The most popular Falcon model, the MD20 with 5 waterproof probe, has become an industry standard for electronic probes of all kinds. Its high frequency of 300 kHz and unique electronic design have given it an excellent ability to find super fine gold particles that other detectors and probes cannot find. The Falcon can find particles of gold barely visible with the human eye. This Bundle contains: Falcon MD20 Metal Detector Falcon Headphones The Falcons superior ability to detect gold, silver, copper, platinum and other valuable metals in rock formations provide the prospector with a tool unavailable until now. Historically, tailing piles were created by miners selecting good ore from "worthless rocks" by sight alone. Millions of dollars of valuable ore were discarded because the miner couldnt see the metal!! Those metals are still lying in those tailing piles waiting for someone with the electronic sight of a Falcon. With improved sensitivity and more power, the MD20 series of Falcons will give the modern prospector the ability to find gold in places never before detectable. Small enough to fit in you pocket and rugged enough to be used in the field, the MD20 will be a necessary tool for every serious prospector. While designed with the gold prospector in mind, the Falcon has found many other metal detecting uses, such as: Hobby - Pinpointing coins and jewelry without touching them Medical - Locating metal fragments in the body Construction - Locating covered up nail heads Food Service - Scanning for metal fragments Wood Working - Finding metals before damaging blades Many others where small metal pieces need to be detected.
