No tones on deep targets

[sitedude]

Hi guys,

Still getting used to my 3030. I was at an old school not long ago and found a 1913 merc dime. I could see a blip of red on the screen in the dime range and it was down about 5-6 inches.

I read Andy's book and started a test garden today. I planted a quarter at 9 inches flat into the hole. The 3030 would get sporadic readings from 10:31 - 11:35 - 12:47 but never a tone on the machine at all. I could never get a steady reading and if I was out digging somewhere most likely I would skip over this as there are no tones. Is there some setting I am missing to hear this tone, a lot of people say they use the 3030 and never really have to look at the screen, just rely on tones which I always thought to be true until that dime I dug up with no tone and tonight when I couldn't get it to hit on it.

Even at 7 inches I hardly got any tones, maybe a faint one after swinging and doing 360's around the hole. The ID number was very off as well at 7 inches. It makes me wonder how many good targets I am actually missing and what I can do to correct this.

If you found a 1913 Merc you'd better get it appraised....they didn't start making them til 1916...
Where is your Gain set? VOLUME limit?

Not an expert but I'm guessing you're using an auto sensitivity setting. In a vacuum this may work but what I've found after years of explorer use and now the 3030, always use manual sensitivity and let your ear tell you when to turn up or back down.

Problem no one seems to acknowledge is where there is EMI it's going to dial down based on that not soil conditions.

Example is a place I test my machines the EMI is off the chart. I can run manual sensitivity from 24-28 depending on the day.

If you try running auto +3 it suggests 13 sensitivity

If I go with manual 26 and detector is working like my first CTX 3030, I can get a 14" Minnie ball. If you let the detector decide, it kills depth, lucky if you find anything.

I never hear even CTX experts talk about this

Probably seen my results before, but it shows how great the decrease in sensitivity becomes using AUTO sensitivity vs. MANUAL sensitivity

Ha ya I meant 1931, I have the volume gain turned to the max at the moment.

Shockingly I have not seen this graph, very interesting! i do usually run at Auto +3 but Manual 25 looks very enticing, I am going to have to try this today.

Thanks Jtalley! I am going to forget using auto for now I really think this is my main issue, I was always worried about it falsing in manual but it seems like I have missed so many possible targets ignoring manual sensitivity.

 

[sitedude]

Thank you all for your help! This is great information that is being put to use later today

Do you guys think separation would somehow affect it as well from making tones?

Also is there some technique for identifying possible good deep targets? I notice the deep targets like to move all over the screen on the scale never really giving a true reading of what it could be.

 

[amberjack]

are the test graphs from in the wild targets ?

thanks.

Referring to this graph what was the sensitivity on the screen while using A+3?

Please keep in mind that graph is for an AIR TEST, not a ground test of a wild target. I always recommend the highest sens level you can run with stability, but I encourage you to try some personal testing. NExt time you go hunting, put your CTX in whichever manual sens level you want. When you get a target, switch over to auto+3 and see if you can still find the target. To date, I have found nothing in manual that I didn't also find in auto. Not to say that I haven't missed some ultra deep over the years, anything is possible.

Do your own testing, make your own programs. Never rely blindly on what anyone else claims (including me! LOL)

I wonder if the ground in South Carolina is a factor into my lack of finding deep targets. Here we have a lot of sand / clay in our yards. Anyone hunt these conditions?

Problem no one seems to acknowledge is where there is EMI it's going to dial down based on that not soil conditions. This is true emi well dial down the detectors #s but ground noise soil conditions well also dial it down . Now you can override that by going to manual but the more sensitivity you use over what the machine calls for the more noise you well hear so you have to pick what you are comfortable with . Auto seams to be very conservatory it runs very smooth at these settings as it should but your not getting all you can from the machine at these settings .
Noise cancel and sensitivity are connected as one if you have low sensitivity #s you have lots of noise the machine is trying to get rid of . If your auto #s are high say 25 you have less noise for the machine to get rid of .

Running at high manual settings will make the machine more sparky more noise but when you sweep these signals they will not repeat like a coin signal another words there inconsistent . So if your going to overdrive the detector you will produce more inconsistent signals.






Sensitivity controls the detector’s response to received signals. These signals can include desirable signals from nearby metal, as well as undesirable signals from electronic noise, and noise due to ground response. Increasing the sensitivity level may make targets more detectable but may also increase detector noise due to these noise influence.

Try this sometime if you have a good spot that quit producing go during a power outage and see what happens .sube

I have a number of spot I just WISH I could hit during a power outage. Unfortunately those always seem to happen during horrible weather and never last very long.

Wow Sube, I was looking for the 'like button' on that response, lol! Last outing I noticed quite a difference between manual and auto. Too early to say my results were better, but the machine definitely was hotter.

 

[psyvad]

Thanks for posting the charts. I'm just getting started with the CTX and thought Auto+3 would get the maximum depth!

 

[LawrencetheMDer]

Great graphs - in this case worth a 1,000 words. I'm switching over to Manual tomorrow.

Unless you've already tried this, go into Response and click on Pitch Hold. Andy stressed this point at the Gettysburg bootcamp and said that some deep targets that do not produce any audio can still cause a change in the threshold. In my test garden this proved to be correct. This change in threshold also made me slow down over the targets and be able to "bring out" some actual audio. Of course this is my test garden and I am aware of where the targets are even if I can't here them. Out in the field utilizing this pitch may very well drive you batty because it's a bit noisy but I'm pretty sure it can give you the ability to uncover deep targets that you can't normally here. I plan on using it from here on out

 

[amberjack]

each to their own I guess that's why detectors have features and as Jason said do your own testing and its solid advice I do my own testing and use what works best for me..

so not here to pass judgement on how others detect its "what ever works" right

only advice I have is have fun testing

Thid is a thread of discussion every couple months it seems, I am one who regularly switches between manual and auto on deep targets. And I have regularly had targets that sound great in manual(as high as my ground and conditions permit) then when I flip to auto the target disappears or becomes a target I would not look twice at. Everyone will have their method and experience but I am of the opinion with out a doubt you are missing deep stuff running auto in a lot of areas
