STEP 1 Press the shift button next to the full screen icon at the right of the control panel.
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. Noise Cancel So that you can detect in best conditions, we would advise you to always choose the channel with least interference before beginning If the detector becomes noisy and you suspect electromagnetic interference, change to a better channel before adjusting sensitivity.
THE MINELAB EXPLORER II www.minelab.com 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 detecting session, as this feature is designed to highlight the variations in signal response which often indicate detection of a target.
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 Figure 5.13 Target sounding response Generally, a target that is highly conductive (e.g. a large silver coin) emits a high pitched signal. A low pitch is sounded for less conductive targets. Large targets or targets close to the ground surface emit a louder signal.
THE MINELAB EXPLORER II www.minelab.com AUDIO MENU Features accessed through the Audio menu allow you to define the various audio properties of your Explorer II. Introduction to the Audio menu Figure 5.14 Main Menu > AUDIO Figure 5.14 The Audio menu Headphones Use of the Explorer II with headphones will allow you to discern subtle variations in audio 5 response and lessen exposure to QUICKSTART adverse conditions (i.e. wind) which may distort sound from the speaker.
THE MINELAB EXPLORER II AUDIO: ADJUSTING THE VOLUME Introducing Volume Figure 5.15 Main Menu > Audio > VOLUME The VOLUME screen of the Audio menu displays two slider controls: MAX LIMIT and GAIN (Figure 5.15). Figure 5.15 Volume adjustment screen NOTE To test sounds upon selection it is necessary to move the coil across the target.

THE MINELAB EXPLORER II www.minelab.com Normal alisasing 5 Figure 5.16 Volume gain settings Figure 5.17 Volume gain preset Gain Figure 5.16, 5.17 Main Menu > Audio > Volume > GAIN (adjustment) Volume gain affects the way the detector amplifies target audio responses in respect to the strength of the original signal. 5 QUICKSTART Looking at figure 5.16, it is clear that with a setting of 1 the sound produced will be proportional to the strength of the signal for the whole range of signals.
THE MINELAB EXPLORER II AUDIO: ADJUSTING THE TONE Introducing Tone Figure 5.18 Main Menu > Audio > TONE Figure 5.18 Tone menu Tone is the frequency of sound emitted on target detection. It is important to experiment with tone settings and listen carefully to tone variations during your detecting. To test variation in tones upon selection it will be helpful to move the coil across a few different targets spaced apart. Threshold tone Threshold Tone allows you to adjust the tone of the threshold ‘hum’.
THE MINELAB EXPLORER II www.minelab.com AUDIO: ADJUSTING THE SOUNDS Introducing Sounds Figure 5.19 Main Menu > Audio > SOUNDS Figure 5.19 Sounds menu The SOUNDS menu allows you to define how the pitch varies with target characteristics. This can be a very useful feature in identifying targets in close proximity to one another. It is possible to instruct the detector to emit a distinct sound responding to an object’s ferrous characteristics, rather than its conductive properties.
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). A low ‘blaat’ tone denotes a highly ferrous object, displayed on the left of the screen and having a high ‘Fer’ number. A high pitched ‘squeak’ tone denotes a non-ferrous target, displayed on the right of the Smartfind screen and having a low ‘Fer’ number.
THE MINELAB EXPLORER II www.minelab.com TESTING TARGET AUDIO RESPONSES tutorial! Take some time to become familiar with how the Explorer II responds to various metal objects.
