SE observations...what say you experienced types?

[greasecarguy]

Did a bit of testing in my garden this evening to attempt and simulate a real situation. I hear a sweet sound over the silver, sometimes accompanied with a mild "bang" ; I did hear this the last time I actually found silver in the field. too. Also hear the "warble" described.

I noticed that with fast and deep on, I seemed to get much better depth. Do we all agree here? What exactly is the trade off?

Also, I placed a large piece of iron next to a silver coin, however, when nulling, obviously, I could not hear the coin. Once I changed the iron mask, I could hear and see (smartfind) only the iron. How is it that a good target may be discovered next to iron? Has anyone mastered this? They both sounded pretty good.

I also noticed with the silver the smartfind will sometimes move and occupy the top right, even go off the screen a bit...kind of like the top 1.5 boxes. For some reason I thought this would indicate trash, however, I see I need to dig these now.

A fella on another forum mentioned his vision can tell a silver coin in a filed of clad...do you think this is possible? If so, I need to learn this.

Although I am making some progress, I have a long way to go, so any help is appreciated.

Also have noticed good tones on the lower right smartfind...any ideas waht or why?

Best,

Aaron

I dont use the fast on very often just because i feel i get a cleaner longer tone with it off. When moving as slow as i do in trash i honestly dont think im missing many close targets. According to one of the Minelab geru's with fast and deep both on they CONFLICT with each other... what ever that means. I beleave he ment.... fast is ment to recover quickly while deep takes a little longer processing look at the data. I also think its a combination of all your settings. Threshold tone makes a difference to some ears.

You said you put iron next to silver.... were they freshly burried? Newly burried targets react differently. There tend to be a lot of varibles with burried targets thats been there awhile.... mositure, air pockets, minerals, bleeding, corroision...ect. I think a lot has to do with the angle of you and the target when trying to get those close to iron. It may just be a bounce toward that tends to stay toward the center of the smartscreen. Sometimes centering the target with some quick wiggles of the coil or pinpointing helps. The problem there is it likes to lock on to the closest target or largest target... normally iron. Rarely are they exactly side by side like you might do in a test garden.

The only time ive seen my arrow burried in the upper right corner is on hotrocks with a digital reading 00-31. Did you take a look at the digital reading you were getting. Just like big silver for me ... oddly comes in sometimes 00-25, unless its closer to the surface.

If those good tones are coming shallow from the right lower cornor.... likely its crown caps. If deep ive found V nickels sometimes hit there. Take a look at your depth it can tell you a lot when dealing with targets. Im sure you are going to get a LOT of different answers to your questions since no two people or machines are alike. Seems you are on the fast tract to learning your equipment. I think the best way is to keep digging those targets you question and learn from what you saw and heard.

I appreciate your feedback Dew. I never thought to look at depth whence hearing a good tone in the lower right but will pay attention and dig some of the deeper ones.

Also interesting that most will not us fast and deep on; I clearly saw a significant improvement in depth here.

I did not look at digital on the silver next to iron but will do so. It seems as though the processor takes a bit of time to adjust to the 2 displays...I guess 10 or 20 seconds, but I often perform this.
Yes the iron was recently dug...so recently that I would consider this portion of my test to simulate more of an air test.

Your display does take a little longer sometimes based on your IM and sensitivity settings. I cant say you are wrong on the Fast and Deep on i beleave Mike Moultry uses both and i think Andy recommened it in his book. I just know what seems to work for me and im still finding deep coins. If you have read Andys book you saw a LOT of various hunting styles and settings... so in your area try it. I think we all test settings until we find one that gives us confidence that we are getting the best depth and TID.

i seem to get the same thing in my test bed.......signal seems to hit harder

From what I understand that they don't conflict but when you use the one the other one ends up compensating for the other rather than having an added effect. So if you are using fast and deep together it is not going to be faster because using the deep slows the machine down, the fast might just end up compensating for the extra slowing caused by the deep and so if you really want it faster you would have to turn the deep off. Does that make sense? I am not sure its just my understanding.

Page 30 and 31 in Andy's book explains in detail what 'fast' and 'deep' settings do to the detecor. It's not as simple as it might seem. I don't think you can just read it. At least I had to study it a bit to make sense of it. It's not rocket science but there are some new concepts one might not be aware of. You know what "Shutdown time" is. It's not how long it take the detector to turn off when you hit the 'off' button. Regards...Jim
