The Minelab Eureka Gold was introduced in 1998 and was discontinued in 2017 after a 20 year run. The Eureka Gold has been replaced by the new Minelab Gold Monster 1000. The Minelab Eureka Gold for a long time was the only nugget detector that allowed you to change frequencies with the flick of a switch; 6.4, 20, and 60 kHz, all using the same coil, unlike the Minelab X-Terra units. This made the Eureka Gold one of the most versatile VLF gold prospecting detectors available for handling different ground conditions.
 
The Eureka Gold 20 kHz mode is used for most detecting for great all-around performance. The 60 kHz mode is used in low mineral soil looking for extra small nuggets. The 6.4 kHz mode is used in extreme mineralized soil that would overwhelm most VLF detectors. The Eureka Gold is a good choice for someone hunting areas with widely varying mineral conditions. Weight including rechargeable battery pack 5.3 lbs. The control box may be chest or hip mounted removing most of that weight from the operators arm. It comes stock with a 5" x 10" elliptical DD coil. Four accessory coils are available for the Eureka (Minelab and Coiltek).
 
The Eureka Gold with its three selectable frequencies will handle a wider range of ground conditions than most other VLF detectors. For a 60 kHz detector, it  lacks the edge of the Gold Bug 2 or GMT when it comes to the smallest nuggets. This is because the 60 kHz mode is not the native operating frequency of the Eureka Gold but a harmonic offset of the main frequency. The Gold Bug 2 and GMT are dedicated single frequency units designed specifically around their respective operating frequencies. The best setting on the Eureka Gold appears to me to be the 20 kHz mode, as the detector seems optimized for this frequency. You will generally lose depth in the 60 kHz mode and so this mode should only be used for small shallow gold.
 
The 6.4 kHz mode on the other hand is more of a fallback frequency only for situations where the 20 khz mode is proving ineffective due to hot rocks of ground interference. 6.4 kHz is simply too low a frequency to be effective on small gold nuggets but can help penetrate highly mineralized ground to find larger gold nuggets.
