X-Terra 70 Questions

[xlogit3k]

Well first thing I do when I enter a new spot is put my sensitivity down to 12, Noise Cancel, Ground Balance, and then turn up sensitivity to 22 and it works good around there.

Are these good settings? BTW my threshold is set at like 18 and I am not using headphones right now.


I can easily find clad coins and they ring in crystal clear but my question is on gold. Will gold give a solid audio tone like a coin just lower? Or will it jump around on the tones and on the VDI?

Any help would be appreciated thanks.

go to Utube minelab 705 lots of vedeos

The only suggestion I would offer is to use a set of headphones. Not only will it allow you to lower your Threshold. They will also "shut out" any outside noise that could interfere with hearing target signals.

Gold jewelry of various sizes and shapes will each give different TID readings. Bigger rings will read more conductive etc. But each target should provide a steady TID while buried. The reason I say while buried is because rings can read differently when scanned "flat" opposed to when on edge. (so can coins). But if they are in the ground and not moving at the time, they should provide a steady TID. HH Randy

So if I'm scanning over a gold ring in the ground I should get a lot of consistency in the TID numbers? Should I also be getting a really stable audio tone as well? I remember with the 14k men's ring I found with the Bounty Hunter it was a consistent sound and consistent ID. The Minelab really like's to pick up flat gold rings strongly I have noticed.

May I ask what Pattern (if any) you are using to look for GOLD targets?

I usually run in Pattern 1 which only rejects a few of the iron segments far left. Sometimes I even go into all metal and 99 tones when there is less trash so I can distinguish targets better.

Des, imaging technology is already here and available on hand held units from Accurate Locators and for a next advancement I would like to see an "imaging" feature put on to a metal detector from Minelab, showing the outline of the targets shape on the screen. So this along with TID numbers and tones it will help make a better decision whether to dig or not.

For example the outline of a gold ring or small siver coin as oppose to the outline of a aluminum pull tab or brass cartridge gun shell.

Not only do we need a 6" LF(3 kHz) DD coil but also we are crying for a bigger coil and would like a round 15" DD or elliptical 10" x 18" DD coil for the X-Terra's from Minelab. For coverage for prospecting-meteorite hunting, larger homestead yards, and especially for farmers fields.

The audio tones and visual TID are both tied directly to the target's ferrous and/or non-ferous (conductive) values. As such, if the TID is steady, the tone will usually be consistent. If either one varies, it will likely be due to an adjacent target, too much sensitivity, an improper ground balance or lifting the coil. The audio tone will be "quicker" identifying the target values than the visual TID, due to processing. Therefore, you may occassionally encounter targets whose numbers seem to "lock on" while the audio response varies from one notch segment tone to another. Another exception might be in highly mineralized soil conditions where the visual TID will be inconsistent. In those sites, enabling the TID Stability mode will help to "lock in" the visual TID. But it won't necessarily match what you'd expect from the pitch of the audio.

As to consistent numbers on rings......ff that ring ain't moving, it should provide consistent numbers and sounds. It may read different after you've dug it as I've found with any detector on rings whose band is broken. In those situations, the TID will be much lower than the TID provided when the band is intact. If you ever find a ring with a broken band, you can prove this to yourself by scanning the coil over the ring with the band separated, compared to the TID when you hold the band together.
