Both the Equinox 800 and 600 are really great machines and operate about the same. There are some key differences between the two.
The Equinox 800 has a some additional features and more customizations.
Minelab Equinox 800
- Wireless Bluetooth headphones are included
- You can save your user settings so you do not have to set up again each time you power on
- There is a gold mode that is included which is perfect for gold prospecting
- You can operate in single kHz in both 20 and 40 kHz.
Minelab Equinox 600
- Includes wired headphones but has Bluetooth capability
- You cannot save your user settings
