NorCross®Sonic-Laser®Scale SP
Instruction Manual
The Sonic-Laser Scale has an accuracy of plus or
minus 3%. Therefore, it should only be used as a
guide to estimate a fish’s length. If the fish is close to
the legal size regulation in your fishing area, it is rec-
ommended that you use a tape measure or flat meas-
uring board to ensure that the catch is of legal size.
Safety Information:
• Read the following safety information carefully before
attempting to operate this scale.
• Only qualified personnel should perform repairs or serv-
icing not covered in this manual.
• Periodically wipe the case with a dry cloth. Do not use
abrasives or solvents on this scale.
• Do not store in a high temperature environment (auto-
mobile, vehicle or boat dashboard, direct sunlight, etc).
• Want to save yourself hours of aggravation? If so,
then read this manual entirely before attempting
the installation and/or use.

IMPORTANT:
To obtain accurate length readings the Laser pointer can not
have anything blocking it from touching the solid surface that
the tail of the fish is touching. If necessary, slide the laser
pointer away from the body of the scale to give the beam a
clear line of sight.
Trying to obtain length readings over a non-solid surface
(carpeting, choppy water, grass, weeds, soft sand, etc.)
may produce inaccurate readings. The area must be flat
and solid for at least 1 square foot (.3 Meter) around the laser
beam. You MUST hold the scale steady while using the length
measurement feature.
THE LENGTH MEASUREMENT FEATURE WILL NOT
FUNCTION PROPERLY IF THIS IS NOT FOLLOWED.

AUTO Mode
The "AUTO" feature is used to calculate the weight and length
of the fish and review the results upon completion.
1. Press “ ” button until “AUTO” is illuminated and “WGT” flashes
on the LCD.

3. Once a steady reading is obtained, press and release “E”.
4. “LGT” will flash on the LCD.
5. Hold the fish’s tail so that it barely touches a solid object (boat
deck, ground, dock, calm/flat water, etc).
6. Press and release “E”.
7. “WGT” will flash on the display along with the weight of the fish.
