White’s Electronics Bullseye 2 - Manual (Page 4)

Field use
1. Press and "hold" the ON button continuously for the
detection of metal. High intensity LED will also be turned on
for target illumination at the same time. (If the unit beep or
vibrate without any metal target nearby, it is very likely that
the sensitivity setting exceed its allowable range. Please
adjust sensitivity according to Sensitivity Adjustment
session.)
2. High intensity LED also indicates the Bullseye is ON and
ready to detector any metal that nears the end of the probe.
3. When the button is released the Bullseye reverts to OFF,
light is also turn OFF.
4. The Bullseye's automatic tuning requires very little motion
or movement of the probe in order to detect a metal and
ignore the ground. Practice with a coin or other small metal
to become familiar with this very slight movement required
to pinpoint a metal.
5. The best method on a salt water beach is still a sand scoop.
The Bullseye may detect conductive salt concentrations or
pockets as is common with (VLF) type metal detectors.
