    My CTX 3030 loves nails

    Hi everyone,
    I've had my CTX for a couple of years now and really like it, but can't seem to avoid nails. I've tried changing all kinds of settings, watched tons of videos and read the book by Andy a few times and still can't seem to solve this problem. No matter what I changed, it still seems to pick up on nails both older square nails and newer nails as well. Do any of you know of a solution to this problem, they seem to ring with a high pitch and fools me 9 times out of 10. This happens even when I'm in the stock Silver mode. I'm no expert with this machine and was wondering if anyone had any good tips to fix this ? At the same time I don't want to discriminate out too much. Thanks for any input or solutions.

    What readings are you getting? Nails can many times read 47 on the conductive side, just like quarters, but, they should read in the 30's on the ferrous side, giving you indication that it's not a good target. Now deep rusty iron can give you a chirp too good to resist, but, that shouldn't happen too often.

    And bent rusty nails come in as good targets too.

    I get some of the older hand forged nails as good targets, however in my book the 18th century nails ARE good! I keep them.

    I use an etrac and mainly coin hunt in multi conductive tones, and yeah nails can give a high tone but it will be a less consistent sounding tone than a good target would make.

    Some things that help me are.. Lowering the sensitivity so there are less iron falsing sounds. A good target will have a much more consistent/repeating sounding signal while sweeping over it compared to the blips and inconsistent sounding sweeps that an iron false will give off.

    Then a big thing that helps is being able to get that consistent/repeating signal from 2 different directions, like an X, and the signals should repeat in pretty much the exact same spot on the ground from both directions(the middle of the X). If you can only pick up the signal from one direction, or it moves when you check the 2nd direction than its most likely iron. The pinpoint feature can help in that regard too, the spot it pinpoints should be pretty exact to the spot you're getting the signal from on a good target, where as a bad target could pinpoint a little off of where the signal is coming from.

    Some items will still trick us quite a bit though, like bent nails or nails that are straight up and down in the ground, or other iron items that have a shape like a coin. They can give good sounding signals.
    That's all I can think of right now, but these methods definitely help me while hunting.

    My Tesoro Cibola jst scored a biggie in a nail and trash pit. It's a beep and go. I do keep rose head nails and preserve them and some of the CW nails from the huts. Out of the burned huts they look great.

    I always dig when the number is 12 and the other varies. Usually it's in the 40's, sometimes in the 30's and once in a great while in the 20's.

    Good info/tips! I also have an e-trac and never had this problem with that..... At least not to this extent. The e-trac took me about 1 hunting season to figure it out. The CTX is going on my 3rd season and it's still fooling me.

    Great post here! I also like to use the target trace feature. If you get lots of "iron splatter" and not a good solid target that is a good sign.

    Slowing down and hitting it from several angles helps me more than anything.

    This is true...mine loves tiny steel screws down deep sometime, but only when its the ground. There are so many factors to what could be doing it I guess. I remember my ATP doing goofy stuff sometimes...still dig them thou.

    Old thread but do you run disc screen and then switch to see the iron in the lower right corner? (and hear low tone)
    If you have lines greyed out at lower bottom on open screen you’ll get a threshold silence and sometimes a target sound. It is intended to ignore bobbypins. I was experimenting the other day digging weak threshold silencers and it was always a deep bobbypin if it kept silent as I dug towards it. Something else would bring on a tone eventually. Naw didn’t find any deep gold rings...

    I tend to start without much discrimination and when I hear a nice tone will switch over to my other screen with more discrimination. I used the e-trac for so long that I preferred digging based upon sound versus what the screen shows and had a lot of success. Seems like with my CTX 3030 that I'll get a nice high tone, then look at the screen and it will usually be in the coin area (upper right) but then when I pinpoint it drops more towards the bottom right of the screen. I hate passing up on them because I'd hate to miss a nice target but maybe that's my problem. Trust the detector screen and not the sound as much?
