My buddy has been using an Advantage for a few years and has tried nothing else. I let him try my Equinox 800 and I had doubts he would like it. I was surprised how easily he took to it. I showed him the settings and off he went detecting with it. His first target was a silver ring. He ended the day with the silver ring, wheat penny, silver dime and a V nickel. He loved the Equinox 800 and now he has one.
I don't think someone with little or no experience would do well with the Equinox. I think a simpler detector would be better where you can set the disc and dig when it beeps. Get some experience detecting and if they like it, then move up with a better detector.
