Just lookin for some input on purchase.first,I have a 705 which is a great machine. But I always hear about fbs finding deeper coins,and that's what I'm after.all the houses I hunt are from 1800s to 1930s.here's my dilemma,I can get a se pro with warranty for the same price as a e Trac that's older.I think they're close in performance from what I read,just lookin for input. Thanks
