During a good and high-quality repair, and even more so in construction, a rangefinder will serve as a necessary tool for measuring the distance. Of course, you can use a regular rigid ruler or a longer and more flexible tape measure, but their inconvenience is that you need to measure by dividing the distance into segments and applying the instruments to a hard surface. And even so, there will be errors.

Using a laser rangefinder, it is possible to measure long distances with the smallest error - only 1-2 mm . Also, the measurement itself will require less time, since for the process you only need to press one or several buttons and on the instrument display, and you're done.

One of the firms producing laser electronic rangefinders is the Chinese company SNDWAY . The official website of the manufacturer is presented in Chinese, the instructions for the devices are in English, so we will consider the most popular models in this article.

The lineup

In popular online stores you can find the following models of SNDWAY laser rangefinders, which are quite budgetary and differ from each other in different possibilities:

• SW-T40, SW-T60, SW-T80, SW-T100;
• SW-M40, SW-M60, SW-M80, SW-M100;
• SW-S50, SW-S70;
• SW-600A, SW-1000A;
• SW-T4S 40;

SW-T40 is a laser rangefinder without a reflector, the minimum measurement distance is 5 cm, the maximum is 40 m, the measurement accuracy is 2 mm, it has the ability to save up to 30 measurements. It has a bright display backlight with well-readable black characters on the screen, as well as sound indication and an auto-off function, which significantly saves battery power.

Besides the usual measurement, the rangefinder includes the functions of Pythagoras, addition, subtraction, calculation of volume, area and continuous measurement. Battery powered. This model weighs 110 g. There is a bubble level on the side of the case. The durable plastic case is waterproof and dustproof, and there are seven buttons on the front that are easy to press even with gloves on. From the presented line of rangefinders from SNDWAY, it is the most budgetary.

Ideal for DIYers.

SW-T60, SW-T80 and SW-T100 - identical models to SW-T40. The only difference is in functionality. This is the ability to measure distances up to 60, 80 and 100 m, respectively.

SW-M40 - laser tape measure, which is very convenient to use for measuring distances. Measurement range - up to 40 m, measurement accuracy - 2 mm. It has the ability to save up to 30 measurements, perform calculations according to Pythagoras, add and subtract measurements, calculate the volume and area. Power supply is also from batteries. Compact, lightweight tool that fits in your pocket. The body is made of durable plastic, protected from moisture and dust. The housing has a built-in bubble level for even more accurate measurements.

Models SW-M60, SW-M80, SW-M100 absolutely identical, the only difference is that the measurement length is 60, 80 or 100 m.

SW-600A, SW-1000A - models that are mainly used in the construction of roads and telecommunications, since they have the ability to measure distances up to 600 and 1000 m. This digital rangefinder is best mounted on a tripod, since when measuring, you need to aim through the eye. There is a zoom function for greater accuracy. Power is supplied by a lithium-ion battery, which is charged from the mains.

SW-S50, SW-S70 - models equipped with a color display with a black background, symbols here are clear and large, which makes it possible to see them even in bright daylight. There are more buttons on the body than the previous models - there are ten. This digital rangefinder has the ability to measure up to 50 and 70 m. The measurement accuracy is 2 mm. Also, the model has a sound indication and an auto power off function. The body is shockproof, has a tripod thread and a built-in bubble level.

The embedded software can perform not only measurements, but also the following calculations: Pythagoras, volume, area, addition and subtraction, calculation of angles, determination of maximum and minimum values. The roulette is powered by batteries.

SW-T4S Is an inexpensive, affordable laser rangefinder that has the ability to take measurements both indoors and outdoors. The set includes a reflective plate and a cover. The body is made of hard plastic and the rubber buttons are easy to press. Power is supplied by batteries. The display can show four lines, it is backlit. The device measures up to 40 m. Software functions: measurement of minimum, maximum, continuous measurement, addition and subtraction, calculation of volume and area, Pythagoras function, trapezoid measurement. The built-in memory is designed for 30 measurements. An auto shutdown is also provided.

User manual

You can take the SW-T40 model as a basis, as other models basically use the same buttons.

• Red button labeled Read turns on the device, this button is also responsible for enabling the "Minimum" and "Maximum" functions.
• " +" And "-" buttons are responsible for the addition and subtraction of both measurements and already calculated volumes and areas.
• Drawn cube button denotes the functions of calculating area, volume, diagonal measurement, inaccessible line and inaccessible height. To select the desired calculation, you need to successively press this button.
• Floppy disk button recalls the last measurements.
• U button changes the point of the report, and when the button is held down, the units of measure are changed.
• Off / Clear button when pressed quickly, it resets the last value, and when pressed for a long time, it turns off the device.
• Sometimes you need to calibrate the rangefinder . To do this, turn off the device, press the Off / Clear button, then quickly press Read. After that, the display will show Cal, and already with the buttons "+" and "-" you need to set the correction.

Reviews

According to user reviews, SNDWAY rangefinders are one of the most budgetary devices on the market, they are quite functional, fast in the speed of measurements. The compact body is easy to handle and use, there is a bright readable screen. Another plus is that most models have a built-in bubble level, which greatly facilitates the work, since it can be used to make measurements more accurately. The auto power off function is also convenient, which allows you to save power if the user forgot to turn off the rangefinder.

When using area calculations or according to Pythagoras, prompts are displayed on the display, which is a big plus if there is no instruction at hand.

Of the minuses, it is noted that the paint from the keys is quickly erased, in addition, not all models have a tripod mount. The instruction is only in English, so you have to look for operating rules on the Internet. Also, the downside is that the power comes from batteries, which should be changed from time to time. Some other buyers find the plastic case uncomfortable, while other companies have a rubber case that sits more securely in the hand.
