Back in January, two Sudanese gents (both permanent Aust residents) offered me $7500 for my beat up 4500.
They were armed with wads and wads of US dollars supplied to them by US and Canadian companies that are recruiting Sudanese residents in Europe, USA, Aust and Canada to buy every 4500 they can get thier hands on and ship them back to family contacts in Sudan. They get a commission on every 4500 they buy.
The price for 4500s on Ebay seems to have dropped off with many passing in under $6000 but now it's big coils especially anything Minelab Commander. Recently though large Coilteks have made thier wanted list and I saw an 18" mono with a buy it now of $2000.
Shortly they will no doubt discover Nugget finders and the same will happen again.
I don't think anything has happened to Minelabs producing capacity, I'd imagine it's busness as usual, just there happened to be a sudden increase in demand thanks to Sudan. Don't forget that a lot of the coils are also being bought on mass by some Aussies who are on selling them to the Sudanese at huge profits. I think when the boom dies (and it will) I'd imagine a few of these blokes are going to be stuck with a lot of coils they can't unload or will but at a loss.
Recently saw one Ebayer with 3 BNIB 4500's and they all passed in below retail
