If you are on the fence and want to invest in a detector that would have a wider range of benefits for you both in Arizona and Alaska I would suggest adding an Equinox 800 or preferably the 900 to your arsenal. This will allow you to hunt the trash-rich areas with a bit of discrimination and will still work very well on tiny gold. It is impressive to see how deep these detectors find targets and how small of bedrock gold they will find.
