When testing a coin on the 800, in an air test, I found that it only will detect on the right hand side of the coil, the side that the cable goes to but will not detect the coin in the middle or on the left-hand side.
The coin registers -5 to -6 solid on the display in all modes. Is this a problem ?.
I tested using lots of different coins and they would detect on left/ right and in middle of the coil. If you put sensitivity down to 10 or lower, on all coins you can see that it is more sensitive on RHS ( cable entry) of coil but still register on all other areas of coil. Could this be a problem or a design fault.
The coin is a sunday telegraph commemorative medal of queen Elizabeth and the queen mother.
