Note:

The Levelogger Junior looks very similar to the newer Levelogger Junior Edge. To determine the difference, look at the serial number on the body of the Levelogger. If the fourth number in the serial number is 1, it is a Levelogger Junior. If the fourth number is a 2, it is a Levelogger Junior Edge.
