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.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/869/029/9798690296544_b.jpg", "price_data" : { "retail_price" : "15.18", "online_price" : "15.18", "our_price" : "15.18", "club_price" : "15.18", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
