This is my programme i use on the my local shingle beaches but on sand and also (land if using for coin hunting should be fine too) , except for coins that have a high FE content, they will need to be edited in if you want them .
This is the screen i use.

The top right is left clear because i have been told that silver rings sometimes appear there but i have not experienced that yet.
I leave a large amount of clear area because if you tighten it up to much you will miss good targets that are just inside the machine depth capabilities and also that just because in air tests a target may give a certain set of numbers it does not mean the same will happen in the ground, condition of the target or depth and ground conditions or position of the target will dictate the numbers.

This is the set of pixels that you will have to clear to have the screen i have.

Line 1.   numbers 41 to 50  clear
Line 2.   numbers 02 to 10  clear and 22 to 50 clear
Line 3.   numbers 02 to 11  clear and 19 to 50 clear
Line 4.   numbers 02 to 11  clear and 17 to 50 clear
Lines 5 to 16 all clear
Line 17. numbers 02 to 50  clear
Line 18. numbers 02 to 48  clear
Line 19. numbers 02 to 48  clear
Line 20. numbers 09 to 46  clear
Line 21. numbers 10 to 18  clear and 30 to 46 clear
Line 22. numbers 11 to 17  clear
Line 23. numbers 13 to 17  clear

The rest should be black out unless looking for iron targets though the lines from 20 should give you a inclination that a coin with iron may be there?

My settings are.

Sensitivity =  AUTO + 3
Manual level = 28 to 30
Threshold =  20 or to suite ( i use 20)
Volume limit = 30
Gain =    25 to 27
Response = Normal or to suite ( i use Normal)
Threshold pitch = 2
Tone i.d. = Number of tones = MULTI
Sounds = CONDUCT
Variability = 30
Limits = 30
Recovery = DEEP ON , FAST OFF
Trash density = LOW
Noise cancel = 1 to 3

This programme is not supposed to null out non ferrous trash as much as reduce the iron and some non ferrous trash.

If you come up with improvements on this for your coins and local area or countries then post here , this is mainly for British beaches or coin shooting on parks.
Deep pasture i would go for a screen with only the bottom 2 lines blacked out and go by sound and numbers.
I dont normally dig a target with a ferrous number of more than 16.

Good luck all.
