Sensitivity Modes 

Now for a bit of Physics!  

E-Trac has three sets of internal signals used to identify targets.  E-Trac continually measures the 

magnetic 

ground interference

 that affects these signals and adjusts the level of Sensitivity 

individually

 for each set of 

signals, to provide the most stable Target ID.

Most ground types cause some interference and E-Trac uses this to adjust the detector to the correct Auto 
Sensitivity.

Auto Sensitivity may not work well on the wet and transition areas of salt water beaches (it would be fine 
on dry sand areas) as they do not typically contain magnetic materials.

Note: 

Minelab recommends beginners use E-Trac in the Auto Sensitivity mode unless detecting on a beach 

where Manual is recommended.

A completely 

new feature

, the Sensitivity Gauge has two indication bars in both Auto and Manual and a 

numeric Sensitivity value above the gauge.

Auto sensitivity (A)

The left hand side bar indicates the highest Sensitivity level that either the high, 
medium or low channel is operating in.

The right hand side bar indicates the “Suggested” Sensitivity level.  This is an 
average Sensitivity Level of the internal signals.  Each internal signal is set to 
a different level of sensitivity individually by the detector to provide the most 
stable Target ID’s.

For example, if E-Trac determines the Sensitivity Levels for each signal to be 20, 
15 and 10, the left hand bar and the numeric value of the Sensitivity gauge will 
display 20

The ‘Suggested’ Sensitivity (the right hand bar) will display the average of all 
three channels, which will be 15.

Manual Sensitivity (M)

The left bar and numeric value indicates the level of Sensitivity you have set.

The right bar indicates the ‘Suggested’ Sensitivity level the same as it does in Auto (A)

The important difference between Auto and Manual is that all of the 3 channels (H, M & L) are set to the 
same level in manual and if set too high may cause unstable target ID’s.

For example, if the Suggested Sensitivity determined by the detector is 15 and you set Manual Sensitivity 
to 20, all channels are set to 20.  If one channel is affected by the ground conditions then Auto would 
normally reduce the level for this channel.  In Manual it is not reduced and stays set to 20 so the ground 
interference may cause false signals and unstable ID’s.

Auto Sensitivity Range + 3 to – 3

The Sensitivity can be increased by + 3 levels or decreased by – 3 levels.

This innovative new feature allows you to be [more aggressive] or [conservative] while operating E-Trac 
in Auto Sensitivity.  Increasing by 1, 2 or 3 sets the Auto Sensitivity higher than the Automatic setting by 
the number of levels you select.  Similarly, decreasing would have the opposite effect but bear in mind 
sensitivity to smaller items could then drop off somewhat.
