Can an explanation of the plain language of DISCR LEVEL, DISCR DEPTH and DISCRIMINATOR?

Can an explanation of the plain language of DISCR LEVEL, DISCR DEPTH and DISCRIMINATOR?

- Detailed and accurately explanation is available on the BLISSTOOL LTC64X user guide:
http://blisstool.com/data/userguides/BL ... nglish.pdf

Before using your BLISSTOOL LTC64X for the first time, we recommend you to read detailed the user guide, in order to optimally use all its capabilities. Otherwise you can lose a lot of time in finding things already known.

I will try in freestyle to explain some important aspects of DISCRIMINATOR, DISCR LEVEL and DISCR DEPTH.

For a particular field should find the best combination of DISCR LEVEL and DISCR DEPTH. They are independent only at first glance. In practice is very important the combination of both (DISCR LEVEL and DISCR DEPTH). Overall, this is something unique about BLISSTOOL. By doing so you have variety of options for changing the behavior of the metal detector... like you have "several metal detectors" assembled in a single metal detector.

A large number of other brands of metal detectors are factory designed with 100% depth of discrimination. As a result, they miss a lot of coins in depth, particularly in mineralized areas containing iron oxides. If the coin is "egg yolk", the iron oxides in the soil are its "shell (egg shell)", ie the iron oxides mask the coin, such as iron for the metal detector and it miss the coin. On BLISSTOOL, with the DISCR DEPTH potentiometer, the depth of discrimination is adjustable from 0 to 100%, yes this is a unique, but not only that. With different levels of DISCR DEPTH in combination with an appropriate level of DISCR LEVEL, the "egg shell" may become translucent, transparent or invisible, and BLISSTOOL to detect the "egg yolk", ie the coin, that other brands of metal detectors miss in discrimination mode.

Why everything is not linear and simple? Simple things are only in the laboratory. In reality everything is much more complex, soils are very diverse, the same soil vary in depth real or just through "the eyes" of the metal detector. Yes we know that and our goal is with DISCR DEPTH and DISCR LEVEL to adapt in the best possible way.

If we imagine the joint work of DISCR LEVEL and DISCR DEPTH, as "shield" of "horizontal sheets" to the ground located at various depths, sheets close to the surface are the most dense, with smaller holes or without holes. The deepest sheets are with the biggest holes are like network with large holes. When there are no holes iron is ignored. Where there are holes the iron is detected if it can go through these imaginary "holes". How deep in the ground is the deepest imaginary "sheet" depends on the level of DISCR DEPTH. Whether and how big are the holes depends on the level of DISCR LEVEL.

Please note that on the same level of DISCR LEVEL, the holes of the various sheets are different in "diameter" = "effect on permeability"! The difference between the smallest and the largest hole, and the distance between them is determined by the level of DISCR DEPTH.

If we have replaced the imagine "shield composed of horizontal sheets containing holes", with imagine "materials or sieves", those nearest the surface are impervious to iron, and the deeper more permeable to iron, while in the latter, iron passes freely, ie very deep iron ignore more difficult or not entirely.

The example given above shows that the strength of DISCR LEVEL and DISCR DEPTH at different depth in the soil is different, ie the impact weakens, dilute. First it is tightly, then it becomes a semi-permeable and finally disappears.

The switch DISCRIMINATOR serves to regulate the range of DISCR LEVEL and (important), the slope of the imagine "sheets". They must be "horizontal" to be error-free the discrimination of the metal detector. When the "sheets" are inclined, ie not "horizontal", for the horizontal direction, the holes "change" their diameter, ie the "holes" from a circle are converted into "ellipses". This leads to errors in the discrimination. This shift is mainly due to the different soils, although the metal detector is balanced to the soil. Most resistant to different soils is DISCRIMINATOR = III, this is the most self-balancing mode. The most powerful is the discrimination (the range) in DISCRIMINATOR = I. DISCRIMINATOR = II is midway between the two. The three positions (1, 2, 3) of the DISCRIMINATOR switch, makes the metal detector in three different metal detectors, ie change its behavior.

Please excuse me for these comparisons that I do intentionally. My goal is with more affordable way to provoke you to imagine the operation of the various functions. I hope I have not lost your time.

Additional information:

Important: Please note that the difference between DISCR DEPTH = 8, DISCR DEPTH = 9 and DISCR DEPTH = 10 is huge. Details were described above.

A brief visual presentation:
1/ DISCRIMINATOR switch (force, range, sinlessness);
2/ DISCR LEVEL (level, working in width from black to color);
3/ DISCR DEPTH (work in depth, vertical, to where).

In addition, it is not necessary, the user can know how it works in theory his metal detector. It just works for him. Many people just set: DISCR DEPTH = 9, DISCR LEVEL = 5, DISCRIMINATOR = III, because most often it is the best compromise setting, derived based on experience.

In fact, everything is very simple and a vast majority of users quickly and intuitively find the best settings, especially if have some experience. If not, in practice they follow the recommended settings in the user guide and again achieved good results.

Our advice: please carry out a thorough experiments and accumulated large real experience with our BLISSTOOL metal detector. So many questions will be removed. By the way there is no reason for concern. When you test your BLISSTOOL metal detector for the first time, you will be captivated by its extreme depth of detection. Appetite comes with eating :).
