Altered signals due to depth and corrosion

[DetectorBase]

I wanted to split this post up from my conductive/ferrous question. Again, coming from XLT world to Minelab SE, I have to bridge the gap so I can start finding the good stuff with this detector.

In my area Indian Heads/Barbers are in 4.5" - 6" depths usually.. and in 'normal' soil. Nickels and coppers seem to hold up pretty good, but I do get a halo. One edge that I was able to learn with the XLT was how coins would read below what you'd expect for that target.

For example pennies would normally read +70-+80. Nickels normally are in the +20 range, etc. But deep pennies would read at +60 in my area. Deep nickels would read in the +40-+50. I think this is due to the halo or corrosion surrounding the coins. Know this, really increased my finds, and I learned what to look/listen for. That's why alot of these coins are still in my area.. people pass these signals up!

Now, I have the SE. Same area. Same depth of targets, but want to know if similar changes in target input will happen with the SE? If so.. how? Will the tone be 'lower' for deeper coins, or will the high conductive squeek still be present at a Barber dime 6"? Will the smart find target not be in top right.. or display mid range.. or more in the ferrous range?

Thanks again for everyone's advice. I'm excited to get some keepers. The ground is still solid frozen past 4".. but soon it'll be diggin' season again.

On the explorers you should not hear differences in tone quality based on depth, but the sound will be much softer, which is due to the gain setting. It will take you a while to hear the difference as you come across deep coins. And the digital numbers should not be effected by deep either (according to minelab). Actually 6 inches is not all the deep for minelab equipment, you should hit those no problem.

Also, learn to use the smartfind screen. The area where the target hits will give you as much as, or more info when compared the digital readout. (My opinion) Especially on targets close to trash or with falsing iron. For coins targets, anything getting up in the top right quadrant should be investigated. An coin around trash will bounce around on the screen depending on the sweep direction, but in certain directions you can get it to repeat top right. On the digital readout the numbers go all over the place, inconsistently, which at least for me is can be confusing. The SE will be able to sniff out masked more efficiently than the concentric coil on the XLT if you know what your looking for.

And the biggest tip from XLT to SE......slow down! The slower the better, and the slower the deeper you will be able to detect. If you have normal soil where you are (no rocks), there are coins >6inches most likely. Go over all your old spots, you'll like what you'll find.

As Dreamweaver said, slow down. The SE needs a slower sweep speed than the XLT to process the extra information from the 28 frequencies. The deeper targets especially need a little extra time because of the extra ground matrix that has to be analyzed.

Once your ears become trained, you will put duct tape over the screen. More good targets have be left in the ground because it didn't have the "right" nunbers.

Sounds good. I've been running AM with Ferrous tones.. found a couple of good coins in the hunted out park, but my luck feels like it has run out. Digging lots of pull tabs lately. I went from smartfind to digital.. maybe I'll go back to smartfind.
