i'm looking to purchase one of these detectors. from what i can tell comparing price and coil type they are a close race.i'de like to hear from acual feild users of both and see your likes and dislikes about each. it seems to be that learning the numbers on the f2 would be better for target id. or can the ace 350 do just as well learning tones and symbols?i mostly hunt dirt and some areas have alot of trash even above ground. i have a cheap detector that is not name brand and i won't bash on it because is does detect, just seems poor on the mid and high tones.
