I was just wondering I see every machine is different.you would think after all this time one would stand out.thanks for the 19khz.
my whites mxt is 14 and my gmz is50
thanks brad

I imagine he will be on here soon.
Simply put, Higher KHz machines like the gold masters, gold bugs and others find smaller gold. They also find iron fragments so small that if you don't have a magnet on your pick you will go crazy digging targets.
The Falcon MD's run around 300 KHz and can find ridiculously small pieces.
Back in the day, the silver killing detectors ran around 8 to 10 KHz. The optimum frequency for silver.
I am guessing that todays manufacturers are running their units around 15 to 20 as a good compromise for all in one detectors.
Going by memory here, so someone better educated than myself correct me if I an wrong.
In my part of Alaska small gold & mild ground is the norm. My Fisher GB II & Whites GM II with 6" coils are hard to beat. Both are high frequency detectors & work great for my conditions, but may not for yours. I do have 10&14" coils for the GM II & a 10" for the GBII & that helps on more minieralized. Ground if I leave my home area.
As I understand it, the frequency is only one part of the equation, as there are other variables that are not fixed. eg. size or depth of gold, mineralization, coil size & type, moisture, phase of the moon (just kidding), etc. Lower frequency is generally better on conductive metals like silver & the longer wavelength gets better depth. Higher frequency is somewhat better on low conductivity metals (like gold and iron), better on small targets but more sensitive to ground mineralization. A detector in the middle is a compromise. In the field, what works best in one small spot can change just a few feet away, let alone across the country. I also understand that multi-frequency gold nugget detectors don't necessarily solve this problem either.
Nokta FoRs Gold, a Gold Cube, 2 Keene Sluices and Lord only knows how many pans....not to mention a load of other gear my wife still doesn't know about!
Very true dizzy. Otherwise, the knockoff detectors if they operate at the correct frequency would be taking the world by storm. Instead, they don't perform and waste the owners time and money.
