See email from John Norman who bought one of the Loc8tors to use as a model finder.
Test results disapponting, Bill. Put tag at end of our garden behind a privet hedge. At a distance of approximately 30 metres the device only indicated a ‘find’ twice out of six attempts. It just isn’t reliable enough for our purposes. At a distance of 8 metres it finds every time. The suppliers claim a much greater range – over 100 metres – and I expect in ideal circumstances this can be achieved but our circumstances are unpredictable, aren’t they?
So cross that one out, then. Probably the only reliable systems are the expensive ones used by the free-flighters.
