Well I finally got to an old site to use my new F75 LTD. I found 2 Large cents one 1845, the other not able to get a date off of. Also found to flat buttons. Found iron, an old buckle. One of the reasons I got the F75 is because my hearing is getting bad, so I cannot hear certain tones or pitches like I used to. I wanted a machine that could give me clues other then sound. Well the F75 did just that. I am very happy with the F75.
