Went out to a new field that I just got permission for. Had my Explorer Se pro and the AT pro with me. Got off at 1:30 and it was 65 degrees so off I went. Started out with the Se and dug an old pocket watch back, then a complete pocket watch. Soon after that I dug a wrist watch back. Well I fugured it was time. Grabbed the AT and got the Merc right off the back. 1916, no mint mark. Dug the two buttons soon after. Only covered a small part of the field so will be going back. Videoed the hunt so i'll post it when I get it done. I will say I really like the AT pro. Just alot of fun to use. ( Pro mode, zero, iron disc at 25 ) I'd like to know more about the cross rifle insignia if anyone has any info.
