[size=large]... The Ace 250 DOES have a concentric coil.robert roy said:Fisher has come out with the F2 (an entry level machine) and while it is more sensitive and pinpoints better because it uses the concentric coil and not the elipitcal like on the Ace, It is still not quite up to snuff.

The physical shape of the housing is elliptical, but the internal Transmit & Receive windings are of a concentric design. Concentric and wide-scan (Double-D) coils can be housed in round or elliptical shapes. Personally, I don't have a problem pinpointing with the Ace 250, and generally in the center of the coils axis ... IF the target shape and position is favorable to such a task.
