General LDM1

INTRODUCTION
Thank you for purchasing General Tools & Instruments’
(General’s) LDM1 50 Ft. Laser Distance Measurer. The
LDM1 is designed to replace a conventional tape measure
in the hands of both DIYers and professionals.
The LDM1 works by shining an invisible infrared beam on a
target, which reflects the beam back to the tool. The time it
takes the beam to return is proportional to the distance to
the target. A red laser pointer is used only to aim the beam,
and not to carry any information. The LDM1’s range of 50
ft. makes it suitable for most indoor measuring tasks and
many outdoor jobs as well.
Why is the LDM1 better than a conventional tape measure?
• It’s faster. It takes much less time—and only one hand—to
hold the tool against a wall, aim at the opposite wall and
press the button than it does—requiring both hands—
to secure one end of a conventional tape measure, walk the
other end to the far wall, write down the reading and retract
the tape. The longer the distance to be
measured, the more time saved. Using the laser, the average
measurement can be made up to 10 times faster than by a
tape measure.
• It’s more accurate. Thanks to precision optics, the LDM1
can measure the distance between any two points more
than 10 inches apart with ±1/4 in. accuracy and 1/16 in.
resolution. It’s impossible to get that level of precision from
a tape that can bend or sag. What’s more, it’s much easier
to read the LDM1’s digital display, which can be held at eye
level, than to read a conventional tape measure whose
position may make tiny hash marks hard to see.
• It’s safer. Because the LDM1 can measure distances from a
distance, it takes the risk out of routine but tricky tasks. For
example, it makes it unnecessary to stand on a stepladder
and reach to measure the height of a ceiling.
WHAT’S IN THE PACKAGE
The LDM1 comes on a blister-packed card along with two
“AAA” Alkaline batteries.
