I just read a post in the "todays finds" forum about a person finding a palladium ring with his Nox. He said the numbers were 8-10. I had usually avoided these numbers as I am looking for coins. Nickels ring up 12-13 in my ground so this is why I have avoided digging these numbers. Two weeks ago, I was at a spot where signals were extremely scarce. I got a lock on 10 that just sounded different. I was surprised when I saw a small gold colored cross in the hole. It was not deep(4-5 inches). It was a 14k gold cross with six stones. It is 1 and 1/4 inches by3/4 inches. I usually find three or four pieces of gold jewelry a year while coin hunting and every one piece I have found was digging a nickel type signal. The Nox is the best nickel detector I have ever used. Great accuracy and depth. I am getting old so I am getting selective while detecting. I will start digging these lower signals and hopefully the Nox will shine on these targets also.
