Bosch DLE 40 laser rangefinder: description, specifications and reviews

The place of the traditional construction tool comes more and more perfect and efficient devices. The category of measuring devices in terms of technological advancement is most indicative. Developers create easy-to-use and accurate goniometers, thermal imagers and self-leveling instruments. But the most popular and at the same time simple device in this range is the range finder. The Bosch DLE 40 Professional demonstrates an example of a high-precision and ergonomic digital roulette with which it is possible to measure both in a small construction site and in the construction of large-scale industrial facilities.

General information about the model

Despite the high demand for universal and multifunctional measuring instruments, the German manufacturer decided to follow the classic path and created a rather interesting rangefinder model. The device is positioned as a professional and in the same unusual approach. The fact is that the device Bosch DLE 40 has limitations on the range, but it provides high accuracy in calculating distance and area. That is, on the one hand, the device can be considered as a household model, but on the other hand it has enough opportunities for exploitation in professional needs.

As for the restrictions, the limit for measurements is noted in the name itself - up to 40 m. But the calculations are accompanied by a modest error of 1.5 mm. The final result of the Bosch DLE 40 laser rangefinder provides in different metric systems, among which are meters, inches and feet. Interesting and the body of the device, which has a rubber coating, which protects the electronic stuffing from damage. In general, the range finder is compact, equipped with convex buttons and a liquid crystal display.

Specifications

The main purpose of the device is to perform measurements of the distance from one object to another. Actually, the technical performance of Bosch DLE 40 is oriented to the qualitative realization of this task, which are presented below:

• The number of reference points is 2.
• Range of measurement - 40 m.
• The class of the laser element is 2.
• The error is 1.5 mm.
• Dimensions - 100 mm in height, 58 mm in width and 32 mm in thickness.
• Weight - 180 grams.
• The wavelength is 635 nm.
• Power is provided by four 1.5 V batteries.

If the rangefinder is selected specifically for professional tasks, it should be borne in mind that the model is the youngest in the family of Bosch measuring equipment. This means not only a relatively modest maximum in the length of the measurement, but also a lack of additional possibilities. For example, the electronic roulette in this modification has no built-in sight and does not provide a function to recheck the results.

Device Features

Like all Bosch instruments, which are in some way at the junction of household rulers and professional series, this model has absorbed the best qualities from both segments. For example, as well as high-end devices, the device received reliable external protection. The master can use the device in any conditions, not being afraid that the slightest blow will negatively affect the accuracy of the measurements.

To professional skills Bosch DLE 40 can be attributed and high speed metering. Depending on the complexity of the operation and in particular the distance range, the processing time takes from 0.5 to 4 seconds. Again, the presented results will be highly accurate. At the same time, the model was developed taking into account the ergonomic requirements of the modern builder. The device has a simple and convenient interface for management, which allows the instrument to be successfully used not only by specialists, but also by home masters.

Additional equipment of Bosch DLE 40

As an add-on, the company provides for the device to be supplied with rechargeable batteries, means for charging them, tripods for convenient positioning of the laser and reflectors. The most interesting thing for many is the last accessory. Reflective plates are used to expand the operating range. Thanks to the provision of such a component, electronic roulette can calculate several meters further and, most importantly, do not depend on the quality of lighting. Also worth noting security tools. Since the laser beam of the device can damage the retina of the eye, it is advisable to use special goggles during the work process.

Positive feedback on roulette

The main operating characteristics cause a lot of flattering reviews about the model. First of all, this is accuracy. Even against the background of other professional devices, the described range finder produces correct calculations regardless of the application conditions. In addition, many users note the versatility demonstrated by the laser roulette of Bosch DLE 40 when solving different tasks. It has already been noted that the 40-meter distance for the professional apparatus is an average value. But even models that work at 70 and 100 meters are not always able to maintain the same quality when processing results at small-distance distances. According to the owners of this device, it effectively manages and calculates distances of less than 10 m.

Negative feedback

The first place in the list of shortcomings can be put all the same truncated functionality, but, again, if compared with the leaders of the segment. In particular, users complain about the lack of lighting and lack of sight. True, it is the lack of these additions that explains the modest dimensions and convenience in handling the Bosch DLE 40. The price of the model is about 7 thousand rubles. On the Russian market, which many people are also perplexed. Similar opportunities are available in nominal value for many Chinese devices worth about 3-4 thousand. But, on the other hand, it is still not possible to compare these offers on the accuracy of data and reliability with German products.

Conclusion

The model demonstrates a rare example when the manufacturer seeks to master a not very popular segment, offering a truly high-quality device with a narrow specialization. Balanced technical parameters make the Bosch DLE 40 laser rangefinder an optimal solution for construction builders. The device can be used both indoors and outdoors. In the first case, the user can count on maintaining high accuracy even in spite of the non-standard for the rangefinder nature of the calculations - at a short distance. As for the natural environment of the device (in the air), the accuracy of measurements is noted here both in sunlight and in conditions of poor visibility. However, experienced stoics do not recommend the use of rangefinders in conditions of severe frost or at high air temperature.
