How it differs from its neighbors

At 71 kHz, the Gold Bug 2 is listed for gold prospecting alone. Its modes are Normal, Audio Boost and Iron Discrimination, with no display or target ID listed. It weighs 2.9 lb and lists up to 35 hours on 2 x 9 V.

Fisher's F75 works at 13 kHz on a larger BiAxial DD coil of 11 inches, with a 0 to 99 target ID scale. At 3.5 lb, it weighs 1 lb more than the Gold Bug Pro. It is rated for 40 hours at most, on 4 x AA (not included).

Same cover for both. Each Gold Bug carries a warranty of 2 years, and the F75 gets 2 years as well.
