[QUOTE="Pedro, post: 5788, member: 121"] Hi GB, Are you sure about the reading of 13f-53c or was that a typo error. The highest an E-Trac should read in ferrous is 35 and the highest in conductivity is 50. If it is in fact reading 53 conduct, there must be some gremlins in the system. I have experienced on a couple of occasions wet grass and leaf/grass matter stuck all over the coil and found the detector gave phantom signals and was pretty much useless until I wiped the grass clippings and dried the coil. It would be good to know what coins gave what readings and what settings you were using. Ground conditions would probably make some difference to the readings as well. On auto sensitivity with a reading of below 19 you are in highly mineralized ground, so in the menu, and set ground to DIFFICULT and 19 and above on NEUTRAL. I generally find copper coins like pennies and halfpennies, if they are not too corroded, read something like 12f-44c to 12f-47c, and silvers (92.5%) lets say a shilling, will read about 12-46 to 12-47. I hope this helps a bit. Cheers [/QUOTE]
