What is it?
A rangefinder is a direction tool that helps users to judge distance, based on laser beams that reflect off distant objects along the way. It measures the overall amount of time it takes for those laser projections to leave the device and come back, thereby giving the user an approximation of how far or near they are to what they are targeting.

When using these devices, it’s important to note that sensor readings may sometimes be affected by environmental factors and reflectivity coming off the object. Similarly, if there’s an obstruction in your line of target, you may struggle to focus on the item and this can affect accuracy levels.
How to Operate a Rangefinder?
It’s important to follow the correct procedure when using a rangefinder so that it can give you the most accurate results. Below are some of the steps you should consider:
a) Adjust the eyepiece angle to make the target clearer in your line of focus.
b) Choose the range mode and use the reticule function to increase or decrease magnification
c) Continue pressing onto the mode button for a split second, so that the object distance reappears again to give you more precise readings.
d) Calibrate the settings so that your device can cope with the environmental conditions present where you are, which may be fog, rain or light showers.
e) If measuring distance in hilly terrain, the digital 7x rangefinder shall automatically compensate for gradient inconsistencies, in order to estimate precise readings of the linear direction your laser beams should follow.
Factors That Affect the Accuracy of These Devices
While most rangefinders operate using the same basic principle, whereby beams bouncing off far objects are measured using an inbuilt high-speed clock to estimate distance. There are certain factors that will determine the accuracy of your readings, some of which include the following:-
a) Receiver aperture dimensions. This refers to the size of the receiver optic piece, which is responsible for capturing return readings and relaying the information to the sensor for the final display. A huge aperture has an equally greater impact on how much incoming data the device can process, plus it allows the device to perform exceptionally well at far off distances with superior accuracy and precision levels.
b) Magnification quality. The camera lens is responsible for providing magnification in rangefinders. There are two types of lenses found on these devices, which are the binocular and monocular versions. Typically, the first option provides greater levels of laser magnification, but they are also much heavier and expensive compared to monocular rangefinders.
c) Availability of multi-pulse technology. While older rangefinder models simply rely on the initial feedback coming off the sensor, modern versions use multi-pulse technology for analyzing results, whereby 100s or even 1000s of tiny laser pulses are fed back into the system over a very short duration of time. The device then gathers a large sample amount of readings, which are delicately analyzed to remove any obstructions such as fog, rain or brush that may otherwise affect results before the final data is presented.
To summarize, the laser rangefinder is a useful tool used to find direction and measure the distance across vast landscapes. It works by releasing beams to the target object and calculating the time period between going off and coming back to determine distance.
