Rating of TOP-14 laser rangefinders: review and characteristics of the best models

What to look for when choosing a laser rangefinder

Rangefinders presented on the modern market differ not only in design and cost, but also in functionality, as well as technical parameters.

Here's what you should pay attention to when choosing them first:

• Measuring range. The maximum value of this parameter is decisive regarding the scope of application of the device. For measurements in apartments or private houses, a range of 20 meters is sufficient. It is easier to measure large rooms with a 40 m gadget. A range of 100 meters or more may be required when working in open spaces and in very large rooms.
• Error. A defining characteristic of the reading accuracy of a particular model. Laser rangefinders usually have this indicator close to 1-2 mm. Depending on the model, the reference point may be the front of the device, the hinged bracket, the tripod mount, or even the rear panel.
• Laser color. This parameter is determined by the laser length. Laser technology usually works with green (535-550 nm) or red (635-650 nm) beam. The human eye sees these colors best, with green being slightly better.
• Nutrition. Laser rangefinders are equipped with their own energy source. For short-term work, a device with a set of batteries is suitable. For long-term and active use, it is recommended to choose a battery model.
• Functional. Modern laser rangefinders can do a lot more in addition to the basic measurement of distance to an object. Depending on the model, these are measurements at two or more points, determination of the level or angle of inclination, calculation of the area, photography with overlay of measurement results, etc.
• Protection. Like any construction tool, a laser rangefinder is exposed to various adverse factors, including dust, moisture and temperature changes. When choosing, you should pay attention to the protection class of a particular model (IP) and its operating temperature range.

Types of rangefinders

Based on the principle of operation, rangefinders are usually divided into:

• Laser;
• Ultrasonic.

The first type of tape measures uses a laser beam reflected from the surface to take measurements. The distance is calculated based on the phase shift of the signal modulated by the beam. Such devices are highly accurate and can be used both indoors and in the field. The disadvantages of laser rangefinders include their sensitivity to bright sunlight, as well as the inability to measure the distance to transparent objects, such as windows. In this case, it is recommended to use a target, which manufacturers usually include in the package.

Ultrasonic tape measures work on the principle of echolocation. They measure distance based on the reflection of a sound wave from an obstacle. The disadvantages of such devices include less accuracy. The fact is that the sound wave travels quite widely and can be reflected from different surfaces, which affects the result. Another advantage of laser rangefinders over ultrasonic ones is that the former are designed to work over long distances. However, the advantages of ultrasonic tape measures include the ability to work with transparent objects, as well as insensitivity to sunlight.

The TOP includes laser and ultrasonic rangefinders. Models were selected taking into account technical characteristics, cost and reviews from customers and craftsmen.

Peculiarities

When working with a laser rangefinder, it is advisable to take into account some features of working with this device.

Rangefinders have the ability to take measurements at different distances and with a certain error. Thus, the maximum distance can range from 60 to 200 meters, with an error of 5 cm. These data are indicated in the product passport. Most rangefinder models operate within the range from – 10 to + 50 degrees.

When operating the device outdoors, you must remember that weather conditions play an important role. Performance may be reduced in both poor and sunny weather.

Key Features

When taking measurements, it is necessary to eliminate obstacles that may arise between the device and the object, this could be foliage, glass, etc.

The practice of using laser measuring instruments has led to the emergence of certain operating rules. For example, the measurement result will be distorted if the beam is directed at a highly reflective surface (mirror, foil). The result will not be entirely correct if the beam is directed at an object with low reflectivity (tar paper).

To obtain extremely accurate results, use a special device with a reflective surface.

During operation, it is necessary to constantly monitor the condition of the batteries. Weak current sources also negatively affect measurement results.

It is advisable to use a tripod when taking measurements. In this case, the measurement accuracy will be increased.

The best inexpensive models

Despite the low cost, the presented models will not only successfully replace a construction tape, but will also allow you to calculate volume, area, angles, and perform other measurements.
