Highly mineralised soil

[pauwil]

Hi Guys

I have a question, what is the best way to combat highly mineralised soil with the CTX 3030?

i was at a dig on sunday past couldnt find a thing which i put down to the soil, where other machines coped and we are going back this Sunday, so any ideas guys?

Thanks in Advance

Did you try ground balancing?

[Flossyrockstar]

Or the six inch coil could make a difference.

Hi trash filter

[ARGONAUTE]

Put it into GP-X mode

[pauwil]

Yes it was ground cancelled, ground balanced, Hi trash filter on and deep on fast off on my coin program and on my silver program i had ground coin on but fast and deep off.

as i'm new to this forum and the CTX, i was reading some older threads and am i correct in saying that turning up the sensitivity and switching on fast and deep will help on mineralised ground?

im sure id posted on this thread ? i must be losing my mind

No machine went very deep on this site Paul. Soil was black and highly mineralised. Solas switched from his T2 to the Etrac and said he was getting better depth.

[pauwil]

How do, young man? I'll see you on Sunday

[Tombs]

if its really bad i would go fast on deep on long tone's ferrous coin....maybe ground coin test that on a target, 50CO tones open screen and dig anything that's not a high tone.
in bad ground deep targets sound like iron but every now and then give a low or mid tone
good luck

Thanks for your replies, Tombs, i think try that see what it's like.

Hi Paul,

You're in Scotland right?
The soil is notoriously bad there correct?
That would be a case of YES, do use the Ground Balance feature of the CTX 3030.
Leave the detector in Auto Sens
Select the Ground Coin option
Select Fast on
Select one tone
Create some iron masking on the bottom of the screen - Edit Mode and bring up the Ferrous line to 31
Do not work in all metal bt you can use it to check signals in the case of a jumpy cursor / jumpy ID's but GC should help steady all of that?

Good Hunting on Sunday...I hope to be out as well?

Don't bother with anything "fancy" and allow the machine to to work for you.

Great advise Des.

Interesting, I tried a TTF today for the same problem with some interesting results but never thought of a single tone, mmmmmhhm I'll give it a go tomorrow and see how it goes. Thanks Des

sounds a great set up that des is recommending -you just cant beat the advice of that type of knowledge - i think myself many make things far to confusing - when simple effective detecting is the best and most pleasurable - remember its the finds pouch that ultimately is the measure (if on productive fields)
By setting a minimum discrim as suggested and digging any good target signal as this program suggest is keeping things easy for the machine as well as the user.
yes your going to get iron creep past the discrim on the larger stuff - but its a trade off - and you can start to get a feel with what large iron is on the id.
personally i think this advice des has given is the secret to its use.
infact i cant see ...a better program for inland detecting.
i think most uk detectorists should try this set up and would be surprised what they get with it.

Whats ttf?

[jon_jn]

two tone ferrous.

[gazzaj]

Ahhh ,thank you.

Kyle,

That was a one-off recommendation to see if [I could "guess" what might be the best settings for that site he was going back to]
I wouldn't set-up my CTX like that the majority of the time but, to help combat the effects of ground mineralisation reducing the amount of signal Tones can help produce effective signalling.

Most of the time I use:
Combined
Switch between FC and High Trash
Target Trace
Normal Pinpoint
A few disc programmes I made for my sites done on XChang2..."Minimal Disc", Irony Farmland" etc

Good Hunting
