Does the discrimation control have any control on it?

[keith777]

not sure what you mean.
was hoping someone could tell me weater you are able to see the diferance with the sensitivity settings wilst air testing or not.
at the moment i can't seam to get the sensitivity knob to make any differance in depth.
