metal detectors

I don’t have much activity today. I just went to the church together with my housemate then go home right after the church service. We were planning to go to the mall and buy some groceries but I was not feeling well. I felt so weak and tired. I am not sure if I am having flare-ups with my rheumatoid arthritis or not. After coming home I went to sleep for half an hour then woke up and surf the web and read anything that interest me. I was able to browse a website about metal detectors. I didn’t know that there accessories that we can add to metal detectors.
