No,just the stock,from the factory beach mode.It picks up all us coins including all clad,indians,(not sure about flying eagles as I do not have any to test),lincolns,all nickels,dimes,quarters,halves and my Morgans including Large cents and tokens.Descriminates most of the crap that we don't want like nails and ferrous trash.It also hits large iron.I tested it on all of my colonial relics including my shoebuckles and it worked like a charm.I put a bunch of different colonial buttons under the coil to test them as well and they all hit like a coin signal,loud and clear.This is the mode that I also use in the old cellar holes and it has worked for me there as well,with great results.I'm primarily a coin hunter but love digging up the old buttons and all the other goodies associated with early america.I run auto sensitivity+3,fast recovery,heavy trash and ground difficult.For these types of sites the beach mode works for me.
