The Nail Board Test And Sensitivity
I just watched a video of a guy comparing the new legend to the equinox on Monte’s nail board test. Sorry, but I don’t have a link to it, but I think I saw it over on the friendly forum. In the video he is using the nox and says he has the recovery speed set at 8 and sensitivity at 23. Then he also mentions that recovery speed is what’s important on this test, not sensitivity. I have to disagree. Running 23 sense on what is basically an air test with an 11” coil only a few inches above the
Yes, that's what I mean by longitudinal.
A nail creates a double beep because it has a maximum return signal when the coil's magnetic field aligns with it. Here is an illustration
The arrows show the direction of the coil sweep. The magnetic field bends outward and the nail will have a maximum response at points (a) & (c), while minimum at (b). A coin is the opposite; it will have a maximum response at (b). So imagine a nail at (a) and a coin at (b); as the coil sweeps over t
