General

Key features

The LASERTAPE FG21-LR is an extremely compact, durable, high performance laser rangefinder for handheld use. Protected by thick rubber, it is ideal for use in harsh environments. Look through the 6x30 sighting optics at almost any arbitrary target. At the push of the trigger button, the LASERTAPE emits pulses of eyesafe laser light toward the object. The LASERTAPE then calculates the distance to the object based on the time taken for the reflected light to return. Distance and inclination are displayed in large, easily legible digits in the sighting optics typically in less than one second. The FG21-LR offers 0.2 m accuracy over 2000 meters reflectorless. Use a reflector to increase the range by a factor of 5.

A powerful short-range suppression feature facilitates reliable use in bad weather conditions such as heavy rain, snowfall, or fog as well as measurements through a window.

  • Reliable semiconductor- laser rangefinder technology

  • Display of the strongest target
  • Adjustable short-range suppression for measurements under bad conditions (dust, rain, fog...)
  • Built-in inclinometer for height measurement of objects and for horizontal path length calculation
  • Display of the measured data within the sighting optics field-of-view
  • Sighting optics' crossed hairs are coaligned with the measuring beam
  • Built-in buzzer, which can be switched off for soundless operation
  • Built-in standard batteries or accumulators "AA"-size
  • External power supply 12 V DC
