Completely portable so you can easily go on the field (with athletes) or go from room-to-room without the hassle of the cord.  Most popular of the two models.  INCLUDES:

1. Wand
2. Three batteries for portability
3. Base Recharger Unit
4. Large case (for entire system)
5. Small Portable Case (for wand only)
6. Two goggles

Very affordable except it's not portable due to a cord requiring you to be near the base unit.  No batteries included with this model.  The laser properties are exactly the same as the Portable Model.  INCLUDES:

1. Wand
2. Corded to base unit
3. Carrying case
