The laser rangefinder is a handy tool for planners and designers. The product copes with accurate markings in all projections, identifies shortcomings, small nuances and sizes of parts. The tool will prove to be very relevant at the construction site. In this case, the device will show more accurate data than a tape measure or a ruler.

Features and purpose

The main functionality of an electronic device is distance measurement. The principle of operation of the technical means is simple: a light pulse that comes from a laser is reflected from a certain point. The distance to the point is calculated from the time taken for this reflection. The functions of modern rangefinders are diverse: calculating area, volume, and other quantities. In this case, all data received by the device are promptly fed to the receiving computer.

Laser rangefinders are presented in a large assortment on the market today. Particularly popular were the models of the manufacturer Bosch. They are even allowed for use in design government organizations and have received certification due to the high accuracy of the data obtained.

The exterior features of this Bosch laser tape measure resemble the outline of a conventional mobile phone. The rangefinder can be classified as a household grade equipment, as it is compact and easy to maintain. Appliances, by the way, are even divided into household and professional ones. The latter are distinguished by the presence of built-in memory, a special tripod in the kit, protection of the case from dust and moisture.

The perceived benefits of professional models are not always needed by amateurs in the field of architecture, design and construction. In choosing a device, the main aspect should be the tasks that the selected instance will be capable of. In household solutions, measurements of height, distance and tilt angles are sufficient.

Electronic "filling" simplifies the complex measuring process, but leads to an increase in the cost of the product. The software "filling" with a set of geometric formulas is often simply inaccessible to a common man in the street. The necessary calculations are still performed manually, not automatically. The technical features of the instruments include the following characteristics:

• possible beam range - 80 meters;
• laser wavelength - 635 nm;
• the number of points for the origin - 4;
• Li-Ion battery 3.7 V;
• weight - 140 g.

Additional features of some models include a rotary display and high-quality backlighting.

Selection Tips

Before buying a device, you need to decide on the purpose of its use. If you need something more perfect than a classic tape measure with a scale, a device with the characteristics of the Bosch GLM 50 is enough. It is distinguished by its quality indicators and is sold in stores in the middle price category. The functionality of the device is not very extensive, but for the most part this is not necessary for a common man in the street.

For example, the GLM 50 C already has great functionality and can be used in the construction and design sectors. The device is compatible with mobile devices, as well as with many professional programs. A specialist can easily draw up a project and immediately give it to the customer to evaluate.

Professionals are usually responsible for the choice of devices for work, so they pay close attention even to accessories. For example, a tripod will add comfort in working with a rangefinder. Amateurs also look closely at the device, because it will be convenient in the process of marking the personal plot.

Bosch BT 150 has the ability to aggregate with a tripod, which can be adjusted in height from 50 to 150 cm. The tripod is durable, aluminum, lightweight, inexpensive in stores. The mounting screw thread is usually standard. The equipment is equipped with a spherical level. The rangefinder will be installed strictly horizontally, even if the surface around is uneven. Professionals also wear special glasses when working. The cost of such products is low, and often they come with professional devices. For household devices with a laser beam, glasses are also useful. It is known that the laser can cause irreparable damage to the eyes.

Some Bosch household rangefinders are available with extended range options. This requires an additional reflector. The Bosch GLM 80 has this advantage. Although the initial technical and operational indicators are sufficient not only for domestic, but also for professional use.

Manual

Safety rules must be observed during any work. The recommendation points on the product packaging accompany every Bosch rangefinder. Inside there is also an instruction that requires detailed study.

The first item in it says: do not direct the laser beam towards the sun, as well as towards other bright light reflectors . Such actions will lead to distortion of the precision apparatus indicators.

It is undesirable to use the rangefinder as a level. To avoid damage to the interior, the manufacturer does not recommend using the devices in a humid and dusty environment.

If the device during operation moves from a minus temperature range to a plus one, time must be given to adapt to external conditions. It is worth considering the inaccurate correctness of the data obtained by the beam gap through colorless liquids (water) or objects (glass, film).

Errors in readings may occur due to the reflective surface of the object that has reflected the beam. It is recommended to wipe the device with moisture protection, which has got into water, dry it, and then continue working.

All users of rangefinders are advised to follow the rules of personal safety . The laser beam of most Bosch devices has a hazard class 2. The laser will not bring much harm, however it is forbidden to look into a direct beam, as this will damage the pupils.

It is also forbidden to work with the device through ordinary glasses. They will increase the risk to your vision, which can lead to temporary blindness. The Safety Guide does not recommend moving or removing labels from the product panel. Do not direct the laser beam at any person or animal.

The device is not recommended to be repaired or disassembled at home. It is better not to use accessories not intended for the rangefinder.

It is strictly forbidden to use the devices outside the limits specified by the manufacturer. It is forbidden to deactivate the system security settings. It is forbidden to take measurements on tracks and construction sites, as well as in other crowded places, for untrained persons.

Pay attention to the battery indicators when using. Three divisions are enough for about 100 measurements. It is recommended to replace the batteries later. It is better to pull them out when the device is not in use. The batteries must be inserted in accordance with the polarity indicated on the cover of the device.
