Choosing Target Separation Based on Mineralization

[MarcM]

Hey guys I just read Andy's CTX book and confused about choosing a target separation option with respect to ground conditions. My question is, what machine-recommended sensitivity level is considered low, medium, high? For example is 0-10 consider low, 10-20 medium and 20+ high?

Thanks!

Lots of variables, when you consider target separation, ground conditions and sensitivity levels. On the CTX, both Auto and Manual Sensitivity registers from 1–30. So I suppose you could say that there are three ranges....low, medium and high. Typically, the higher Auto Sensitivity setting your CTX selects, the more moderate the ground conditions. If you are hunting in the dirt, a very low Auto Sensitivity indication usually suggests a high level of positive mineralization. To maximize the performance in this type of soil, you might benefit from using manual Sensitivity, and raise the level to where it is just below chirping.

As to selecting a Target Separation to optimize hunting in a specific site, take a look at a blog post I made on Minelab's website: CTX 3030 Target Separation... more than a random choice.

Thanks Randy. I did actually read your article earlier today. I understand pretty well how it works I was moreso asking about the actual numbers behind the term 'high mineralization'. Is is safe to assume 0-10 is high, 10-20 medium and 10-30 low?

Sensitivity controls the detector’s response to received signals from metal targets under the coil, as well as electronic noise and ground noise. If we had to call Sensitivity levels something, I'd call 1-10 low, 11-20 medium and 21-30 high. As such, if electronic noise and the metal targets under the coil were not a consideration, we could reason that higher mineralization levels result in low sensitivity settings, medium mineralization levels result in medium sensitivity settings and lower mineralization levels result in higher sensitivity settings. Here is the link to a post I made that may help further explain Sensitivity settings on the CTX.
