Re-badged and simplified XP Deus for the African market, running the high frequency coils and just the gold program loaded. They won't sell to Oz unfortunately, especially not for that price.
I'd say this is the detector that Minelab got its knickers in a knot over with court action, trying to delay it before they released the Gold Monster onto the same market.
Buy the new high frequency coil for your Deus and you will the same gold capabilities.
