Sweeping the coil The Explorer II will perform at its best when the coil is kept in close proximity to the ground. This will increase detection depth and Figure 5.2 Sweeping the coil response to small objects. - Page 4 THE MINELAB EXPLORER II www.minelab.com QUICKSTART DISPLAY easy reference The Quickstart display visually represents everything from target details to the Explorer II’s operating settings.

Coins discrimination pattern functions are explained in the next few pages. Two-dimensional discrimination explained The Explorer II rates detected objects according to their conductivity (like most traditional detectors). What makes two-dimensional discrimination unique is a rating of the same object's ferrous content. - Page 7 (e.g. jewelry) and eliminate signals from unwanted material (e.g. nails). Interpreting target responses The Explorer II can be programmed Conductivity in a number of ways to discriminate • Objects with high conductivity (e.g. large silver coins, copper...
- Page 8 THE MINELAB EXPLORER II www.minelab.com Introducing Discrim Discrim (an abbreviation of Discrimination) instructs the detector to accept some types of targets and reject others. It uses Smartfind's two-dimensional discrimination, allowing you to specify one or more target patterns for detection.

THE MINELAB EXPLORER II www.minelab.com MODIFYING THE DISPLAY Full screen display Figure 5.9, 5.10 If you wish to enlarge the Smartfind or Digital display during detecting, it is possible to instruct the detector to remove the display border and other screen elements leaving only the target details displayed on the full screen. -
Page 13: Adjusting Sensitivity
THE MINELAB EXPLORER II ADJUSTING SENSITIVITY Sensitivity control The sensitivity bar indicates how responsive the detector is to a target in the presence of ground noise and/or electromagnetic interference. The degree of sensitivity is increased by pressing the top shift button and decreased by pressing the bottom shift button (on the left side of the control panel). -
Page 14: Adjusting Threshold
ADJUSTING THRESHOLD Threshold control The Explorer II usually emits a constant tone or threshold ‘hum’ in the absence of a target. The threshold setting controls the audible level of this sound during detecting. Minelab recommends setting the threshold to a comfortable audible level in the early stages of your... -
Page 15: Audio Response
THE MINELAB EXPLORER II AUDIO RESPONSE The Explorer II emits a target audio response that varies in pitch and volume depending on what type of object it detects. Pitch of response Figure 5.13 Generally, a target that is highly conductive (e.g. a large silver coin) emits a high pitched signal. -
Page 16: Audio Menu
Main Menu > AUDIO As mentioned earlier in the section on Audio Response, the Explorer II emits a target signal that varies in volume and pitch depending on the object it detects. Generally, large targets or Figure 5.14 The Audio menu targets close to the ground surface emit the loudest signal. -

Limits This sets the upper limit of all tones emitted by the Explorer II. Minelab recommends setting the upper limit to the highest frequency you are comfortable with. You can test the upper limits with a highly conductive object (e.g. -
Page 20: Audio: Adjusting The Sounds
Constant Main Menu > Audio > Sounds > CONST Selecting CONST eliminates the variation of the pitch upon detection. If selected, the Explorer II will emit a consistent tone regardless of the target detected. Conductivity Main Menu > Audio > Sounds > CONDUCT Conduct is the factory preset and Minelab’s recommended option. - Page 21 THE MINELAB EXPLORER II Ferrous Main Menu > Audio > Sounds > FERROUS Selecting FERROUS adjusts the tone according to the target’s ferrous content (the horizontal axis of the Smartfind screen or the first number in the Digital display).

Page 23: Pinpointing The Object
For example, Iron Mask is activated and the Explorer II has detected the approximate location of a non-ferrous coin but ignored the rusty nail buried nearby. Selection of Pinpoint instructs the Explorer II to respond to all metals positioned directly beneath the coil. -
Page 24: Using Pinpoint
Using Pinpoint Figure 5.21 Once the Explorer II has found the approximate position of a target it is necessary to locate its exact position using Pinpoint. Move the search coil to one side of the approximate target STEP 1 location and press the PINPOINT shortcut button. -
Page 25: Recovering The Object
THE MINELAB EXPLORER II RECOVERING THE OBJECT For this procedure you’ll need: a knife or trowel, a small spade and a sheet of plastic. Once the object has been pinpointed, clear the surface of STEP 1 loose material and check again for the signal. If there is no signal then the object is amongst the surface material. -
Page 26: Selecting Targets
Smartfind’s two-dimensional discrimination. If you wish to detect one or more object types it is necessary to specify which the Explorer II should detect or reject. Figure 5.22 Quickstart’s Main Menu Choosing SELECT from Quickstart’s MAIN MENU (Figure 5.22) displays the SELECT target list (Figure 5.23). -
