Part I - Metal Detecting at the Swedish Tavern Site, page 40
Recovering 1 Silver Mark Coin of King Charles XI
...The remaining Noise Cancel was the only feature that could possibly help me improve the sound pattern of the broken high pitched signals. Usually the Noise Cancel feature is used to minimize interference in the current environment by automatically or manually selecting the "quietest" operating channel.
But on many occasions before, I found another application for this feature - I achieved a better quality of sounds by simply choosing a different channel. I wish I knew what the Noise Cancel had to do with that. Unfortunately the specific knowledge of how the detector's settings and features interact with each other and how certain combinations of their levels affect the detector's performance is not readily available...
Suddenly I heard a solid "bronze" signal in my headphones and dug up a bronze relic of the period. It was nice to find a part of the hat buckle for a change!

My plan now was to find a broken signal emitted by the coin that was partially masked by nail, set the Sensitivity on Manual, and then MANUALLY find the channel with the least "noise." As soon as I started scanning the ground at the challenging spot, I received a desired signal. Of course I was tempted to just dig up the coin, but I had to finish my experiment.
I followed the instructions (page 75 of the instruction manual) and found the channel with the least interference. When I moved the search coil over the target spot, the emitted signal sounded much better - almost solid! My plan worked! Being totally elated, I began digging up my "reward."
My "reward" exceeded all my expectations - a silver coin was lying on the hole's bottom! And it was not a hammered coin, it was something better. My old thought had finally materialized: in my hand, there was a coin that I had been longing for - a thick silver piece of a larger size and almost perfect round shape!
My Coin Find #5
Besides a visible date, 1695, I could see an inscription "REX.SVE." - "Swedish King," on the obverse, but I did not want to rub the dirt off the coin not to scratch a possibly valuable piece. Even Nikolai being not less excited than I could not make me do so to expose the coin surface.
After having been carefully cleaned in soapy water at home, the coin turned out to be an admirable piece!

As the target audio responses had been improved, searching the rest of the plat was a piece of cake! Even the large pieces of railroad junk could not spoil my good mood. I simply enjoyed the rest of the evening and unearthed five more Swedish copper coins! They were of the 1/6 Öre denomination, dated from 1666 to 1683, and similar to the coins shown and described above.
