[QUOTE="PhaseTech, post: 287429, member: 3149"] A small DD coil like a Detech 8" DD or a Minelab 10x5" Commander DD will reject iron quite well. Accuracy and your potential to miss gold suffers the higher the mineralisation and the higher you turn up your iron reject setting. While it is a great feature to have, if you don't have a GPX to start with, it probably isn't the best choice to purchase just for it's discrimination abilities. The best discriminating machine is the CTX3030, but it's sensitivity to small gold isn't that crash hot. However, it will pick up a 0.7g if it's close enough to the surface. If you are after "the most economic" option that will actually do the job, it'd be a toss up between the Eureka Gold $799, or a Nokta Fors CoRe $860. If it was me in that situation, I'd be grabbing the Fors Relic as it has a few extra tricks up it's sleeve, mainly iMask which is like a secondary ground filter. The Eureka Gold doesn't have a full discrimination mode like the 705 or Fors units, but the Iron Reject is quite good, and works in a similar way to the Iron Reject in the GPX series, but being VLF, does it a little bit quicker. A few options there, you just have to weigh up features vs price. [/QUOTE]
