I live in AZ, we have a lot of Hot Rocks and tiny gold. I've been thinking of getting a Gold Detector. I have narrowed it down to 3. Gold Bug 2, Gold Monster 1000, and the XP Deus 2. I'm a beginner, but would like to advance with the detector I choose. $1500 is the most I can go, even though a PI detector would be excellent. Any thoughts on this would be greatly appreciated.
