how deep can the x-terra 70 get in very mineralized ground ?

Your question is very broad which makes it tough to answer. Some people think they have high mineralization when in reality it's quite moderate. Then there's the question of what kind, magnetic, conductive, homogenous or variable. Hot rocks, cold rocks, hot gravels etc. etc.

Probably your best bet to get the info you need is to locate someone using the detector in the area that you plan to hunt, their experiences will be invaluable. It wouldn't hurt to post what area you will be searching in and what you are looking for. There are many more lurkers on this forum than regular posters, and one of those lurkers may have the information you need, if they can be prompted to reply to your post.

We have what many agree is some of the "worst" ground in the world on the Australian Goldfields. It's so highly mineralized with magnetic soils and high-volumes of iron ore that a majority of lesser detectors simply can't cope. My friend and I just returned from a region just north of Bathurst (Australia) and he got so frustrated at being unable to balance his detector there that he simply gave up. We went out on three major digs and he quit within an hour on all of them. I had no problem whatsoever with the X-Terra 70 and found targets clearly amongst material that otherwise clustered to the magnet on the end of my pick-axe. Most targets appeared to be close to the surface although i dug out a few items that were 9" deep. Larger targets showed deeper but I realized what they were and did not dig those. I got the impression that anything down to about 8 or 9 inches was easy to spot though. I was actually happy at digging the odd nail out of the ground simply because it showed me that the detector was working fine in an area where other's were failing to operate.

It is VERY important to use the High Frequency optional coils with these detectors though... like the DD 5x10 Eliptical.... which was specifically designed for use in these types of soils. Many other users here seem to think this coil does well on the salt-water beaches as well.

Lurkers don't post, they just read the posts of others. To get an idea of the number of lurkers, look at the number of views of a post as opposed to the number of replies. i.e. A post with 200 views but only 4 replies, lots of lurking going on.

Has ever got anything to say when I do Post. :rofl: I am one of the worst at Posting. I am GUILTY. :shrug: . Maybe I just need a Hug. :cheekkiss: Later, Jerry aka Tinfoil
 
I have had my X-70 almost an year now, and hunt all kinds soil8l, from nice sandy soil, to clay and In USA in State of Va. has some worse soil it not just bad " It "Hot" The key to any detector is bad soil is stability , coil choice,and good Automatic Tracking, or true All Metal mode. The X-70 has all above . The 5X10 Elli cal 18freq coil is stable and can handle toughest soil. I use 10.5 DD 7.5Freq most time. With this two coils and others you can switch to is true advantage of the X-70, you can hunt anywhere just by changing Coils!!
 
even though I have nothing to say. I just don't want you to get a complex! :razz: :rofl: I'm still working on the lurking smiley. I will probably have to send an email to the Guv to see if he can add it to the list.

On a serious note, I've been posting to this forum since it's inception. During the past two years, I've noticed that the popularity of the X-Terra is only exceeded by those willing to take the time to help others learn more about it. If you were to look back over the past two years, you'd find that most of us who made the initial posts are still here. But, many of us don't respond to every question simply because there is a whole new group of X-Terra users out there, willing to share their expertise and experiences. And that, my friend, is a good thing! We "old timers" are still here to add our two-cents in, whenever called upon. But having such a broad base of users has made this X-Terra forum one of the best metal detecting forums on the internet. From the prospectors to the relic hunters to the coinshooters, I appreciate everyone who visits this forum. And whether they make a contributory post or simply learn from the experience of others, you're always welcome here. Thanks for sticking around! HH Randy
 
I used the X70 w. HF DD on Mc Gee creek last year (found a small murcury coated nugget too) where the Garrett Infinium was more or less shut down and, across the Tulameen (on Champion Crk) a guy with a Minelab PI had to give up. ..Willy.
 
Willy, that's the second time I've read about someone finding a Mercury Coated Nugget.

May I ask, is this mercury from someone who was using it to collect small nuggets (apparently mercury was used because it adheres to gold and helps collect the smaller pieces, preventing them from being lost during panning) or was it a normal occurrence since it occurs naturally and would probably stick to any nearby gold? I know that Mercury vapor is considered incredibly toxic in the USA, do you remove it from the nugget or leave it there?

/ I think the Old Timers may have used fire to vaporise any mercury adhering to gold in their shovel scoops after a days panning... not entirely sure about that though.

Apologies if this is a stupid question to ask.

Cheers,

Marco
 
The old timers used to set up mercury traps in stone depressions or wooden boxes. Sometimes they'd also set up flash-dams. Eventually, the murcury would amalgamate with enough fine gold and then it would be retorted off. Off course, there was lost mercury associated with this practice, which would end up coating gold somewhere else. ..Willy.
 
You can bet that Lurking Smilly will be one of the ones I put at the end of the very few Posts I do Make. I :inlove: the Smiley's. Just think how boring it would be without them. Later Bud and call me once in a while. I think I still have your number if I didn't lose it when I got my new laptop. :D: :D: Jerry aaka Tinfoil
 
I hear you on that Jerry. I guess it's the nature of the beast. I've posted on other forums in the last few months, when I've had a flash of brilliance, just so that others can hopefully put the info to good use and the posts seem to get treated with complete indifference. It leaves you scratching your head sometimes. I guess we can feel out of sorts a bit if we let it. Chin up. Oh by the way, I have always enjoyed your posts.

A lot depends upon the nut behind the wheel and of course an experienced operator would probably get max. depth..Personally feel its a legitimate 8 inch plus unit on a coin and if the auto ground balance doesn't do it for real bad ground do it manually as its explained in the manual...Personally I feel max. depth can be achieved running it wide open in disc. and using the 99 tones to tell targets but am sure many do well using other settings...
 
Been checking the data on the xetera 70 Will be upgrading in a few months and also getting a gold machine. the xetera70 sounds like it might do it all. I saw the data at my buddy's house and we were both thinking that might be the way to go.. Maybe I will get one for Christmas, depends on how things go.
