Hello,
the Minelab SE is a very deep seeking machine with excellent object identification. However it is not easy to master. Here are some settings I can recommend:
From the menue go into Advanced settings
Display Smart Smart Display
SELECT. Clear the screen and then scroll down and reject NAILS only.
( This gives you a small area blacked out in top left corner)
AUDIO.
RESPONSE.....................Normal
>
AUDIO.......Sounds.........Ferrous AUDIO
AUDIO.......TH vol....... ........... 10
AUDIO.......Variability. ....... ...... 6
AUDIO.......Limits............. 6
>
AUDIO.......Volume.........10 AUDIO-Band ....... ......... 10
AUDIO.......Gain...............8 AUDIO-Gain ....... ............... 8
>
OPTIONS....Recovery......Deep.. OPTIONEN .... ...... Recovery Deep .. On
OPTIONS....Recovery......Fast.... OPTIONEN .... ...... Fast Recovery .... Off
( this can be reversed if in particularly noisy conditions) It is also possible to run with both these off but never both on together.
>
SENSITIVITY....Function.....Manual...(for maximum depth)
SENSITIVITY....Value.........1 - 32......Fix to maintain stability
It is a good idea to start off with manual threshold set in the low twenties initially then raise or lower to suit.
Auto Sensitivity can be used if preferred but set at maximum so that the Explorer can search the whole range from 1 - 32.
THRESHOLD TONE ....... Set at a level to suit ( usually just audible)
>
IRON MASK....... If preferred Iron Mask can be used instead of the nails setting above.....Press the Iron mask button and set the value to suit the level you require.
I normally set mine on 28 - 29 on the SE which gives a thin narrow black line down the left hand side of the screen.
The thinner the black line the more Iron you will detect but the thicker the line the more good stuff you may discrim out.
You can switch between the IRON MASK setting and NAILS by simply hitting the Iron Mask button three times.
This programme does not use Variable tones which will help in the learning process because a single tone is less confusing.
On detecting a metallic target a good repeatable signal with a solid tone will be heard.
You will also have to rely on the cross hair position to help in deciding what type of signal you have.
In general most good non ferrous metals show in the right 2/3rds of the screen, top or bottom.
Signals bouncing around with the cross hair tending to show to the left are generally Iron.
