Are there any hunters that do the majority of their detecting with the explorer in farm fields or cellar holes , or are most of the people on this site park hunters ? The folks hunting the farm fields what coils do you use mostlty and what type of settings do you use ? Any advise would be greatly appreciated , I obtained a used Explorer Pro SE about two months ago and have been running it with the factory default settings and just incresasing the sensetivity to 26 to 28. I like the machine and the tones but not up to hunting with this for more than 4 hours. I probably have put about 60 to 70 hours in with it already . Thanks for your opinions and advise . Ezra.
