Enhanced power for making measurements on site
Charging is reduced approximately one quarter of the time compared with conventional models. The detector supports a variety
of measurement orientations and can perform measurements up against a wall surface or while facing upward. When combined
with optional accessories such as a height gage adapter, the detector can perform measurements in various orientations and
settings.
