After market Coils for the Fisher F75 Ltd

Wrong forum. J.W. Fishers is a different company - they make only diving detectors.
 

^^ What he said. Fisher Scientific Labs makes the F-75. Not J.W. Fisher.

And if you are looking for large (over 3") and deep targets in an area otherwise clear of metal trash the CORS may or may not be worth it. You may miss coin sized targets but will find a lot of big, iron junk. ;-)

They list 10" as a maximum depth/"sensitivity" for large targets. I have found dimes that deep with the stock F-75 coil. I'm not impressed.
