Only indirectly - sensitive and audio alarm - but not very good for accurately pinpointing the source of the radar...maybe others will confirm this?
What I really wish for is an RTE - the McMurdo or was it Pains-Wessex was a good idea but perhaps too big and expensive for the leisure market - if it had been c.£400 and more "petite" then I reckon lots of us might have forked out - that is, if it really did work!
