Excellent, fully informed and when I had issues with dates nothing was too much to help me adjust timings to suit.
Strengths
Lots of information and quick responses to queries.
Improvements or suggestions
Maybe have a specific route onto the map. When leaving Ughab Rhino Camp the gps sent us in the wrong direction up the dry river bed which was deep sand for 10km's and an horrendous exit.
If we had got stuck in the sand the Hanes of another traveller passing was slim.
Suggest and offer a Satellite phone. In areas where you really needed it in case of abreakdown etc there was no phone coverage.
