Apologies if there are any recent posts in this topic, but what is a considered high quality metal detector and what is the cost range? Weekend type use on rock/clay/sand soil.
I would recommend that you start your search by checking out the Garrett "Ace" line of MD's. Great quality for the price, and the prices won't bust the budget. Obviously you can spend more if you like, but the Ace line offers a lot for the money, and are perfectly suited for your stated needs.
Still rocking my Fisher CZ-5. Not sure how many coins, gold rings, musket balls, and civil war buttons we found on our place but it sure is a lot of fun. I know they have better technology now I'm sure but I'd be hard pressed to test it out. I think I paid 800 for it in the 90's and I'm sure you can get it for a fraction of that now.
