We have a new question topose to the group.

[NH Bob]

Anyone want to help with this question?
Bob I like your post, I think it was a great idea......but I am still confused as to where you got turning your gain down to 4 or 5 would cause you to miss lots of signals, while in deep, loking for fainter, sounding deep coins???? See, I don't really bother with the screen ID until the tones tells me to.

With a setting of 1 the target signal will
be unamplified. Weak target signals
will sound soft, medium target signals
will sound medium and strong target
signals will sound loud. There will be
greater differentiation between target
signal strengths. The weakest signals
will produce an accordingly faint audio
and may not be heard.

With a setting of 5, the audio response
is being partially amplified. Weak to
medium strength signals will give
proportional volume, but strong signals
will not sound much louder than
medium signals because the Volume has
reached its maximum limit.

With a setting of 10, all signals
will be amplified to a very strong
audio response. It will be harder to
differentiate medium to strong signals,
but even weak target signals will be
easier to hear.

Now , I've read that page over and over and again I have to ask where does it say "a gain of 4 or 5 is causing you to miss lots of signals"??? It does mention something to that effect at a gain of 1. The reason I picked on your statement, was not to be mean to you. But when I first got my SE, people would mention "digging the faint, deeper signals" and I had no idea that until you turned the gain below 5 or 6, you couldn't hear enough of a difference to tell the deeper coins from the shallow ones. That is very important information, and at some sites, the difference between digging eight pounds of memorial cents compared to digging wheats and silvers.

Bob, the manual also states that the factory preset gain level is 8.

As you posted from the manual,
"With a setting of 5, the audio response
is being partially amplified. Weak to
medium strength signals will give
proportional volume, but strong signals
will not sound much louder than
medium signals because the Volume has
reached its maximum limit."

This tells me that at a setting of 8,our medium and strong signals are probably going to sound identical,
and our audio perception of signal size (and possibly depth) are non existent for medium and strong signals.

I don't know why Minelab chose 8, interesting to find out eh!

I don't know about how much softer our progressively deeper/smaller targets are going sound at this factory
setting of 8, I've never gone to the trouble of checking this out...

I have chosen to set my gain at 7, I've happily run at this setting for a long time now and feel that I have enough
variabilities what with changing inland soil mineralisation, plus dry or wet salt/sand when beach hunting that I
would rather not be chasing my audio gain levels also.

This is just me and my SE ...

I tell ya though I really like to read about every ones experiences though ~ keep it up guys!

But I left one part unchecked.

At the school yard I had a soft silver sound, it was unstable, hard to get the curser to land solidly on one spot, and by remembering talk about gain and deep on, I had deep on and turned it off, now with deep off and fast off the curser actually got more stable, and I had gain at 7, and I could barely hear silver, so I change it to 8 and what a diff. it made, if I wasn't going slow enough using 7 I would have walked right over the coin. So I need to try it in diff. soils and beaches but I think from what I have experienced here is deep is staying off for now ecspecially in noisy grounds like this school(hot rocks and electrical noises) and if I choose to go slow 7 should be ok to let me know a deepy or on edge coin but bump it up to 8 too double check it.....and I will also keep sens. up as high as possible cause that does make a big diff on ID ( sound) It actually makes it harder when there is outside influenses, cause the detector gets crazier

But the one thing I didn't check is if I turned down gain to 6 or 5.....would I still hear silver...next time I will check....but I don't get to many like this so it maybe awhile till I can do this . My thought is I would not hear it....since 7 was barely audiable.

This is a noisy place and I think if in stable ground maybe lower gain would be ok....but I got to try it and find out for myself....I really don't care what the manual says....its a good starting point but One has to experiment for themselves to see what works for them at the diff. places they hunt, it constantly changes from one spot to the next, so it is up to us to figure it out.

This is really opening my eyes even wider....and making me more aware.....Thanks Bob and others for this education.

By switching from 8 to7 made no difference but switching from 7 to 6 made a big difference. Enough so that it convinced me to stay at 7 on the SE.
Just for conversation sake, on my XSII 6 was the setting I used most of the time.
These #s work for me in my location .

I have found that point where a deep signal still sounds deep but you are confident that you are hearing those deepies.
One # less and I can barely hear some deep targets. Move up one # and bingo. To go to 8 or more is the point where all signals start sounding the same.
This is in my soil.

Bob , I only use that setting in a very specific situation where all I want, is to concentrate on the faintest signals and ignore everything else. Say the clad was at 3 and 4 inches and the older coins were at 6, because there is not great difference in depth, the gain at that point needs to be lower (about 4 or 5) so you can hear the depth difference. If your clad's at 3 and 4 inches and older coins are 8inches or better than a gain of 6 is enough to tell the difference, you're basically using the highest number you can get away with.

I like the soft sound of a deep coin too and ran my XSII at 6 all the time. And, like you loved it. It was so easy to tell a deepie.
When I got my first SE I had a terrible time with the falsing. I called Minelab and was told to turn the gain down to 3.
Ya, That's what I said. It worked to quiet the machine but by doing so I found through a few tests that I was losing depth.
I mean by that, that I could not hear the deep soft tone of a coin 7" or deeper. That 6" coin sure sounded pretty but the trade off was no more holes over 6-7" deep. Until I played the gain up and down and heard an amazing difference in the volume of a deep coin. I have dug 31 large coppers in 3 days and all were 10-12+". If my gain was at 3 or 4 as Minelab had suggested, none of those coins would even be talked about.
I might add that this was early on when Minelab was struggling to come up with a solution for there slimline coil problems. I am on my 3rd SE and can push the settings to the limit now that I've found the FBS1050 coil makes all the difference in the world.

I use my machines audio response set to pitch hold ...

Anybody else had a go at this ???

I find it handy to be reminded of the last targets pitch,
especially when ferreting amongst numerous targets.

My Oldphartitus dictates that reminders are sometimes necessary !!!

Bob,
Desmond Dunne from Minelab Ireland says real good things about pitch hold,
he says that you can get better signal responses from your deeper targets while in pitch hold...

I haven't checked this out __ I'm just happy with the previous targets tone staying around until my next hit...

If I can find the link to his movie I'll post it on this forum.

~ I don't know if it will work or not though.

 

[SNOWY]

Bob, I don't know if this will work, but here goes!

each of us...and that's what this forum is all about. I hunt only sites that have been beat to death for 30+ years and I run my gain at 10..yes 10. I don't have much surface to 6" coins and even if I did I wouldn't care. It doesn't bother me to glance at the depth meter when I get a nice high coin hit. I want to hear that 8" to 10" coin as best I can and running gain at 10 works great for me. That is why I love this forum because it lets us all know that there are no perfect iron clad settings. What is does is give us all different options to try and experiment with...which then allows us to incorporate it into our own settings.
