I Laser Rangefinders
I.2.2 Accessories
The Criterion 300 and 400 laser rangefinders can be used in four
ways:
As a handheld instrument
As a handheld instrument with a shoulder rest (stock)
With the optional yoke and unipod. The unipod includes a
bracket onto which your datalogger may be clipped
With the optional yoke and a tripod
For most GIS data collection applications, the Criterion rangefinders
are a little too heavy to be carried in one hand, and it is difficult to
operate both a datalogger and handheld laser together. It can also be
difficult to accurately sight on distant objects when supporting the
laser by hand. The best compromise between portability and
operability is usually the yoke/unipod.
I.2.3 Cabling for Use with the Asset Surveyor Software
The Criterion 300 and 400 laser rangefinders can be purchased with an
optional download cable. The download cable connects to the
Criterion’s battery, and leads to a 7-pin connector.
The 7-pin connector is cabled as shown in Table I.1.

The 7-pin connector is then plugged into the data cable (P/N 32287),
which can be plugged directly into one of the ports on your TSC1
datalogger.
