Don't need much to get started looking, a pan, some digging tools and a snuffer bottle, you don't actually need a snuffer bottle but they are awfully handy for around 3 bucks. You can worry about sluice boxes and all the other stuff later, first thing you need to learn to pan like a pro to work down sample pans as fast as possible, you can practice in a tub, use two similar sized pans you put one at the bottom of the tub as a "safety pan" pan out your material directly above to catch the tailings to re pan. Research is key to finding gold rich spots to investigate, seek out where gold has been found before in your target area.
