G'day Mates.
I'm new to detecting. My goal is to become a professional GOLD detector, but I'm experienced enough in life to know that isn't where a bloke typically starts. So to get some immediate detecting experience under my belt, complete with camping and overnight expeditions starting in May-August 2018, Here's the plan:
In my region of the USA: Minnesota, Wisconsin, Iowa, North Dakota, and South Dakota (We call it the 5 state area), there are hundreds of abandoned ore and taconite mines in Minnesota, and some gold mines in the Dakotas, dating back to the early 1900's. Moreover, there are THOUSANDS of abandoned properties from that same era containing old broken down homes, cabins, sheds, etc.. My intention is to get owner permission to search common areas like walkways, porch entrances, old outhouse locations, mine entrances, etc. SPECIFICALLY detecting for old Copper, Nickel, and Gold coins.
That said, the ground in those areas are typically a sandy and/or black soil surface from about 1/8 to 1/2 meter down, then turning to a mix of small gravels and larger rock up to a meter. In some cases however, it will be small gravels straight away. In the areas I'll be searching, I wouldn't think i'd have to dig more than about 20 - 40 cm. However, in those old outhouse locations, up to 2 meters could be possible.
Being my own back yard contains all of those above mentioned conditions, that's actually where I'd start, probably clearing a 5 meter x 5 meter area, then burring a few coins and earrings at different depths for practice.
So... given all that information: What's the best Hi-Tech detector that can be bought in the USA that's perfect for that job?
P.S. Money is less of a concern, but I'm a prudent person, so if cheaper is just as good... I Just want to buy the absolute best tool for the job, without too much overkill.
