PLEASE READ THIS FIRST:
Your choice of the SONIN COMBO PRO shows
you are a professional who demands quality and
value from your tools. Please take a few minutes
to read this manual. Your SONIN COMBO PRO
has many easy-to-use features that will make your
measuring tasks faster and easier once you
understand them.
The SONIN COMBO PRO is actually two measur-
ing tools in one. It can take measurements by
bouncing sound waves off flat hard surfaces such
as walls or ceilings from 1 ft 6 ins (46cm) up to
60 ft (18m) in the
SINGLE UNIT MODE
or
from 3 ft (1 m) up to 250 ft (75m) by sending
infrared light signals to the
Target
(included) and
receiving sound waves back from the
Target
in
DUAL UNIT MODE
.
Use the
SINGLE UNIT MODE
primarily for
indoor measurements or whenever you are
measuring to a suitable, hard, flat surface, less
than 60 ft (18m) away.
Use the
DUAL UNIT MODE
when you need
to measure distances greater than 60 ft (18m),
when there is no suitable surface to bounce the
signal off of, or when there are obstacles partially
blocking the measuring path. [ If you can see the
Target (and it is within range), the COMBO PRO
can take a measurement. ]

Most accurate
mode
. Useful in environments when obtaining a
stable reading can be difficult. Validates all
measurement before displaying. Filters out noise
from machinery and other sources.
