X-Terra 70 Ground Balance Question

New member
I may be losing my mind, not sure, but I thought somewhere on this site I saw some mention of a type of pattern set up.....along with manual ground balancing for highly mineralized soil, I thought I had read something about taking one of the set patterns, and accepting all of the items in that pattern to help along with detecting hot soil? not sure...I have been sick the last couple of days, and may just be going insane....any help?

I would say Pattern 1 in Track(Tracking Ground Balance) with a DD coil for highly mineralized soil.

Get well soon and you might try to drink a weak mix hot toddy of boiling water, 1 pepperment tea bag, teapsoon of honey, (butter&cinnamon optional) and a 1 oz. small amount of rum, whisky, or brandy.

The only thing I cannot still understand is why does a person would have to Auto Ground Balance before putting it in Track??
 
You don't have to Automatic GB first. Just put it into Tracking and start hunting, for the first 5 seconds or so after you push the Tracking button the detector is in a special rapid ground tracking routine and then slows itself down to normal tracking speed.

many times I have a hard time finding a true metal free area and just put it in tracking and start hunting. If I come across an area I think it fairly clean I will put it into all metal check it and if it is clear I will GB then
 
Yes, when you enter Tracking mode the machine goes through a pre-programmed routine. No matter what the GB setting it will adjust to what the computer determines is the best setting.

Ok, I currently have the double D med. freq. coil on there....just getting a bit worried about the mineralized soil in Virginia for this upcoming hunt....

Ok so I put it in track. What about once I hut a target? Do you really need to take it out of track and the put it back in after recovery? What are the odds of nulling out said objct. I like to use track but worry about this aspect, beale.
 
I think it is way overstated. I have went over a target time and time again, turned 90 degrees and continue to go over it, and never turn track off, I have NEVER had the x-70 "TRACK" out a good target when I investigate the signal.
 
Tracking has two helpful characteristics.

1. If you don't know how to Ground Balance or have little confidence in doing it properly, then tracking takes care of it. The advantages of a fixed GB detector with the performance advantage of a perfectly GB'd detector.

2. In ground that varies say every 10 ft it will adjust for you. This can present an advantage in mineralized areas where the ground changes quickly.

Measure the ground to get a true idea rather than guess. Take some targets and bury them to test your settings where you will be detecting. I'm always amazed that so many supposed experts & gurus etc don't suggest this when asked this exact same question. Take all of the coils you have, connect them, test the targets. Don't assume! There are ground area types where the 6 inch HF DD will be the DEEPEST coil of all!

Thank you. I will now be using track all the time, Beale.
 
Hold on with that all the time!:) The Exception confirms the General Rule.:) There are instances where you might want to turn it off momentarily once a target is found. i.e. A deep low conductor target on a Saltwater Beach, especially with Black Sand. OK, why in this instance?? The Tracking in Beach mode is more aggressive(faster) than standard dirt mode. And you could track that target out within a couple of swings.

But even with regular old dirt hunting there is a technique in Chapter 18 of my never to be released book "Ninja Secrets of the X-terra":) that will keep you from having to touch the control panel if you are concerned that you've begun to track out a target. Assume you've located a weak target and are making several swings from different directions to make a dig/no-dig decision. You think you are beginning to hear the audio weaken. The two immediate things that come to mind is to go into Pinpoint or turn Tracking Off. But there is a third option that can be used "most" of the time. If there is any ground adjacent to the desired target that is free of metal, simply move the coil to the side and make a few quick swings, which will make sure the detector is reading the actual ground phase and not taking your target into account. It also allows the detector time to re-track back to the ground phase if it did track off. If after swinging over the clean ground and then returning over the target you notice the audio got stronger, then yes you were beginning to track it out. This same method is also a way to check your own fears about whether Tracking is causing targets to fade by tracking them out. It answers the question that going into Pinpoint or turning Tracking off won't.

I agree with Barnacle Bill. I have never auto tracked a target completely out but many times the signal weakens. I either turn tracking off and back on or swing over fresh ground and the signal strength returns immediately. HH Nampa 23
 
So I guess I will stick to my current method. I put min on auto GB then I may run track for a bit after a whileand back to normal. I do this 2 to 3 times per hunt just to make sure I am keeping up with the changes in the ground, Beale.
 
Thank you very much Bill, that's terrific info! Is the 'only' difference between the regular Track and Beach Track(umbrella icon), is that Beach Track has faster tracking?

I agree with you that Auto GB does not need to be done before putting it in Track(Automatic Tracking).

But Minelab says this in their FAQ's which made it a bit confusing for me:
X-TERRA: What are the best X-TERRA 70 or X-TERRA 705 settings for nugget hunting?
Always Noise Cancel and Ground Balance before switching on Automatic Tracking(Track).
http://www.minelab.com/usa/consumer/knowledge-base/faq#2750

I think Minelab is either wrong on this or it is a typo error.

Also with their Minelab SD-2200 and GP(X) PI machines they stated that there is a bit more depth in Fixed mode than in Tracking mode. Also with a threshold, either very tiny nuggets or deep very faint signals may Track out on a repeated pass.

No, but I can't discuss the other differences.:)

That portion of the FAQ has to do with Prospecting Mode. There is a possibility that the ground in Gold bearing areas may be so mineralized that the initial Fast Tracking routine may time out before it arrives at a perfect match. Therefore just to be sure in a highly mineralized area like that, I am sure that getting the detector into the ball park first is just insurance to make sure a good GB is attained.

A good tight(accurate) GB can be very important in high mineralization:

From what I understand and I have not hunted in those conditions just going by what I have been told, the ground can change dramatically every few feet and you need to be right on with the GB which tracking may or may not be able to keep up with.
