Instrumentation mankind enjoyed for centuries. We built the pyramids of Egypt, the Taj Mahal, Wall of China - and it's all thanks to measurements of geometry. Naturally, XX century promoted the sphere of human life to a new level. Today we have laser rangefinders, which allow up to Nanometer determine the distance, carried out with the results of measurements mathematical operations and even build models.
In today's century, anyone can order such a device itself. But how to choose the right? On what parameters to pay attention, looking at the description of rangefinders in the shops? Let us examine in our review.

What is important when choosing a rangefinder
First of all, you need to understand - why you need a rangefinder. This device can be useful as well as in the repair of the bathroom, and when hunting elk. Rangefinders use golfers, architects, landscape designers and explorers, artists and rock climbers.
Pay attention to the maximum range of the device. If you want to align the suspended ceilings or even to put a tile, then the rangefinder for 50 meters, you will come up. For architectural and large-scale construction work will be enough of 150-250 meters. But fans of active sports and Spies better look at the premium rangefinder that "finishing off" at 500 meters and beyond.
Another equally important parameter - the instrument accuracy. Best Soup give up to 2 mm with a maximum error of using the distance. Ideally, such a measure should not exceed 1 mm at a distance of 50-150 m.
What else is important? In Russia, weather and operating conditions is always less than ideal. Therefore it is necessary to take into account, at any temperature working range finder. The lower range of operating temperatures of the device - the higher accuracy in the measurements in abnormal conditions. Frosts hit, and leaving in place already can be transferred to another day. If your device is not adapted to the low temperatures, of course. As well, when the device is protected at least at the level of IP54 against water and dirt. This means that he will not be afraid of splashing and rain, and dust can not seep into the smallest gaps plastic housing.
Separately, it should be noted the additional distance measuring function. Consumer devices usually do not sync via Bluetooth to a smartphone or not simulate the scene as a result of the measurement. However advanced Soup possess enhanced not only data, but also additional features until the velocity of the measurement object.
Our choice
Sndway SW-T40
For laser tape measure does not necessarily pay a fabulous price. Less than 2 thousand. rubles, you can buy a rangefinder Sndway SW-T40. Distance work he is small, only 40 meters. However, this will be enough to repair the apartment. Accuracy is also within reason - no more than 2 mm. Distance measurement when it requires no more than two seconds.
The memory Sndway SW-T40 can hold up to 30 different values. Special function can find in them the maximum and minimum peaks, calculate the height using the formula of Pythagoras. Few? The developers have added even illumination for working at night. Only operating temperature range can be attributed to minuses from 0 to 40 ° C.

Leica Disto D1
But the professional Leica Disto D1 instrument can withstand temperatures up to -25 ° C. The instrument in its characteristics is not much different from the SW-T40. Those working 40 meters, the same error of 2 mm. But what about the famous Leica label on the body?
D1 - the most inexpensive version of the entire Leica range. And if you're a fan and connoisseur of the brand is a good opportunity to join. Especially because the device works perfectly with Bluetooth and works with all mobile operating systems. The device reliably cope with the measurements in the harshest conditions. It is charged by two AAA-batteries. And it may take up to 10 thousand on this charge. measurements. Not bad, if you do not think about the price.

BOSCH GLM 120
If the "charged" you need a fully professional device - our choice BOSCH GLM 120. The device is somewhat similar to plump old phone. He also has a color display IPS-display that allows you to read figures in real time. But this device can operate at a distance of 120 meters with an accuracy of 1,5 mm and 0,2 ° when measured angles.
The device without any problems connected via Bluetooth or USB to smartphones and computers for data transfer and remote control rangefinder. Bosch made a separate application for the systematization of the measurement results and the allocation of the maximum and minimum values. In this case, the device is protected against dust and splashes according to IP54 standards, and therefore is ideal for use in harsh Russian reality.

Elitech LD 40H
By rangefinder requirements for easier home. Therefore, our best option for this category is Elitech LD 40H. Small appliance for 2 thousand. rubles can measure the distance to a distance of 40 meters with an accuracy of 2 mm. The rest - LD 40H is fully consistent with "classmates". It can measure angles up to 60 °, a monochrome display, stores up to 100 recent values. What other advantages are necessary? Is that the hand strap that manufacturers care put into the kit.

makita LD080PI
Another good professional device with the function of Pythagoras - Makita LD080PI. The device can operate at distances up to 80 meters, making it a welcome guest on construction sites, and not in small apartments. In addition to high accuracy (error less than 1.2 mm), fine Romanian rangefinder measures the depth and volume of the object in real time, using all the same formula Pythagoras.
LD080PI perfectly protected from external influences. In addition to the cover, which the manufacturer put in the box, it protects the body IP54 standard. Unfortunately, the model does not support synchronization with smartphones, which greatly simplifies the task of today. But for those who work in the old way this limitation may even be to the taste.

Working on the street.
In sunny weather, the bright light rangefinder can not catch the reflection of the laser, and the operator - to miss the point on the illuminated object. Therefore, some manufacturers are making rangefinder special glasses that allow you to monitor and mark the day. worth using dark targets or just black objects for accurate operation of the machine. However, not with all rangefinder that works and, if your device is not sensitive enough, will have to wait.
How to measure the area of the room?
If there is a range finder Pythagoras function, it can be in real time to calculate not only the area of the object, but its depth and height of two or three points. In addition, this functionality has a proprietary software manufacturer if rangefinder connected to a smartphone or computer.
