Will be trying one really soon when they arrive down here in OZ but if they have the same great iron discrimination as the other Prizm's have they should be a top cheap little machine. I personally find the Prizm's have one of the best iron discriminating systems out. Over, or down here, in OZ on our goldfields they beat most others in that department. There is a cheap Chinese machine sold here wrongly labled the "Gold Snoop" which the importer claims beats nearly all machines up to and over a $1000. What a joke. It picks up a good portion of iron as a good solid target which the Prizm's wont even register or even wheeze on let alone give a signal. You have to turn the Gold Snoop disc up to 70% before it gets rid of them and when this happens you loose nearly all your gold, most of your coins and nealry all other relics you would want to keep. The Prizm's will get rid of all the same iron on minimal disc range and retain all the good stuff no probs. They make the Snoop look like what it is, a TOY. Im getting the Prizm 6T for that very reason, ones on the way in our shipment with my name on it. Whilst others will be digging up iron junk because their machine gave it a good call and waste a good protion of their time doing so ill be rejecting it for what it is, junk, with my Prizm 6T.
