THE MINELAB EXPLORER II

QUICKSTART

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.
