Detector Compatible Distance

[Bush]

Just putting out there.
Some time back some years ago a fellow was going to give feed back on how close detectors can operate together.
SDC 2300 running beside a GPX4500 or sdc 2300 running beside another sdc.
My guess two GPX`s would need vast distance between them again at a guess.
Any takers ?

These days you would be lucky to even find 2 GPXs working within 5km of each other
