I used to do a lot of metal detecting. Got too busy, etc. and stopped. Recently retired and want to get back in pursuit of buried items. My old machine (don’t laugh) is a Relco Frontiersman. I bought it new when I was about 13. Worked most of the summer to buy it. It served me well, for what it was. My question, what is a good quality, starter unit these days. I see on-line adds but would like to hear from actual users. I’d like to spend less than $250. Thanks
