About This Coil
This isn't just another aftermarket coil - it's the choice of serious detectorists who need professional-level performance from their Fisher F2 or F4. The butterfly-shaped 13" x 14" configuration provides the sweet spot between depth and target separation, making it ideal for coin hunting in parks, relic hunting at old homesites, and general treasure hunting where you need to cover ground efficiently.
The Double D (DD) configuration excels in mineralized soil where concentric coils struggle. You'll notice improved target ID stability and reduced ground noise, especially in challenging conditions. The coil's epoxy-filled construction and German-made cable ensure it'll handle years of serious detecting.
Whether you're upgrading from a stock coil or adding a specialized depth coil to your arsenal, the Detonation delivers the kind of performance that finds targets others miss. It's particularly effective for deeper coins and relics that standard coils can't reach.
