Looking for help in making a purchase on a detector. I live in the northern plains and will primarily be searching for coins on old abandoned country school sites and abandoned farmsteads. I currently have a whites 2000d that I have had since I was a kid 30+ years ago(it’s not great). I haven’t ever done much serious detecting and now my kids are old enough to take interest in this activity, so we’ll probably be going out to get some exercise and find treasures. I don’t want to spend more than I need to, but also want to get what makes sense. I would like recommendations on 2 detectors. Best detector under 600 and best detector under 1200. My youngest kid received a 45 dollar detector as Christmas present and has really been fired up to get out and test it. Things finally melted and dried out, so we went out for the first time yesterday and found a bunch of nails and other trash. We were searching a farmstead that has been uninhabited since 1930. We also found a pretty neat piece off a cast iron stove that had very legible stamping on it. It read “prize Bismarck no9” burdett smith co. Troy Chicago. Thanks for any recommendations
