Take some time to become familiar with how the Explorer II
responds to various metal objects. This tutorial is
designed for Smartfind’s Iron Mask and Discrimination
functions. Repeat the procedure to familiarize yourself
with both.
Gather a collection of different metal objects like a rusted nail,
pull-tab, brass button, aluminium foil, various coins, and some
gold and silver jewelry. Take the detector outside, away from
known electromagnetic devices or metal objects.
STEP 1 Find an area of ground without targets.
STEP 2 Lay objects in a line, sufficiently spaced apart to allow
the coil to pass between the objects.
STEP 3 One at a time, pass the coil across the test objects. The
detector should ‘beep’ on the non-ferrous objects and
ignore the ferrous objects.
STEP 4 Take note that as the coil is passed over the nail, the
threshold ‘hum’ disappears, indicating that the object
ignored was ferrous.
STEP 5 Passing the coil over different non-ferrous objects will
produce different signal tones. Objects with high
conductivity, such as silver or lead, produce a high-
pitched signal tone while objects with lower conductivity,
such as aluminium foil, produce a lower pitched signal
tone.
With experience (and adjustments to the Audio settings) it will
be possible to use the signal tone from an object to accurately
determine the type of object discovered before recovering it
from the ground.
