Have an exterra 70 with 3khz and 18.75 coils. Hunt primarily old farmsteads which have an abundance of iron. Have the ability to pick up a new etrac with gift cards with no out of pocket cost(can't swing a ctx just too much money). Will the etrac running in ttf be much more effective in the heavily iron laden sites I hunt over the exterra? Would keep the exterra to cherry pick then move to the etrac and work slow to pick keepers out of the iron. Also use the exterra in wood tot lots with 18.75 small coil to pick out gold jewerly(seems to work well). Maybe the etrac would also work well running a jewerly program in these areas? Any info and advice would be appreciated. Happy New Year to All!!
