Ferrous-Coin, good target, no audio?

I haven't yet dug a coin based just on the screen with no sound. I get a lot of activity in the coin area on the 2D screen without sound so I am a bit reluctant to dig them yet (AND my pinpointer is broke so will wait till I get another one).
But, I posted this test in another thread. You might want to watch this and see what ferrous coin can do, as far as potential coin signals on iron. This is an out of ground test, but at least it warrants further investigation. I haven't dug any iron yet that read as coins in the ground though!

I have dug quite a few coins with no audio. This has happened when the threshold nulls due to iron but the coin target was visible still on the screen. Although this is great, it has caused me to need to change my hunting habits quite a bit. I was primarily an ear-hunter before the CTX but now I find that I have to look at the screen much more to see if there is a good target each time the detector nulls. Hope this helps -Marc
I typically hunt by ear. And honestly, I can't imagine trying to metal detect while continually looking at the screen. Life is simply too short! But during the test process, I started out digging everything, just to see what makes the CTX 3030 tick. In that process, I dug a lot of holes where there was no audio, but floating images on the display. Those floating images that look like a meteor shower...... usually ended up being broken down iron with rust leaching into the ground. In my opinion, if you're using Ferrous -Coin separation, hunting by ear works well. Much of that will depend on how you set your tones for the various "bins". If while making a sweep, you hear the slightest audio response that "sounds good enough to grab your attention", take your time to work around the spot from various directions. As you do so, listen for the tones and watch the target trace. The TID numbers may be skewed if there is an abundance of iron nearby. And if that iron is much larger than the "coin" signal, it could overwhelm the coin's audio response during the majority of the sweeps. But if you occassionally catch that coin tone and see a solid image in the proper location on the display, dig it up. More times than not there has been a coin hiding in amongst the trash. As a reminder, when you are repeatedly sweeping over the same area, occassionally pull the trigger to refresh the screen. HH Randy
i am not a screen watcher either but seems as more time with this machine more time looking at the screen, yes the meteor show has not produced anything good yet, neither a full red hot dot that fills the cross hairs 99% of the time, anyway guess time and more testing is needed good excuse to go detecting 
will try digging a few more noiseless screen targets or try get them to make a sound.

Marc - Very interesting. I hadn't heard of anyone digging coins without audio yet. Knew it was possible judging by the manual. How deep were the coins? Any specifics outside of what you said? I'm curious what to look for, for as I said, I get a lot of action in the upper 1/3 or so of the screen with no audio. I'm looking for target trace to break up good on non coins. But just a theory.
Digger - Good description regarding "meteor shower"! LOL. I noticed with bottle caps that the targets "splatter" like in my bottlecap video thread. I to think that is a great feature. I'll listen closer for those tones with more solid images as you say. Thx.

I have not yet tried the ground coin setting. I do plan on testing it out but my ground iron mineralization is not terrible. With the E-Trac I could easily get 9" on coins so I don't think the ground is that bad.
But thanks for the reminder, I will eventually test it out - it's on my list ;-) .
