The Garrett ATX is one of the most expensive devices available to individuals. Its price is indeed excessive. That said, it is the best way to find gold nuggets. It can be easily cushioned if you go hunting for nuggets in Australia, Africa or America.
With the high price of gold, more and more Europeans are making trips to the Victoria desert in Australia (for example) and are able to generate tens of thousands of dollars in gains despite the cost of the trip and the detector. They then sell the gold in the area (a bartender is able to buy your gold). You only have to pay a low gold prospecting license ($ 24 miner’s right for ten years).
In Europe, it is only useful in underwater research (between 0 and 10 feet deep), a micro niche since very few prospectors think of raking ponds, lakes, canals, moats or rivers. And yet there are plenty of coins and rings lost in these areas. But also the submerged part of the beaches, because this detector is also able to operate under salt water.
