The design goal was to develop a PI that can be used both inland and on the beach. In particular, special attention was devoted to finding non-ferrous targets in areas infested with ferrous trash. Rejection is not based on target conductivity, as Voodoo provides true ferrous\/non-ferrous discrimination.\u003cbr\u003e","brand":"Independently Published","offers":[{"title":"Default Title","offer_id":50448837312786,"sku":"9798690296544","price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_c59a035f-c67b-486d-872c-966ce9e9f6fe.jpg?v=1729739869","url":"https:\/\/surprise-castle.myshopify.com\/products\/the-voodoo-project-a-pulse-induction-metal-detector-with-iron-rejection-9798690296544","provider":"Surprise Castle","version":"1.0","type":"link"}
