Deep On question

Well-known member
What it's purpose? It seems most experienced etrac users run high gain and recovery deep "OFF". If this is the best way to make deep finds, why did minelab even add the setting to the etrac??
Also, I read on minelab's website. It seems recovery deep "ON" makes a shallow target's signal weaker, a deeper target's signal stronger. I've been running high gain and recovery deep "OFF". I would like to hear from some of your experiences in the field with recovery deep "ON" and with what gain settings. Experiences where you made deep finds say 9 plus inches deep.
 
I know that the intended use was so that the deepest targets would respond as "loud" as shallow targets. I don't know what type of soil Minelab used in thier testing. I do know that in real life, using the deep = on feature causes many good targets to sound "junkier". I've never had a problem hearing any deep targets. It may have been one of those things that worked better in the lab than the field.
 
I am a fan of running my gain at 29 and deep OFF, been working great for 2 yrs for me. I agree with deep ON, signals do not sound as good and are a lot bouncier on numbers
 
On a handful of 8inch coins the crosshairs seems bouncier. I haven't noticed an audio difference down to 9" though. I run audio gain at 28.

I do think Minelab made a boo boo with this setting. I can't find posts where people say it actually helps them.
 
Hunting in this red clay where I live ( TN. ) deep on seems to help hunting CW relics better than high gain. I have tested this more than a few times. I set my gain at 24 and deep on BUT I go much slower with my sweeps because I know targets are there. If I am not in the highly mineralized red clay I set gain to 28 or29 deep off. In my opinion higher gain amplifies a deep signal better but in some cases deep on identifies a deep target better with a slower sweep speed. You may have to test in YOUR hunting area what works for you. I don't think Minelab made a mistake because most relic hunters use deep on. Just another whistle we can blow or bell we can shake. HH :minelab:
 
Thanks for the correction Hershey1. Interesting that you are talking relics which can often be bigger than coins. It is also interesting how you drop the gain with deep on. I have to try that one! Good idea. I do have a fair amount of iron mineralizaton.

Are there any coin hunters that found deep on working?

I think you have that wrong,,,, that is what GAIN does,,,,, DEEP ON runs information Thru additional filters and algorithms to better ID a deep target,,that's how I read it in the book anyhoo,,,,,HH
 
I also increase my gain and leave deep off. I feel both fast and deep don't give me as clear a signal. I know plenty of people will disagree with me on this. I keep as much off as i can with as little disc as i can as this seems to produce better quality sounds, with better depth and lets my brain do the thinking rather than jamming up the processor. I don't know if that helps you at all but thats just what works for me here in Minnesota. Let us know what your findings are with trying different things. HH -Marc
 
Hershey 1 where in Tn do you live? I live about 30 miles northeast of Cookeville Tn. Last night I got to thinking about my post and some of the earlier replies and I was going to try some test in some of the harder to detect (red clay) ground I have here at the higher elevations. I have noticed the users that are using deep off with high gain etrac's generally run 27 or higher in auto plus 3. I've noticed my etrac wants to run in the mid teens up to around 21 wat few times I have had in over the red clay. I appreciate your post. This forum and its people are great.
 
Hershey1 and Grouser have explained it right as far as I understand it.

Deep on adds filters to help read the numbers better on really deep targets. I just gained more info and insight from what Hershey1 said about relic hunting with deep on and slightly lower gain at the factory 24 default setting.
I will have to remember that as I mainly coin hunt.

Fast on turns off some filters and it also clips the signal shorter due to the machine resetting itself faster. It's ok in trash where you can run sounds long to make up for that like Marksman7 found down there in Australia on his videos here.
It makes good targets really stand out in the trash with fast on and sounds long, I tried it out after seeing it and it does help.

Gain amplifies deep targets to be louder and does nothing for shallow targets so they could both sound the same depending on how high you run it.

Like Goes4ever and MHirschmann I do the same thing and run my gain at 28-29 so as to hear any really deep signals without too many iron chirps so don't go to 30 on it as it seems to help with that.
 
High gain amplifies deep signals, like I said above I run mine at 29...........But I can tell CLEAR as a sun shiny day the difference in a 2" deep memorial and a 8" deep wheat, JUST by the tone. It amplifies the signal, but a deep coin still is softer sounding. A shallow coin about blows your eardrums off, and a deep coin is solid but not blaring loud.

Does anyone else agree, or is my etrac different from everyone elses?

Also I do not notice any clipping on my signals and I run fast on....always 100% I normally hunt old farms and the iron is usually pretty high. Coin signals jump out and are easy to hear. There is no clipping of signals. I use normal sounds, I have tried long, and it is just plain annoying to me, makes pinpointing very difficult. I do not use the PP button ever. I only use the wiggle back method for PPing which is more effective and quicker. It allows to to "hear" the target your PPing. If you use the PP button the etrac will lock onto the strongest signal which very well may be the nail that is a inch away from the coin your trying to find. In long sounds this method I use to PP makes it almost impossible.
 
Ok, thats it. Im going for it. Raining here, but I just got off phone with a friend about 100 miles away, no rain. Wife is wanting to go to Natchez anyway. He has a spot we can hunt.
Im going to use TTF, all afternoon. Relic screen with top of screen blocked, except for a silver hole.
Im turning deep off and running gain up to 28,fast on,Normal Response. Will experiment with manual sensitivity today.
Ive been wanting to learn TTF. So begins my education.
Beats sittin in the house,lol.

I agree but I'm not sure how much softer the deep ones sound, though they are softer. I mentioned that in my video but do wonder how much of that is just the signal not being as steady if you know what I mean? (edit - by steady I mean those nuances that smooth, for example, seems to take out. At depth thing are more nuanced as there is more between you and the target.)

Fast On definitely clips my signals. I have made that comparison on video many times. It is the most noticeable expert setting change imo. Maybe your hearing is clipper impaired? :crylol:

I agree with you, long and smooth drive me nuts. It is just too artificial sounding and too long. And smooth, smooths the nuances of the sound. Once I had it on smooth by accident and after 5 minutes I was like "What the heck is wrong with the ground here" LOL. I then thought in silence (yes, coil not moving) and realized when I last moved the setting I moved it in the wrong direction. I thought my E-Trac was broken. That all said, on deeper targets I can see it's value.

Regarding PP, yes you are spot on. One thing I have played with is using the normal default mode as it can pick up a coin close to iron, this I verified a few times. You just need a shorter sweep, which the E-Trac likes anyway. It is too bad the E-Trac doesn't let you adjust the pinpoint sensitivity. Or even have shortcuts to easily switch between pinpoint modes. Wish it had a more "live control" like my V3i as that would make the switching very fast and less cumbersome.

no my hearing is not clipper impaired...lol. Maybe my hearing is just good enough that I pick up those high tones easier, clipped or not? To me coins sound so good and never clipped when running fast ON. maybe I am just odd :look:
