The new Teknetics Eurotek Pro will probably beat either of them. It's $219 with an 8" coil
(concentric) or $299 with 11" DD coil. Large numerical ID. Iron response can be set to loud, soft, or silent with flash. Detects coins near to junk. Great in iron soil, designed for European detectors that have in many places 1,000 years worth of iron build-up
Can usually ID most coins pretty good to 8" according to manual. Depth reading to 9" in no motion pinpoint. New proprietary circuitry makes it work well in bad soil, even though it has preset ground balance. Best wishes, George (MN)
