Short Video - "Signal Building" on Thunking with 7 inch Coin

[earthmansurfer]

This is interesting and seems to partially verify this target "lock on" or in this case more like "signal building" or "signal enhancing". Notice the auto sensitivity number was not moving. Now maybe behind the scenes there was a change in the sensitivity as there are 3 channels and we only see one number. Anyway, observe how no signal at first turns into a solid thunking sound.

Have any of your experienced similar things? Not necessarily with thunking. For example sometimes before videoing I check the signal and it's good, then a few seconds later I turn the video camera on and the signal is no longer good - goes in both directions! I OFTEN see this on coins that barely hit and then as I hover above them and "wiggle" the coin comes in much better. The E-Trac does this better than any machines I've used in the past.

Enjoy,

EMS , it doesn't look like your auto sens, is very high, and I can't read the manual side at all.This is why I use manual, except when in a very rocky area where the targets are shallow and or the minerals and EMI are very bad.
Yes I have had this happen too,both ways.

I love your Video's we are learning right there with you.

Djay - The manual side was being run in 30. And the Auto side was down to 16. Sorry, I didn't realize it wasn't that visible and I'll be sure to include that in the future. I was sort of shocked it was so low as it normally is at least in the mid 20's. It wasn't even trashy, guess it just needed time to adjust.

Thanks guys,
EMS

Thanks for another good video Albert, keep them coming. Thanks -- Randy

Now you know what it's like detecting here in my area's soil. In auto that is what I get and it takes a bit of running in auto for it to run better, maybe has to be sampling the soil some to get it's best highest sensitivity.

This is how I first discovered that thunking on objects as it appearsto be it is having a bit of difficulty reaching the extremes of it's depth in that sensitivity mode but you still get a pretty good numbers reading on the screen.

I generally get anywhere from 17-21 here in auto+3 which is what I run all the time. Last time with the ground starting to freeze up it was running at 15-16 in auto+3 so that is why your probably having a bit of difficulty getting it to hit good in auto now there as well as I see the snow so the ground must be freezing up some hence the lower auto sensitivity number.

I'm going to have to try manual here around 22-24-26 next year and see going over spots I've gone already if there are any deeper keepers I may have missed and how high I can run in manual depending on soil and coil without too much chatter and falsing.

When I had an Explorer2 that is what I couldn't come to grips with was all the chatter and falsing. I was running the sensitivity in semi-auto 16 factory and one day I found Minelabs website and saw how Desi Dune showed to set the sensitivity by lowering while swinging it over the ground till you got to a smooth sounding threshold sound and I ended up at about 10-11 then and it ran quiet and I started liking it and finding things. So I see in your soil you can go to 30 manual and it's still quiet so I would just run it there and keep it slow on the sweep speeds like your doing now and try to keep finding those elusive deepies Albert. Either they are there or they aren't.

i am a newbie to the etrac on its way but run a 705 and run manual sensitivity, turn it up till it starts falsing then back it off one or 2 numbers, noise cancel often to keep it smooth and trust the sweet sounds- etrac is the same? for some reason i want to set the detector up not the detector do it for me why i went with the etrac.

oh i must add the 705 has its own idiosyncrasies that i had to get used to and sure wouldn't have dug them when i 1st got it but now it finds coins at times with sounds a new user would not dig, so now to learn a new set of strange sounds

great video!

Albert,
I know this has been discussed on this forum before, but here is what happens many times to me. If I start hunting in auto +3 and I am getting 17 or 18 and then I switch to manual, say 25, and hunt for a little bit and then switch back to auto+3, it will be at 22or 23. I don't know if I would have just stayed in auto, if it would have made its way up to 22 or 23, not for sure. This happens in my little test garden, which is only 6'x6', so I don't think it is the ground conditions changing that much. I almost always hunt in manual so I guess I need to test it out in my test garden, start in auto+3 and leave it there for a while and see if it makes its way up.
You are making me think Albert, stop, it hurts, just kidding, keep it up.

yes I notice this too, when I turn my etrac on with auto +3 it always starts at 19 regardless what site I am on. but withing a few minutes it goes up to mid 20s. Now if I flip to manual 23-25 and flip back to auto the number is up in mid 20s a lot faster. No idea why but it does happen to me as well

 

[earthmansurfer]

Randy and Goes4Ever - Yep, I notice that too. When I switch from manual 30 to auto +3 (often I run it there to compare signals) it is often at 27 to 29. Well, in this video I was running auto in neutral, no + or -. The reason? Because of what you guys said. I wanted a lower sensitivity number as +3 was always coming in so high - then there was more of a difference between the auto and manual numbers and I could hear and see more in the test. Not sure in this video as I was running in manual for a while. Even then there is a difference in signal on an 8" coin in manual 30 and auto +3 at 29 - not always, but usually.

It had crossed my mind that if I was going to hunt in auto +3, to first start in manual 30 as it did seem always higher that way???

I missed the forum posts on this Randy as I'm pretty new with the E-Trac, so thanks for bringing it up. See, what comes around goes around... (Now you got me thinking...)

wow, manual 30.....i guess what Id take from that video is to leave it set on manual sens. I almost always have mine set to 24. even though i have had mine for a full season i still havent really tried a lot of different types of areas. i pretty much have hit old home sites that are really trashy. ive gotten pretty good at picking good coins out of really highly trash infested ground. maybe in a park i could crank the sens. up higher.

It show it perfectly! Nice video!
