I have updated my software on my Equinox 800 to the new 3.0 update, This adds the 4KHz option. Make sure you keep the metal detector turned on and connect the usb charger to your pc and just follow how i did it on this video.. took 5mins to do.
I found it hard in the UK to find the 3.0 update so i have shared the link below.
