My MXT did a great job at the campsite of Ole Andy, finding a cuff button at about 6" and two buckshots in different holes at about 7-8". All 3 readings in relic mode indicated "button". The buckshots were larger than Civil War bucks. These were about 3/8" in diameter. Other, larger buttons were also found by others. None of these are for sale, however. I'll post a picture when the finds are clean enough to photograph.
