Depending on the model of your structure sensor you may experience different use times. Both the Mark II and Mark Pro models have smaller batteries than the original Mark I model. Because of this, some customers have experienced shorter use times. For some older scanners, some may find that the scanner doesn't hold a charge at all. Here are some steps you can take to help with battery issues.

  1. Be sure to unplug the scanner from the iPad while it is not in use. The scanner will continue to drain power while plugged into the iPad.
  2. Keep the scanner on its charger while not in use.
