I have a new Minelab Safari and I am having a problem finding some old military buttons. My friend has a souped up older White's Eagle, no matter where we go, or who we are with, he consistantly finds more than anyone. We have been to a local historic site four times in the last month, he has found about 20 military buttons dating between 1804 and 1825, I have found one. However, my one and only button is extremely rare, AY30 in Albert's button book, with a rarity of 100 in the book. That button is worth $500-750 according to Mark Parker. Even though I have only found one button, I am just not sure what I am doing wrong? He is finding buttons all around me and I am finding nothing. I am using the coin mode, and occasionally drop down to the coin and jewelry mode, I have tried in automatic sensitivity, high sensitivity, and low sensitivity and not much helps. I have also used a special program I got online where you delete all the iron bars in coin mode, with the cursor, then save it to relic mode, which now turns all iron into high tones and all non-ferrous into low tones, that didn't work. On our way home today we were wondering if maybe the detector is discriminating out the buttons, although they seem to fall within the coin range numerically. I really did not try the relic mode, but was wondering if maybe this was the mode I should be using? I have over 160 buttons from this site, but in the last three outings with the Safari have just found one button, but that was a "banner" find on another site. Any ideas or help?
