Choosing a tablet for surveying can be very bewildering because there is a huge range of models from many different manufacturers. The good news is that PocketSurvey mobile will run on ANY Android tablet or phone.
This is a brief summary of some tablets suitable for surveyors.
Bear in mind there may well be better and later models by the time you read this, because the industry moves so fast!
Note: If you prefer to use a phone rather than a tablet then you cannot go wrong with anything from Samsung or Huawei.
