CHOOSING YOUR LASER RANGEFINDER: INSTRUCTIONS FOR USE

The laser rangefinder is used by both construction professionals as well as outdoor sports enthusiasts such as hunting or golfing. At present, many models are available on the market. So how do you make your choice in this vast market?

What you should know about rangefinders


A rangefinder is a device that makes measurements with great precision. Most models are equipped with class 2 laser with a wavelength of 635 nm. It is a harmless device unless it is directed to the eyes as it can cause great retinal damage. Therefore, it is imperative to use it in accordance with the usual safety measures. As far as performance is concerned, the laser range finder can measure long distances up to 250 m. Its operating principle is quite simple. The laser is projected onto a target and the light is reflected back to the camera. The telemeter then calculates the phase shift that occurred during the projection. Thus, an exact measurement of the distance is obtained. Rangefinder Club It is necessary to use laser rangefinder in works for construction and real estate. Previously, models equipped with infrared and ultrasound were used but their precision was inadequate. Today, laser rangefinders can make measurements with precise and sharp results. As an indication, the entry-level models make it possible to measure surface, height and volume. In general, the maximum distance limit for this category of laser rangefinder is 80 m. These entry-level laser rangefinders are for indoor use. They allow many carpentry works to be made as well as to easily fit a room, because the place of the furniture is already calculated. The professional models of rangefinders are suitable for outdoor use. They have in fact performances designed to meet the needs of architects and site supervisors. In particular, they make it possible to measure unevennesses such as the inclination or the height of a staircase. The ranges of professional laser rangefinders are generally longer than those of entry-level models, as is the higher accuracy level due to long distance calculations up to 250 m.

Essential features in a telemeter

Many criteria must be taken into account before buying a range finder and features are an essential part of it. The most important are: the electronic tilt sensor or a bubble level that indicates whether the rangefinder is perfectly horizontal. This will not distort the measure. There are also other constants that make it possible to calculate both the length, the width as well as the height. In addition to the surface, it is immediately possible to calculate the volume. In addition, a good laser rangefinder must be able to take several measurements as a result, a little more than one per second in order to radiate on the opposite acute angle and select only the longest measurement. For general technical specifications, the choice of a laser rangefinder depends on its weight, the type of power supply and its dimensions. It is therefore important to know that a laser range finder is powered either by AA type batteries or by a Lithium Lion rechargeable battery for more autonomy. The second option is therefore more suitable if the device is intended for professional use. On the dimensions, the laser rangefinder must be practical to use and transport. The choice must therefore turn to ergonomic models, which fit easily in the hand. For this purpose, the hull of certain rangefinders is covered with a soft grip coating that adheres easily to the touch. Weight is also a factor of maneuverability not to be neglected. It should be light enough to not tire during use. Beware of laser rangefinders that seem light at first but that earn a good 100 grams once their
