The best thing you can do at this point is research, get permission for land, explore, have fun, and don't have high expectations. If you can do all those things, you will make incredible finds. It takes a while to get back in. It also takes a while if you move or change areas, because you must do all the research and make all the contacts over again. I found tons when I lived in Virginia years ago. Then I moved to KY and got busy, got out of the hobby for a while. When I started researching and hunting again it took several years to find my niche, and after I figured it out, I hunted hundreds of spots that no one had ever detected before, finding some fantastic things. When I moved down to Louisiana, I had to start over and it took me a full year to figure out where my niche was, do my research, meet owners, get permission, and spend many hunts exploring in order to find sites. Since then...well...you'll just have to look at my year end wrap up post later today to see how I've done.
Keep at it.
