Forget Programs...

If you want to get an idea what a detector is really listening to, just set a prospecting machine in 0 iron mask with high sens.
Then run it over a trashy site.

The noise and volume changes just don't stop.

First discriminator out there is sensitivity, because your detector is generally pumping out the same power into the ground.
You tune your detector to notify when the received signal overruns a certain threshold.

It sometimes amazes me how people tune a detector all things considered. Threshold, Sens, Disc, Sweep speed, etc. etc.
One guys detector runs like a veritable machine gun.
The other tunes his detector to virtually run silent and alert him to the good stuff.

Thing is, most detectors put out the same power into the ground all of the time. So when sweeping over missed targets.
Who actually missed it? The detector or the operator?

I can see how a discrimination pattern can miss coins. I run my CTX in ground coin combined mode. I have my tone ID set around the nickel range 13 conductive. What I noticed when running the discrimination pattern is that the machine will null every other sweep most of the time. When I switch to an open pattern it hits every time. Also pull tabs usually will not do this so I know it

Mike I totally agree with you. With the ctx you don't need any discrimination at all. It's a super fast machine and compared to detectors like the V3i it's super quiet in all modes

Recognizing that we all have personal preferences (and likely old habits), I encourage everyone to try different combinations until they find the combination that works best for them, in their sites. Different Separation modes, different Audio profiles and different levels of discrimination. With that said, it is important to note that the CTX 3030 (as with most notch discrimination detectors) detects every target, regardless of the discrimination settings. The only difference between how the CTX 3030 reacts to an accepted target, compared to that of a rejected target, is in the audio response. For accepted targets, the CTX 3030 provides a visual target indication, and replaces the Threshold with an audio tone whose pitch is determined through your programming. On rejected targets, the CTX 3030 still detects them, as confirmed by their appearance on the visual display. But instead of providing an audio tone, rejected targets simply null out the Threshold. As such, the difference between hearing a tone for every target and letting your ears sort them out, compared to hearing a tone only on accepted targets and no-tone (nulling) on rejected targets, is simply a matter of personal preference. I have specific sites that I prefer one over the other, and vice versa. But in the majority of the sites I hunt, I set up Pattern 1 with ample discrimination, Pattern 2 with minimal discrimination, and toggle between the two of them in an effort to better separate and identify each target.

I'll be honest here, when I'm in a COMPLETLY open screen the high tones from all the bits of rusty nails drives me nuts.

With an open screen I recommend using combine audio since the iron targets will have a lower response

I have to disagree. Anyone that's hunted with me at my spots knows how ridiculously trashy it is, and even with a lot of discrimination, it's a lot to listen to. My CTX is screaming on every swing, and I've tried to run it wide open with any disc, but it's too much. I really haven't run into a problem not finding silver running a lot of discrimination. I suppose it all depends on where we hunt, and the level of patience we each have for the constant noise in our ears. -Fin

Ronfin, it definitely is a personal choice whether you want to hear noise or not. Like yourself, I hunt in parks that are so trashy, if you go one foot you get some sort of signal. I am used to lots of chatter because when I had my Etrac, I ran in MANUAL 26-30 and it was super noisy, but also super sensitive. Prior to the Etrac, I had the Whites V3i which is a very noisy machine. So the noise of the CTX may be extreme for some, but for others like myself, I find it actually quiet even in really trashy sites.
