Personally, I installed in all channels, though they don't help at all with my 8 - 20 kHz intermittent noise without degrading
my locating ability.

Yeah, if you can work without the filters do so, the system does appear to work better without them. I've got the chips in all four channels but only one is actually enabled. Of the three loops one is horizontal so doesn't pick up very much of the two nearby VLF transmitters, one is orientated for minimum pick up and the third rotated as far as I can get away with such that a 19kHz filter reduces the VLF transmitters to the same level as they are on the other two loops.
