I'm not sure, as I don't have one, but the best way to figure that out is to pass a small coin like a dime over the coil and noting where it sounds. If the coil has to rings, it is probably both and you can try to verify this by passing the dime over at a slower pace. You just might hear it go off twice as it can be heard with the coil on my 250. If this were done with a quarter or larger object, at least on my 250 coil, you wouldn't get the double signal as easily because it's making both go off at the same time.

You have a transmit and a receive coil in the loop. The transmit coil radiates the magnetic field and the receive coil 'sees' the target. 8)

Outside ring is the TX which transmitts the signal into the ground & the inner circle is the RX which recive the signal back from the ground.
