Fisher Research Labs was founded in 1931 by Dr. Gerhard R. Fisher, the world renowned engineer and inventor who was the first to receive a patent for the metal detector. From its simple beginnings in Fisher’s garage, Fisher Research Labs is a made-in-America success story. The world’s oldest metal detector business, Fisher Labs uses the latest in technology to build the most trusted products in the industry.

Dr. Fisher, a German immigrant who studied electronics at the University of Dresden, was a Research Engineer in Los Angeles in the late 1920s when he obtained the first patent ever issued for aircraft radio direction finders. His revolutionary work in aviation attracted the attention of Dr. Albert Einstein. After seeing a demonstration of Fisher’s equipment, Dr. Einstein predicted the worldwide use of radio direction finders in the air, on land and at sea. In 1931 Fisher founded Fisher Research Labs in his garage in Palo Alto, Calif. He and four employees produced the "Metallascope," a rugged, easy-to-use metal detector. By today’s standard of lightweight handheld detectors, it was an ungainly device with two large, flat wooden boxes containing simple copper coils, five vacuum tubes and a few assorted components. The Metallascope soon captivated the imagination of the country, and within a short time, the world.

In 1936 Fisher Labs moved to a small building at 745 Emerson St. in Palo Alto to meet the growing demand for the Metallascope, which was nicknamed the M-Scope. Shortly thereafter, Dr. Fisher was granted a patent for his invention. The M-Scope became the accepted standard for all types of electronic metal detection. Geologists used it to locate ore, treasure hunters found treasure, utility companies pinpointed buried pipes, lumber mills detected metal inclusions in sawn logs and law enforcement uncovered abandoned and hidden weapons. In 1939, just prior to World War II, Fisher moved to an even larger building in Palo Alto at 1961 University Ave. During World War II and the Korean Conflict, Fisher Research Labs was called upon to contribute its technical competence to the war effort, but the M-Scope business was never neglected.

In 1961, Fisher Labs moved again to an even larger production facility in Belmont, Calif. By the time Dr. Fisher retired in 1967 his name and work had left an indelible mark on the electronics history. The company continued to grow, and in 1974, Fisher Research Labs moved to Los Banos, Calif., where it resided until 2006 when it was acquired by First Texas Holdings Corporation. Since 1931, Fisher has been the most trusted name in metal detection. Whether you are locating buried utilities, in need of security walk through metal detectors or want to find long buried treasures, Fisher technology will find it fast. From analog to digital, in single or multiple frequencies, Fisher quality and innovation are your reliable source for underground locating equipment.
