Navigators need to understand the use of the equipment and its limitations. The accuracy of navigation using GPS is only as good as the equipment, which needs to be suited to the task. Before leaving for trips, leaders should acquaint themselves with and become proficient in the use of the GPS if they are intending to place any degree of reliance on this equipment. More importantly, they must have a sound knowledge of map reading and navigating without the use of GPS, for reliance on any one piece of equipment could be disastrous.
