THE MINELAB EXPLORER II

TESTING TARGET AUDIO RESPONSES tutorial!

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.
