Why buy a Nugget Finder Coil for your Minelab SD or GP series gold nugget detector? It's simple, you will not find a better gold finding coil on the market. These coils have been rigorously tested, dropped, beaten, bashed and thoroughly knocked around goldfields. The Gold Nugget finder coil has been hollowed out to reduce the weight by a large factor, this gives you more gold prospecting with less arm fatique.
