What the MF90 is built for

The MWF MF90 is a versatile, waterproof pinpointer and multi-coil metal detector designed for explorers, adventurers, and divers. It is built to operate in challenging environments, from rugged terrain to underwater searches, providing precise target identification. With its interchangeable coils, this device excels at locating metals in tight spaces, walls, and highly mineralized soils where larger machines cannot reach.

Why hunters choose it

• Interchangeable Search Coils: Includes three distinct coils (square, circular, and point sensor) to adapt to various search scenarios and tight spaces.
• Fully Waterproof Design: Features an IP68 rating, making it fully submersible for underwater recovery and diving applications.
• Pulse Induction Technology: Delivers stable performance in saltwater and highly mineralized ground without false signals.
• Interactive Alerts: Provides audible and vibrating alarms that intensify based on the size and proximity of the target.
• Convenient Power Management: Offers long battery life with fast USB Type-C charging, allowing you to power up quickly from a power bank.
• Automatic Terrain Adjustment: The ATS system automatically calibrates to rocky, sandy, muddy, and mountainous soils for seamless operation.

How it works

This device utilizes Pulse Induction (PI) technology, which works by sending rapid bursts of electronic current into the ground and measuring the decay of the returning signal. This method is highly resistant to ground mineralization and saltwater interference, making it ideal for underwater use and challenging soil conditions. As you approach a metallic object, the microprocessor analyzes the signal and triggers the audio and vibration alerts, guiding you precisely to the target.
