As the heading says, what's the best device/product for detecting detting ? I realise products like Link/Motec etc can do this, but as I'm not really planning on spending £000's for this, I was looking for a specific product. KnockLink has been mentioned to me in the past, but I wonder wether it would give false alarms if too much background noise was present.

Comments/suggestions ?

 

Seem to work well enough - they do filter out other noises - they're just damn ugly!!!
