As it states in the header I purchased a 9 inch round high frequency coil last year and didn't find it to be a whole lot different than my low frequency coil as far as finds go. I am strictly a coin hunter and I really miss the ID NORM mode. I'm getting too old to remember all the different numbers for each frequency. I am now wondering if the X35 would have been a better choice. Or is there something else I can do to make this easier.
