This refers to the range finder measurement accurancy.The Market rangefinder measurement accuracy generally is ±1 m. Aite Different models have different measurement accuracy, and measurement accuracy range is ±0.5 m~±1.5 m.Better accuracy, offer user more accurate data and experience.
Pin Seeking Function: to flag 250m
AITE Pin Seeking Technology is used to measure the distance to the nearest target (first target priority). This function will help you easily to find out the pin distance especially when have a hard hand-shake or there are many objects in the background.

The principle of telescopic rangefinder and its key points of selection
Telescopic rangefinders usually use the pulse method to measure distance.The pulse method works as follows: the laser emitted by the rangefinder is reflected off the object to be measured, and is then received by the rangefinder, which simultaneously records the time of the laser round trip.Half the speed of light times the round trip time is the distance between the rangefinder and the object being measured.The accuracy of the pulse method used to measure the distance is usually about +/- 1 m.In addition, such rangefinders typically measure dead zones of about 15 meters.
Points of selection
1. The basic parameter of a telescopic rangefinder is to measure distance.First, you should choose a telescopic rangefinder that needs to measure distance.
2. Measurement accuracy. The nominal measurement accuracy of all manufacturers is +/- 1 meter, which is only theoretical data.The measurement accuracy depends on the target environment, telescope rangefinder lens, infrared laser emitter quality and data processor accuracy.
What are the different classifications of laser ranging sensors?
There are two types of laser ranging sensors: triangulation and time-of-flight.There are three types of time-of-flight laser ranging: pulsed laser ranging, phase-based laser ranging and interferometry laser ranging.
Pulsed laser rangefinder technology takes advantage of the fact that the laser pulse energy is relatively concentrated in time and the instantaneous power is very large (usually up to watts). In the case of cooperative targets, pulsed laser ranging can achieve edge measurements, and universal pulsed laser ranging sensors can measure distances of tens or even tens of thousands of kilometers, achieving accuracy of more than 10 centimeters. When performing a range from a few kilometers to dozens of kilometers, the distance measurement can be performed only by diffusing the signal to the pulse tube using the measured target, even if no cooperative target is used.The disadvantage is that the absolute ranging accuracy is not very high.
The phase laser ranging sensor USES the high frequency sinusoidal signal of fixed frequency to continuously modulate the luminous intensity of the laser source and measure the phase delay generated by the modulating laser back and forth once.The measured distance is calculated by phase delay.
Phase-based ranging measures the time of signal propagation indirectly by measuring the phase delay of the continuous amplitude modulated signal propagating back and forth over the distance to be measured so as to obtain the measured distance.The method has high measurement accuracy, usually at the millimeter scale.
The interferometric ranging method is also a phase ranging method, which is different from the general phase ranging method in that it does not measure the distance by measuring the phase of the laser modulated signal, but by measuring the distance by measuring the change of the interference fringe.
