I believe its a Detech coil. I just wanted to know if the target sounds are the same with the concentric. How about the duration of the signal length of tone etc...On some of my other detectors I can tell if I have a coin sized target by the size of the tone but I'm having trouble on the Etrac. I can tell the size by pinpointing with the Etrac but not from the original tone.
Thanks,
