The SEM unit is very well suited to this, as long as there is only ONE
distinct noise source. I have both the SEM and the 1026 and a friend has
the ANC-4 unit (not tested yet) but the SEM beats the 1026 for ease of
finding a null, hands down. Many times a null couldn't be found on the
1026, with the same combination of antennas on the SEM, it took only a few
seconds to find a null.  Too bad the SEM unit is no longer in production,
as far as I know. If you can get one, I cetainly would.
