Directional radio signal finder with attached fluid filled compass. The compass has an adjustable prism attached to it for added accuracy when reading the frequency adjustment appears to range from 200 kc/s to 400 KC/s and above that there is a setting for "Heron DF Aerial" I'm not sure whether this item works or not but the compass is certainly working and is very accurate, there are no breaks or damage to the cable so it may possibly be ok.

Item will be very well wrapped and boxed for shipment via Royal Mail, thank you.
