Rangefinders, optical and laser instruments that measure distance to a target for survey, golf and hunting.

Laser rangefinders must meet laser safety class rules and may be export controlled; state range and accuracy. Measuring and survey instruments are precision goods: pack in padded cases with silica gel, state accuracy class, range and resolution, provide calibration certificates traceable to national standards, CE/BIS marks for electronic units, and keep lithium batteries under dangerous goods rules; some navigation and geophysical instruments are export controlled.
