    logical progression point of view, ???????---🤠

    Crikey Paul, which word is giving you trouble here?

    Logical = makes sense in the reader's brain. Progression = the order of things.

    🤣Just messing with you, mate.🤣

    Perhaps I was being presumptuous by assuming that ML are logical.🤔

    I think it has a little bit from all three, the SDC, GM and GPZ. Not so much from the traditional GPX's from what it appears.

    As we all know, appearances can be deceiving. Looking at it from a logical progression point of view, the GPX range had made many functions that were preset and hidden in the GP series, e.g., the motion and audio filters, stabilizer and tracking speed, etc., fully user adjustable beginning with the GPX 4000. So the next logical progression of this for the more automatic and user-friendly platform of the GPX 6000 would be to have the detector automatically and continuously adjusting these parameters according to the ground conditions, the coil sweep speed and other variables. Perhaps this is in part what the Geo Sense tech is all about.

    First Nugget Of 2021

    in Detector Prospector Forum

    Posted

    What better way to ring in the new year than going nugget shooting in the sunny desert southwest. 😎 In my wanderings through an area heavily worked by the old-time placer miners, I spied an old raked and drywashed nugget patch on a hillside that sloped down to a gravel bench deposit high above the dry creek bed. Back in the VLF gold detector era, the surface rocks were raked away in order to get the detector coil right on the ground, to make up for their limited depth capabilities. Detecting these types of environments with the newer PI and ZVT tech can reveal deeper nuggets that were beyond the reach of VLF detector operators. Slow and methodical coverage of the old patch with the GPZ 7000 yielded two small nuggets for the poke today.

    Back of napkin calculation from a formula I just derived which I can explain later if this weight isn't totally off in left field in the end. 🙂 I have no idea if this works or not.

    (19g/cc * x)+(3g/cc * y)=125.8 g----> x = 25.5 - y

    So, (19g/cc * (25.5cc -y))+(3g/cc * y)=125.8 g

    Solve for y (volume of quartz or other material) = 358.7/16 = 22.42cc

    Now x (volume of gold) = 25.5-22.42 = 3.08 cc

    Gold weight --->3.08cc *19 g/cc = 58.52 grams

    Quartz weight ----> 22.42cc*3g/cc = 67.26 grams

    Rounding error due to me being lazy.

     

     

    I just saw the same method on the internet: the volume of the specie is the dry weight minus the submerged weight, which equals 25.5 grams per cubic centimeter. If the specie was made entirely of quartz, it would weigh 25.5x2.65=67.575 grams. Subtracting this from the weight of the specie, 125.8-65.57, leaves us with the weight of the gold...58.2 grams.
