So I am supposed to be saving money for something important in August and I have been studying prospecting a little bit being as the area I moved my family to in northern Arizona is a mile from an old gold mine. I'm on a pretty tight budget and $630 is a lot of money for me to take a chance on something but I decided to anyhow. I bought a garret gold master 24k detector. I'm pretty confident in at least making the money back that I spent on the detector by August. I'm disabled and have a good amount of free time. Was this a risky move?
