New Child Mode – While the measurement is being taken, a melody plays continually to keep children’s attention.
A constantly changing color display, both on the outside and inside target the device,
also keeps children involved during the process.
Automatic Axis Compensation and extended measurement range – Not only does the device let the examiner know the cylinder axis angle, but it can also automatically compensate if it is not level. Measurement range has also been expanded.
Lightweight and easy-to-hold grip
Improved battery life – At 180 minutes, the battery capacity is now twice that
