Explorer SE Pro

Field Test Report

There's nothing better for a new detector model owner than to have a crowd of

onlookers gather around to ogle your new purchase and ask about its performance

and abilities while admiring its sleek appearance and asking for "a quick burn"

around the field to try it out.

To achieve such a crowd-pulling feat these days requires either a prestige badge or

an eye-catching appeal. This year's crowd-puller has both and appears to be the

new all black Minelab Explorer SE.

Such was the interest recently in this new model at a one-day event it had to be

handed around on a ten minute loan basis as so many wanted to take a closer look.

The entire build of the new detector is made up entirely of all black plastics which

accentuate the striking sharp lines. This is truly a high-tech and high-spec machine

and one which will continue to dominate in the "serious detecting" arena.

Improvements & Features

"3rd generation" Software features include:

• New "logical" Main Menu format, re-arranged "selections" to make

browsing easier with one hand.

• Now displays two separate screens, Smartfind and Digital - Learn and Edit

screens now accessed through Main Menu.

• New pin point -VCO type rising sound with improved volume on deeper

targets.

• New Iron Mask scale - now displays Ferrous range from 0 - 31 and AM = All

Metal.

• Fast turn on, quieter/faster turn off.

• Audio 1, 2 & 3 are now Long, Smooth & Pitch Hold respectively. Pitch Hold

similar to the BBS series of detectors.

• Faster loading of User settings.

• Factory preset Gain now set to 8 (used be 5)

• Stabilized Threshold in high-trash environments.

• New larger fonts.

• New updated detection results on Fer and Cond in Pin Point mode.

• Improved behaviour of the Depth indicator during detection and pin

pointing.

Hardware changes include:

• New colour, style and appearance.

• New thinner, lighter coil with better balance (weight reduction 60grms)

• New front keypad decal

• Current consumption reduced by 8% approx. prolonging battery life

increasing run time by 1 - 2 hrs.

Focus on New Features

The most important software changes are listed above however there are some

more that are not. An example of one would be in the Digital display whilst using

the large zoom screen, the icons which showed in the previous Explorer models as

coins, rings and tabs do now not show on Explorer SE. Instead, the entire pixel

space is given over to four huge and very tall numbers for Fer and Cond to enable

easy viewing of the numeric values assigned to every detected target.

The major changes will be discussed in more detail here and they include the new

RESPONSE sounds although Normal, Audio 1 and Audio 2 have not changed but

instead have been re-named as Long (Audio 1), Smooth (Audio 2) and Pitch Hold

(Audio 3). Normal response remains the same and no changes to it have occurred.

The big change is to Pitch Hold which is, an exciting new innovative audio choice

method for Explorer SE users and a lot of information can be gleaned from it which

will be described in greater detail below.

The Response option allows you to select the way targets sound upon detection.

These are described below. Each Response sound may work better in different

scenarios and you should quickly develop your own personal preferences.

1. Normal - when the target signal drops the audio blanks, giving a crisp end to the

target response. Normal allows the greatest differentiation between the ground

and a target, but has the potential to miss small targets in areas littered with

objects producing a target response.

2. Long - long audio lasts until the end of detection. There is no blanking at the

end of the target response. Long allows less differentiation between the ground

and a target.

3. Smooth - as opposed to the sudden change in audio response in Normal and

Long, Smooth offers a more gradual change/rise in audio response from ground to

target detection.

4. Pitch Hold - is identical to the normal response during detection. After blanking,

the threshold will return to the same pitch of the peak target signal. The pitch of

the threshold will not change until a new detection is made. The Minelab

Sovereign series of detectors varies the pitch of an audio signal depending on the

conductivity of the target: i.e. a highly conductive target produces a high-pitched

tone, while a less conductive target item produces a lower-pitched tone. The

advantage of the Sovereign's threshold tonal reproductive range is that the tone of

the threshold also changes. After the target signal is heard, the threshold "hum,"

returns in a pitch similar to the pitch of the signal. When the target signal is

blanked (or nulls out) due to some positive discrimination, the threshold returns

again in the higher or lower pitch of the target's conductivity. The advantages of

Pitch Hold should become apparent in ground that is considered fairly clean and

also works very smoothly over salt wet sand.

The Iron Mask feature is an overall ferrous discrimination control, which can be

adjusted to reject a large amount of ferrous targets at one time. An increased level

of Iron Mask will reject more ferrous targets while a reduced level will accept more

ferrous targets - ideal for relic hunting.

Some improved Iron Mask functions have been implemented:

1. The new Iron mask has values in 0 - 31 range to match the range of Ferrous

numbers.

2. The Iron mask screen has been modified to show "FER" inside the slider and to

show "AM" when the All Metal is enabled.

In Figure 1 (below) the new numbered Iron mask is seen while the old system is

shown directly beneath it.

All Metal - is the term used to describe a clear discrimination pattern - that is

accepting ALL targets whether ferrous or non-ferrous. To select All Metal press the

shift button next to the AM icon to reduce Iron Mask and clear the discrimination

pattern. Bear in mind that A.M. might be "noisy" on certain soils that might have

high levels of mineralization in them.

Gain - the Factory preset has been changed to 8, a higher setting from which it

used to be set at in both former Explorer models (used to be 5). This might become

noticeable right away as certain signals might be more pronounced with better,

faster, louder and sharper signals when compared to an older Explorer ll model.

Gain actually controls the amplification of target responses in respect to the

strength of the original signal. The theory is, with a high setting (8) even weak

target responses will initially be, easier to hear which could equate to more finds,

especially small low-conductive ones at the end of a day's detecting or increased

deeper finds from sites considered to be "worked out". On a modern site such as a

concert field looking for recent losses one could use a lower Gain setting coupled

with a Low sensitivity setting to deliberately look for surface/shallow finds as one

would not require the extra sensitivity to search for losses from a day or so ago.

Sensitivity - following along from an increased Factory Gain setting there is also a

noticeable increase to the Factory preset Sensitivity level - this is now set to 22 - an

increase of six sensitivity increments from a lower sixteen. As a result of these two

changes of (i) an increased sensitivity and (ii) gain setting it will appear the Explorer

SE is more powerful on turn-on compared to the older models. These Settings have

been increased at the factory and those settings were always present and

adjustable. There might be a trade-off from using higher settings and this could

result in unwanted noise and more ground signals. If this occurs simply lower the

settings via the Main Menu. However, bear in mind that, Semi-Auto Sensitivity can

be a good friend and will continuously monitor the environmental conditions and

will automatically adjust the detector's sensitivity as close as possible to the last

manually specified level of sensitivity - especially useful in those often difficult sites

with ever-changing ground conditions. Manual Sensitivity on the other hand

would be better suited to a trashy site or, where a very slow sweep is required or on

a beach.

Depth Indication - is improved over that of Explorer ll and now updates visible

information at the end of each detection and, updates in the new and improved

Pinpoint Mode also.

The clear portion of the depth indicator represents the approximate distance of a

target below the coil based on a single coin from 0 to 30cms. Try to think of the

clear area as the amount of soil you will have to remove to get down to the target.

Digital Fer Cond - as per the depth indicator, Fer and Cond now display and update

information on screen while in the Pinpoint Mode. Previously, this was not possible

and is one of the most significant changes to the Explorer SE software.

The four numbers in the Digital screen display both the ferrous and conductive

properties as perceived by the Explorer SE in magnetic response for ferrous and

conductive response for non-ferrous.

Fer or Ferrous shows from 0 - 31 the ferrous resemblance of targets while Cond

shows from 0 - 31 the non-ferrous conductivity properties of targets. So a display of

Fer 07 Cond 25 would indicate Fer 07 as being of a low ferrous nature (non iron

probability) and Cond 25 would show a high conductivity (copper/brass/silver) and

the target might produce a U.K. copper ID. Displays of Fer 04 Cond 28 could

indicate a U.S. dime while Fer 08 Cond 10 might indicate a gold coin.

Threshold - has been changed to a Factory Preset setting of 16. It has also been

improved so that finer adjustments may be made to it, especially at the lower end

so that one can set it to a very low level but that it shall still be audible whereas on

the previous models it may have been too quiet or may have gone silent. A silent

or non-existent threshold is not recommended as a small depth loss can actually

occur as one may not hear a very small target, nor should it be too loud that one

could not distinguish a false noise from a target response. As always, the threshold
