レーザー距離計を使えば、遠くの的までの距離を正確に測れる。
With a laser rangefinder, you can accurately measure the distance to a faraway target.
Formed from 距離 (distance) plus the suffix 計 (meter, gauge), which appears in many instrument names such as 温度計 (thermometer) and 体重計 (scale).
COMMON COLLOCATIONS:
- レーザー距離計: laser rangefinder

NOTE:
In camera terminology, 距離計 refers specifically to the rangefinder focusing mechanism; such cameras are called 距離計カメラ (rangefinder cameras).
