The Source Finder Mode
The Source Finder Mode allows the unit to lo-
cate an isolated source. In this mode, the unit
will start clicking if the unit is near radioac-
tive material. As you move closer to the radio-
activity (or farther away), the unit will click
faster (or slower).
For best results, aim the top of the unit at the
suspected source of the radiation.
The Rate and Dose modes are active when the
Source Finder Mode is enabled. This means
that you can read the higher Rate or Dose
without exiting the Source Finder Mode.
