The segment of construction equipment intended for making measurements went far beyond the usual level and roulette. Distances, angles and deviations from surfaces today are measured by high-tech digitally controlled devices. For each function, you can find a specialized device, but more and more there are universal models that allow you to perform several actions. These include the Bosch GLM 80 Professional rangefinder, equipped with a laser pointer and designed for use in various fields of construction.
Model Overview
The model is a continuation of the concept of the DLE 70, which was intended to take measurements of distance, height and tilt angles. In the new modification, the functionality was significantly expanded, new options were added and the basic characteristics were increased. In essence, the Bosch GLM 80 can be considered as a rangefinder and inclinometer. But the most important thing is the electronic filling with a display that rotates depending on the current position of the case. This feature greatly facilitates the measurement process.
Of course, an increase in performance could not do without an increase in the cost at which the laser range finder is implemented . The price is about 9 thousand rubles. For this money, the user also gets the opportunity to conveniently make calculations through the angle sensor. Electronic filling contains software with a set of geometric formulas, according to which the necessary calculations are automatically performed.
Specifications
The device represents a line of professional measuring equipment, which was reflected in the technical characteristics, which are presented below:
- Range of action of a beam with a possibility of measurement - 80 m.
- The laser wavelength of the apparatus is 635 nm.
- The laser device category is 2.
- The number of points for the initial reference is 4.
- The standard measurement error is 1.5 mm.
- The device is powered by a Li-Ion battery.
- Voltage - 3.7 V.
- The mass of the device is 140 g.
- The dimensions of the device are 111x51x30 mm.
- Additional features - display rotation and backlight.
Technical parameters show that the device received good qualities in terms of opportunities for long-range measurements. This allows you to use the Bosch GLM 80 model in the construction of large-scale projects in the open. The only thing that can complicate the measurement process is the lack of a built-in sight and verification.
Rangefinder Features
In addition to a rotating display with the display of measurement results, the model also has a convenient keyboard with large buttons. For ease of physical handling of the case, the developers also provided soft pads that increase tenacity and prevent slipping. Compared to other laser devices, this device even works with surfaces that do not reflect the laser beam. That is, you can aim the device at glass structures without fear of getting the wrong distance calculation. It is worth noting the energy-saving options of Bosch GLM 80. The manual notes that the device automatically turns off if the user has not performed any actions with it within five minutes. This saves battery power, which can be replenished via a micro-USB cable. Also, using the same interface, you can connect the rangefinder to a computer.
Positive feedback about the model
Owners of the device note a successful combination of ergonomics, functionality and reliability. In the process of work, the case is easily held in hands and even in conditions of parallel execution of other work operations it does not cause any particular inconvenience. The main advantages that users note are the ability to perform primary measurement tasks. In particular, many emphasize the accuracy of the Bosch GLM 80 rangefinder with minimal error indicators, speed and convenient presentation of data through the display. In addition, the benefits of the sound alert feature are separately noted. As for reliability, then in this regard the model causes only positive impressions from the owners. The body of the device is not only resistant to mechanical damage, but also provided with a dirt-resistant coating, therefore it does not get dirty in close contact with building materials.
Negative reviews on the rangefinder Bosch GLM 80
There are no special claims to the device, but in some aspects of operation certain difficulties arise. For example, many users have problems calibrating the device, which must be done when large deviations in measurements are detected. However, the instructions on the display help to cope with this. There are also complaints about the lack of some functions. This applies to the scope and calibration options, which are available to non-professional models of such devices. Many are confused by the cost. Even taking into account the fact that the company offers a multifunctional laser rangefinder, the price of 9 thousand specialists seems overstated. On the other hand, if we take into account the wide operational capabilities of using the device in solving various problems, this investment can justify itself.
Conclusion
The functionality and ergonomic qualities of the device can be significantly improved if it is used in combination with additional devices. In particular, German developers offer reflector kits that increase the range. In addition, the Bosch GLM 80 rangefinder demonstrates higher measurement accuracy when used with a tripod support. Similar additions are also present in the manufacturer's line. The tool itself can be useful for performing almost all tasks related to measurements in professional construction. In this regard, Bosch has positioned its product in its segment. If we talk about domestic use, then a set of functions and technical and operational indicators with a measuring range of 80 m, most likely, will be unnecessary.
