Hi Alan, Ferrous is 1 to 35, Conductive is 1 to 50

@UB40, think it is in Conductive mode, thats a bit embarrassing as I don't know :D

It is in factory default, coin hunt mode, with just one bar of descrimination, only other changed setting there is ID trail in on


I am just collating the data and will post some pictures of the ID zones

Hello Dave,
interesting results..re:conductive/ferrous....what setting was it in?The tones all seemed quite "high" so would that be ferrous?As stated that even though there was a slight dip in tone the numbers all seem to be tightly grouped for a broad range of good targets.Are these numbers/tones consistant with buried items?Are the results comparable to the Etrac in terms of numbers/tones or is the Ctx more easy/difficult to understand?

thanks

Hi Clint, I am currently running a combined tones pattern, high tone for non ferrous going lower towards the foil zone, and a very low tone there and the same low tone for iron that is not discriminated out. I am still digging lots of iffy signals just to be sure , still learning. I have found very small fragments of scrap copper, air gun pellets, and foil so know I am not missing anything small, but I have a lot to learn with these between iron. Most of my digging since getting the machine has all been relatively near the surface down to about 6 inches, hoping for some more depth in the winter on my pasture. I went from an Explorer, and found the settings and tones it made quite similar. Re the real world detecting on targets in the ground I haven't personally found the bronze/Silver coins to read much different to the air tests. But have yet to find a hammy with it, my own sites have none on so only get to look for them on club digs.

Thats why we only use a bare minimum of iron discrim. ::g

Pete
Hi Pete, thanks for the tip, must admit I have been using quite a bit of discrimination lately, more than shown in this thread, I have pulled a couple of bronze items out the same hole as an iron nail and agree the signal was lower down, jumping between the two signal types as well. I will knock the level down from now on to see what effect it has, but everything I have dug low down in signal has always just been iron, the only one that really caught me out last month was an air test on another hammered coin that was as far to the left as the display goes, where all the foil shows up, so I won't stop digging those signals lol.

I really like the machine though, easier to swing all day over the explorer, the GPS is brilliant, but I would like a load more options in the exchange software, mainly to import my older GPS logged finds and be able to sort the icons on the left in to a different order.

I hope so Pete, best to keep it basic to start with as some struggle with computers :))

Forgot to mention, where's the cover for the control box :-/ :-/ :-/ :-/ :-/ :-/ :-/ :-/

There must be some demand now ? Heard any news on them ?

I have only seen ones in the US and AUS

Hi Guys
I'm very interested in the 3030,but have a doubt about its ability to find small gold items.
ie small gold links small hammered maybe

Hi, lead for me very much depends on its size and thickness, it comes in anywhere between where that half hammy penny in shown though to the bottom end of those bronze targets, one of my permissions is full of lead hem weights, and quite offen I can not tell them from a coin, but then I mainly dig on sound rather than display, I only look at the display to confirm a dodgy signal is iron, as this shows up rearly well, with the false iron leach signal shooting down to the base line from the top right zone

Thanks for that. As a potential buyer for the 3030 I found it most interesting. Are these figures roughly the same for the e trac? ::g

I am not sure but there is an emulator for the etrac so that might help with typical air test results

hi guys basically a question for etrac users that have gone over to the ctx 3030 , what in your opinions does the ctx do better than the etrac and does it go deeper than the etrac ,as i have heard conflicting stories that it is not as deep . only asking as i am thinking about changing ,as the missus has given me the go ahead if i want :D

with the etrac in my opinion you have to search in conduct for the low tones with the ctx you can change the tones to suit you .so for me that alone is worth it
