, bottle caps, pull tabs and most other
