It's worth it if you're doing the course with a reputable company or operator. There are a number of things they would teach you about finding gold legally and successfully including using your detector and staying safe in the bush, a good course will probably teach you as much in 3 days as you would learn in 3 years if you don't have exeprienced friends to guide you.
I was thinking of the Leonora course. Some guys from the Adelaide Detector club have voiced an interest in doing a course next year.
That's Tony and Lisa, aka @Goldtalk Leonora here on PA. A top couple from all I've heard/seen - check out his excellent videos here:
My partner and I did the course with Goldtalk Leanora and I highly recommend it
I attended Goldtalk Leonora a few years ago and it was amazing. Then spent a few weeks on leases they had access to. Well worth the money and effort. I drove from Northern NSW.
