I went to an old fort site yesterday with the modified IDX Pro and Bullseye coil.The fort was started in the 1880's and closed after WW II. The Parade Grounds have been used thru the years as a ball field. I've been hunting this site for about 15 years and have pulled a lot of silver, indians, wheats, tokens and military stuff from here. I hunted the old barracks site and then the parade grounds while my wife hunted for bottles. The Waltham pocket watch is 14kt. gold filled or plated? and the age? I found some similar ones on ebay that were from the 1920's but I won't know for sure until I pry the back off and check the serial number.
