Would like to suggest Sorex Pro used for sale.
About two years old.
Overall in a good condition due to the term.
9.5" by 12.5" at 7 kHz coil will come with this detector.
A dust cover will be also in the set,though the cover has a tear made by the previous owner,but still carrying the option.
Let me know if you are interested sending me a p.m. for details.
If you want more coils,let me know as well.
The cost includes Express international shipping.
