My Manta 1 - Mineralization

The first part of our series on the gadgets of the Minelab Manticore metal detector will focus on the work inextreme mineralization, or should we say extreme rocks.

Manticore can handle all types of "common extreme" sites so well that we had to use the Manticore to showThe demonstration was literally extreme, both with the test iron foil and especially with ferromagnetic rock. Otherwise there would simply be nothing to show. In today's episode, we are going to focus on the most extreme environments we can encounter.

Video

Before you read any further it would be better to watch the video

As you could see in the video when testing on both iron foil and ferromagnetic rock, Manticore can handle these environments, which are basically the domain of the PI detector. Of course, such environments strongly influence both the range and the evaluation of the detector. To succeed in such a location you will need to adjust the "limits" (as Peter does in the video), especially the lower one. You can't do much with the upper limit, where most traditional iron targets report.

Surely everyone is wondering, if I dig the lower iron limit, as Peter does in the video, won't I be digging problematic iron targets like iron rings etc? Of course the probability will increase, there is no avoiding that.

What the video doesn't show is another item that you can influence the detector's behavior, and that is the audio stabilizer, which you can find in the iron volume settings. Here I can recommend from experience to keep the c as low as possible, if not needed, not to set 0, in locations where there is a problemm (which you can tell, for example, by the fact that you get these fine, vague puffs of iron in the upper limit), set it to 1. A setting higher than 3 will affect both range and audio response, and neither Peter nor I use such a setting.

To summarize.

If you are in a basalt site or in a place where if you roll a magnet in the dust it has "rust whiskers" hanging on it you should do the following.

1. I'll walk the site and try to kick a few targets that end up in my lower limit. I'll adjust it if I need to.
2. If the site is also full of scrap metal, I'll increase the speed.
3. If there are small clouds in the upper limit or on the sides, I set the audio stabiliser to 1

In the next part we'll look at evaluating the LCD chart, cleaning it up in places where you have multiple targets coming under your coil at once but you only want one.
