To Track Gb or Not?

Correct me if I'm wrong...... But the Auto Tracking (if you continue to swing over an actual target) will eventually re-balance the machine after a number of passes to the same target. Swinging over it a few times should do nothing. The X-Terra 70 is designed to function when in motion, but continually swinging the coil over the target when in Auto Tracking can mean the detector will eventually sync with the target. That's what it's designed to do in soil: gradually adjust itself to the soil as the density and mineralization varies. If you hover over a target for too long with this setting active, the detector may suddenly assume that the ground you are now moving over is composed of the same material as your target and will cancel the target out as it adjusts to accommodate the new material.
You have to be smart enough to turn it off when scanning a legitimate target that arouses your curiosity for more than a few moments or don't use it at all.
If the Ground Tracking did not exist, you would need to re-balance your detector every few dozen feet to maximize penetration in the soil - unless you're walking around in a flat paddock. With Ground Tracking on, the machine will constantly adjust to the variations, density and content of the soil all by itself.

There is no right or wrong, there is no black or white, just shades of gray that you figure out on your own. Three different methods are provided so that "you" can tailor the machine to "your" liking in different hunting conditions. If your hunting included highly mineralized & rapidly changing soil conditions, you'd get up every morning and kiss that X70 full on it's Tracking Switch.
The choices that the X70 offers is so you can personalize the machine for your uses, but you have to avoid the bellybutton opinion that just because you don't find a particular mode to your liking doesn't mean others won't. And neither should others try to impose their manner of use on you in regards to Tracking.
I'll relate a little tale about a detector I happen to like a lot, the Fisher Edge. It has one method to GB, and that's it. There is also no readout or indication of where the GB is, only a tone to indicate it has GB'd or not. One day I took it to an ocean beach to try it out as far as how it would handle the salt & black sand. As luck would have it, it had rained that morning, so all of the sand was wet, even where normally dry. The Edge would not GB period, and it was very noisy if I tried to hunt with it no matter where I had set the sensitivity. Why? Simple, the GB software routine in the Edge reverts to the last known good GB point if it cannot arrive at a correct GB.
So there I stood at a beach 70 miles from home with a detector in hand that I could not use because of a very restricted GB function. There are no options, there is not even a means to set it back to factory default at the preset it arrived from the factory in. Luckily I always carry several detectors in case I run into to trouble or want to experiment with other detectors.
Contrast the above with having an X70 in hand, Manual, Auto, Tracking, Beach Mode etc. And if you saltwater beach hunt where there is black sand, you had better be in Beach GB mode with Tracking ON, and you can take that to the bank! But in mild slowly changing soil you can opt to leave her off. Try it both ways, won't hurt a thing, and if you do end up someplace with nasty ground, you have a machine in hand that can adapt at the push of a switch.

I look at it this way, Auto track may track out deep weak signals if you use a tight sweep over the target but in general on most mid depth 6-8" targets it won't and on targets you can locate using a broader sweep where its seeing more ground than the target it won't track it out either. This just makes sense to me and is how it seems to work in the field.
Now this is where it get sticky and maybe some belly button lint involved.
In moderate iron I found that tracking did a better job lighting up some of the tougher co-located targets. Its not that the 70 wouldn't see the same target with the GB locked, just that it got a better tone from different angles of approach so made those iffies easier to locate with less gridding of the area. My thoughts are that a fixed GB over clean ground does not always equate to the best GB setting for hunting around decomposing iron. With manual GB machines a lot of people use a slightly positive GB setting for iron hunting with better results. The auto track function seems to recognize the iron and makes the adjustment for you. When I mentioned seeing this during my testing of the 70 to Andy S and Dick at ML they confirmed that auto track does help with iron handling. Anyway the only way to see if it works for you is to compare both methods on an undug (preferably a 2 way signal) target the next time you are hunting in those conditions.

when I first posted this way back when, I got no response or confirmation on my "findings: about using auto track around iron.
Who has actually tried it besides me and Bjorn?

Actually I was hoping you would pop in on this one, because it shows that you need to go out in the field and experiment. What counts is finding a way to get the good stuff out of the iron, and you're one of the guys who'll work and work to come up with the best methods for you.

There are lots of guys out there that work hard trying different machines and ways of getting whats left in iron. Virgin sites are rare and we don't all live in cities that have huge parks that go back over 100 years. So we take what we can get
Actually I owe you for that discovery on the X70. I noticed it while comparing signals against the X50 you had loaned me at the time.

Maybe there is several Bjorns in here but here is how I hunt with the terra 70.
On open fields where I cover lots of ground i allways have track on. No contest, maybe because you are guaranteed to see different groundconditions when you cover more ground.
I have a fortified town from the 1600s where most of my park hunting is done. The fortifications have been restored and plowed but no dirt was added. A screwcap can easily be at 10 inches together with a pulltab and a 1600 hammered silver can be at only 4" Its fairly low mineralized but have huge amounts of small iron and brick pieces. I dont cover much ground here. Hours and hours on a small spot maybe 20 by 20 feet.
Since I got the 6" DD I have not had it off the detector and have found that track off is best with a positive offset of 2 ( two nrs lower then perfect GB)
It will give a cleaner hit on deep targets, especially the bouncing ones at 8"-10" or more ( lol 6" coil ). I dig everything at this site and allways all metal and prospecting mode to check ferrous. Never any disc at all.
It works best for me that way for now.
