Attempts to use Phonefind technology were unsuccessful due to issues with them being able to activate location services on their phone. Visual references were used to orientate them and directions were given to walk a fence line to a stile where OS Grid Reference could be obtained. Having a confirmed location enabled the call handler to issue further instructions and provide a direction of travel back to a familiar point. Once back on a familiar path they were able to self extricate off the mountain to their vehicle.
