I have been thinking about a small coil for my E-trac to hunt some trashy and old nail infested sites but as good as the stock coil is at seperation would it be worth it Dixie rebel likes his 8in joey coil and Coinnut liked the Sunray 5in anyone have solid proof that the stock coil is missing enough to spend the money and loose all the coverage over the stock coil any suggestions or coments would be helpful
