Fisher Gold Bug

The Gold Bug is one of the most respected VLF gold platforms ever built, and the reason is sensitivity: it runs at 19 kHz with a genuinely quiet threshold, which is what lets it hear sub-gram nuggets that other machines never register. Manual ground balance handles mineralized soil properly, and the low weight matters when you are working a patch inch by inch. It doubles as a very capable relic machine, since the same sensitivity that finds small gold finds small non-ferrous.
