I am a long time, primarily relic detectorist, but I also coin shoot, and beach hunt.  My primary detector is the Deus 2 because of its light weight, versatility, and high speed which enables it to handle iron well and it also does well in hot soil.  I think the D2 is more machine than you need and has a high price point, so I am not recommending it but do provide links to further information below.   If you want to skip all the detail below let me give you the bottom line up front: AT
