According to how high your sensitivity is running in auto

[LabradorBob]

When do you consider it time to go to High trash in the expert settings?

Say - Sensitivity is at 16 in auto,is this a high trash area?

Where does the sensitivity have to be for you to go to High trash?

Looking for different opinions.

I use high trash when I start getting several targets per swing with some falseing.Also if I get a lot of nulls from disced out targets as in lots of iron and nails.Fast on for the same reasons....

 

[NebTrac]

I leave mine on high trash most all the time. It seems I can walk 30 yards and hear the Th tone all the time, then hit a spot and get a lot of nulls. Now the Ground Neutral or Difficult option I change. If my suggested goes below 20 I switch to difficult. Most of the time I run Auto +3 and my sens. usually runs 23-25. I have had it go up to about 29 in certain areas.

I think the sens. is going down from say 20's to the teens means the e-trac is sensing the ground mineralization,so it tunes down the sens. to comp. for the ground min.IMO,so as far as high trash i try to use low unless i cant the less filtering the better,IMO

Same as Ray-mo for me. Also, I will lower the gain a notch or two in high trash. Some areas I swing on will have more than 10 targets per swing and virtually zero threshold....

.......yeah, I always took a view of having a cutoff of 15 on the sensitivity. The setting to use in this case would be the Ground setting.
I did 15 or below - Difficult, 16 or above - Neutral.
Due to another UK forum member doing some experimentation, I know keep mine on Difficult as default.
He had a large UK solid silver coin called a Crown. It hardly picked up the coin when in Neutral but blasted through in Difficult !!
Mine now stays on !!!

I did some reading up last night on the Trash setting.
I don't think it will effect me as it only alters the way the ETrac displays the target ID's, not the audio......I think!!!

i think your referring to the neutral or difficult setting when looking at the sens level. At least that's what I read in the book

Question, Does this matter if you are in a disc pattern you have loaded, or in Quick mask using TTF, with a bit of disc. Also, kind of not on the same subject, sorry, I just ordered an ETrac, do you guys using TTF in the iron laden country side, have a pattern already constructed to load for this type of hunt or do you just use Quick Mask and put in a bit of disc??? In which ever case, how much do you black out just to git rid of nails. Ray mentioned he changed when he gets several targets per swing and some falsing. Will I be able to discern, after time with the machine, a false signal from a good?
Im really looking forward to learning the sounds, thats what I have wanted for a long time. Ok , sorry I got off subject.

trash density high will make the detector sound off on an accepted target even if a rejected target's signal is stronger on low the strongest target signal will be heard........

 

[EtracTom-AdirondacksNY]

Grouser's response is correct so I leave trash set to high all the time if coin hunting unless say your relic hunting and looking for iron like objects.
Ground difficult all the time unless when in auto if the sensitivity goes above 22 like NEBTRAC's area does then you can run in Normal if under 22 use Difficult. My area is 17-21 in auto+3.
Also for sandy areas run Ground normal like at a beach or plowed field it's right there in Andy's book why you do all these settings and set them this way, they were the testers before the Etrac was released.

 

[grouser]

a side note,,, I was in a spot where auto +3 was running at 7,,,,,what the heck does that tell ya about my ground !!!!! No, I'm asking what DOES that mean ???? i went to manual and ran much higher but the area was just littered with square nails and I did not have much time there,,,

 

[EtracTom-AdirondacksNY]

Means lots of mineralization from all that rust in the ground and the Etrac said that was the best sensitivity for it to see and operate in that environment. It's like the high beams in fog thing, it works better with low beams in all the fog. When you come out of it (that area) the sensitivity should ramp up higher as the detector see's the ground is better with the ground reference channel so pushes it back up for you Automatically and this is how AUTO works.

The machine has 4 channels that it uses to compare what it sees in the ground to give you that sensitivity setting. One is for ground reference and the other 3 are for low med and high range it gives the best average of all three for the sens. setting in comparison to the ground reading in Auto mode.

Manual mode over rides this and your forcing the machine to run those 3 channels at the same sensitivity making it hot so to speak It may not be the best in all spots to run smoothly just like the fog analogy.

age old question I guess,,, someone said a tech from ML told him he would NEVER run in manual because the ET does somethings in auto that makes it work so well, but others like to run it hot,,,

I imagine that could be true under certain conditions (e.g. - high trash). But I have compared signals on 7" or 8" coins in my 1% iron mineralized soil and e.g. - A coin at that depth in manual 30 rings ok, but when I drop it down to 25 - 27 +3, it often won't pick it up! The 30 in manual is 3X30, the 27+3 is only on one channel, I believe the other two are lower.

It seems like 9" or 10" might be the limit in my soil on a copper/zinc coin judging by the hits, with manual at 30. What does that tell you about how that 1% iron mineralization affects deeper targets? (or is that normal?)
My other single frequency machines had problems in this mild soil due to the iron mineralization I believe. (at depth greater than 6").

I was switching to neutral when auto was above 25 but it seems like most do it lower, so I will give that a try

I normally have high trash on but if when the responses in a swing are low I switch
