white an yellow gold and discrimination

[Murphdasurf]

Ya I know; most don't or suggest not running much if any discrimination with the sov GT for beach hunting. I am probably not alone in the fact that this is fine for the first three hours or so of a hunt but I often find after the energy level goes down a bit, but I am not quite ready to call it a day, I start to run some discrimination. My nuisance item(s) are the various types of foil many of which by my ears are so close to gold I dig them rather than be wondering about it the rest of the hunt.

I have a vary thin 14k yellow gold ring I use to gauge my disc level. It is an old ring which I don't think has any nickle in it like modern gold rings, it don't sound like a nickel. I raise my disc level just to the point it nulls out and then back it down a tad. This works to disc out most all of the foil and still give a signal on the ring. I know this may null out some good targets but it will also null out that nagging feeling of not digging a signal that "might" have been something good and extends my hunt time with less digging of foil. Nickels pull tabs and other larger gold items still sound off well also at this disc level.

Problem is I have no white gold to check this with so I am left wondering if white gold gets disced out at a lower level than yellow. Anyone have a thin white gold ring they can check with for me. The yellow gold ring I test with starts nulling out just before the ten mark.

I do not agree with any discrimination, because I assure you it will cost you, but if you insist, then heres what I believe to be true about gold alloys. It is my understanding that white gold has silver in it, to obtain the silver color. Silver is a better conductor than gold, as far as signals are concerned. If this were not true, then how do we explain, how easily silver chains are found and the gold ones are more elusive. If the unit signals on fine yellow gold, I think you are good to go, but still believe you will miss something! Whatever you decide though. GH

I think that several metals are used making white gold rings and they vary so it could probably be higher or lower than yellow gold. I have a nice sized white gold mans band that comes in lower than a same sized yellow gold ring, both are marked as 14k.

An alternative to raising your disc might be carrying a small gold ring with you when you hunt and occasionally passing it across your coil to compare it to foil signals.
