• Aims at the object you want to measure with its laser point 
• Measures a straight line from 0.91m to 18.288 meters
  (acceptable range)
• Error appears if the distance you measure is beyond the acceptable range
• Foot or Meter measurements selectable
• Screen light for easy reading under poorer lighting environment
• Auto-off mode if no operations for 4 minutes
• 3 memories allow you to record the length, width and height of
  the room

• Converts these measured data into area or volume

• Addition and subtraction function allows you to do some simple
   calculations

• Uses 1 x 9V Alkaline type 6LR61 Battery
