To update the software on the Equinox 800, simply navigate to Minelab’s website. There is a section specifically dedicated to software updates. Find the Equinox 800 software page. Download the update on either PC or Mac (requires Windows 10 or greater than 10.13 High Sierra Mac OS, 50 MB of hard drive space, 20 – 30 MB of RAM, a 2.0 USB port, and Equinox USB charging cable with magnetic connector).  Once the update has downloaded onto your computer, plug your Equinox 800 into the USB port and apply the update. There is information on the Minelab website for exactly how to apply updates for anyone who needs further guidance.
