Minelab Manticore metal detector

#1 beach & overall flagship — Multi-IQ simultaneous frequencies

The Minelab Manticore is a flagship simultaneous Multi-IQ+ detector built for serious hunters who want maximum depth, target ID stability, and saltwater performance in one waterproof package. It excels at separating jewelry, coins, and relics in heavy iron and mineralized ground. Minelab designed it for advanced and all-day beach hunters, competition diggers, and relic specialists who refuse to compromise. Its sweet spot is wet and dry salt beaches, black-sand shorelines, and any site where weaker machines choke on ground noise.
