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).
