I have never owned an Explorer so I have decided to try one since my detector buddy has been using one for years and finds more silver coins and jewelry than I do. So I made a trade with a local detectorist for his Explorer SE with 10" Slimline and 8" FBS Coils. So far I am very impressed with this detector. It will take me a while to learn all the potential of the SE. Already I am digging deeper coins. On a volleyball court I dug a dime at 10 inches next to iron that we have passed over many times. So my next move will be to obtain the 11" Explorer Pro Coil or an 12"x10" SEF Coil. Any feedback on which of these coils to get will be welcome. Any chance i could trade my stock 10" plus 8" coils even for either the Pro of SEF coils?
