In VFR flight, nothing should distract from lookout. A device like this has added risk of a false sense of security. Not for me, not even as a back up aid.
Ah yes, the visual waveband receiver, requires certification every two years or less depending on age, hopeless at tracking a moving object with no relative motion, generally lazy and unreliable but in its day all we had. Of course it wouldnt be certifiable today but lives on with grandfather rights.
