No threshold signal, yet still get a coin...?????

[NebTrac]

Mike-In brought up a good point and a question I've had since I've started learning the E-Trac. I've had places, as I'm sure you've all had, where I will have no threshold signal for maybe 4 feet or more. If I slow way down and go 1/2" movements I still get a slight threshold. I'll let it stop, move a millemeter and out it goes again. I hit quick mask and listen to 20 different 5th graders warming up their orchestra!!

I've been using Andy's old coin program, but what's you guys' experience. Will a solid signal still come through if there were a wheat or silver there during the nulling? I've put in 25 hours on this machine in the last 6 days and am determined to learn. Thank goodness for the coins I have found, the E-Trac has been nice to me there!!!

Thanks,

NebTrac

That is what has been happening for me even though I guess there are believers in both camps. When I get in the null areas I sweep "real, real" slow. I mean so slow it takes around 10 to 15 seconds to make one pass. I used to back the sensitivity way down when I hit these spots but amazingly I'm doing better with it cranked to 30. Maybe it's a fluke of the site but I'm enjoying the rewards! Mike

I believe the good signals will still come through. that is what makes the Etrac so special. I also think that is why when you re-visit spots you may have done with other detectors, you get more finds. I don't think you need to hear the threshold again to hear a good target.

I think the reason for somany finds from punded out parks is just that. I beleave we dont have some of the masking that other detectors have. What i have done is marked an area with my Delrome PN40. Then go back with a small coil to work the nulls.

There is no doubt the E-Trac does hit a lot of coins in a dead continual loss of threshold as I have hundreds of them to prove it.I posted a long while back that new owners might be ahead to hunt a few hours without an audible threshold so they would not be thrown off by the nulling in many sites.I think a lot of the nulls are caused by mineral content changes in the soil matrix rather than just disc-ed out targets.The shorter nulls are more prone to be rejected targets
It is best to slow down some in nulled out areas but if you moved slow enough to maintain a steady threshold in many areas you would fall asleep from inactivity
The E-Trac is in a league by itself when it comes to separating the good from the bad targets at faster than a snails pace.The Explorers are about as good but require a ultra slow sweep speed to get the same level of separation in my experience,Ray.

Ray. I laughed so hard at that because I know exactly what your talking about. I think you hit the nail on the head because at this old school that is long gone I hit an area where my recommended Sens. went down to like 10 or less. No power lines around. I really really think I was where they kept the coal for the boilers.

run a manual sense of 22 or higher and use long tones or smooth.
youll be amazed at what the et will do in the nulls then.
i was in a dead null but got a penny sig. from about 7 inches down and when i found the target it was a small metal match box that had rusted into a large clump of rust. i hit on my digger and it broke open and was hollow and then a 1942 wheat fell out of it.
i posted picks last year of it so people would beleave me.

Next time your in one of these constant null patches try an open screen on Ferrous two-tone. Ignore the low grunts and keep and ear out for a high tone and slow swing......this works really well in iron patches because it's not nulling anything making it less likley you will mask a good target with a null.

I've done very well with these settings outside old stables in cleaned out sites, i'm sure many other brand detectors have been tried and failed before me.

I'm a big fan of Andy's Coin pattern and use that in almost every other situation.

Cheers,
Greg

Until someone using machines other than the E Trac have the opportunity to see it, or experience it while running one, they will not believe it. I've found a bunch of good targets just moving 1/2" back and forth or less above a target in all kinds of nulling trash and would isolate that particular target to dig all of the scrap up and the good target be there. One particular I'll always remember, a 12-13 TID and null in all but in a precise spot. I started digging and out pops aluminum, iron, rusted screws (just a ball of rust by then) and below it at a depth I'll not mention is a nickel that was below all that junk. I was a believer at that moment!

Hey gregliss, when you say open screen do you mean all metal or excepting 27 and up?

 

[Ray-Mo.]

You have to run all metal 100% open screen for best results and to hear the low iron grunts.It is a super way to relic hunt at older sites without much modern trash of the aluminum variety,Ray.

 

[gregliss]

Hey gregliss, when you say open screen do you mean all metal or excepting 27 and up?

I should have given more detail:

It's not quite a full white screen I run, I keep the top half of Andy's Coin pattern, its a small strip across the top that stops around the CO30-CO35 mark (not sure off the top of my head) to allow large silver. Iron can false across the top of the screen so this stops most of that.

But beside that strip at the top the rest of the screen is white. Anything in the iron region will just give a low grunt, anything in the non-ferrous region (top half) will give a high tone.

You can still refer to the ID to see if you want to dig it or not, but when you're in iron the ID numbers are very unreliable.

Hope that helps.

Thanks a lot gregliss and Ray-MO. I will have to try that at some of my deep woods hunted out site's!
