Filled with mental images of discovering viking swords, borre jewelry, cold coins, rune stones, ship burials, and the Norwegian equivalent of Sutton Hoo, I eagerly set out. The first day I dug every signal and -- surprise surprise -- found plenty of modern iron junk. I would say there is a piece of iron about every two meters. I called it a day after an hour or so.
The next day I decided to try to discriminate against iron to make my journey to archaeological glory and staredom somewhat shorter. I chose the "jewelry" mode on the machine where it will not make any sound signals for iron. Now I could actually walk a fair bit without the company of constant beeping sounds. And when the machine for the first time beeped with that higher-pitched sound signalling non-ferrous metal, I could barely contain my excitement. But it was iron, again. And so was the next find, too. And the next 5-6 finds until I gave up. The signals are clearly non-ferrous, but after starting to digging there might be a mix of ferrous and non-ferrous signals, and eventually all there is is iron trash.
I noticed that the signals on the display are typically either completely to the right side of the non-ferrous area, or completely to the left side of the ferrous area, and often jumping between these two extreme positions. Very rarely do I get signals from other areas of the non-ferrous range, and when I do, and have started digging, the signals will usually change to becoming ferrous and eventually, to my disappointment, all I despondently find is a nail or piece of iron wire.
Is the machine malfunctioning? Or am I? And how can I find those viking swords in a field rich with modern day iron rubbish ?
