To accurately calculate the surface plane and future dimensions foundation or other construction objects, use levels. They allow you to correctly set the coordinate axis on the ground, regardless of the evenness of the soil topography. Among the varieties The most affordable models are optical models, where a specialist needs to look into the eyepiece and calculate the level planes on a graduated scale. Here are some of the most popular and proven products from this industry that experts have found.

BOSCH GOL 26 D + BT 160 + rail GR 500
Experts awarded the first place to optical construction level from Bosch. This is a 36mm device capable of enlarge image up to 26 times. Thanks to such power it will turn out to measure distance to 100 m. The minimum focusing for calculation starts at 30 cm. Optical sight is able to calculate height, flatness of the plane and angles. Judging by the reviews, this is very solid level, assembled efficiently and without play. He length measures accurately and performance in 100 m more than enough for most construction sites. All adjustments carried out smoothly and without excessive effort.
The product came in first place for a complete set. In the set there is a reliable level, a tripod with an adjustable reach of legs, bag-case on a belt that protects the optical device from shock when transportation. In addition, the manufacturer applies aluminum level, capable of folding up to a height of 5 m.
- quick change in tripod height;
- it is convenient to rotate micrometer screws;
- a clear horizontal dial scale.
- some tripods 160 cm will be low;
- does not have verification from state control (initially when selling in store);
- in cold weather, hands freeze from the aluminum strip.
The second place is occupied by a level with a 36 mm lens and the ability to approximations up to 24x. The device is equipped with a durable case that protects optical device during transportation. From the store the goods are already comes with a certificate of verification and can be immediately applied to work that builders like in reviews. Minimum measurable the section starts from 20 cm, and the error does not exceed 2 mm per km. The rangefinder weighs only 1.85 kg, so move around the object with it’s not difficult. Japanese manufacturer attaches to product instructions in Russian and adjustment tools, but a tripod and strap will have to buy separately.
The level is recognized as the best in quality of work in difficult conditions, for example, when there is vibration on the soil (nearby works heavy equipment) or a strong, gusty wind blows. Optical the device is equipped with a sensitive compensator that takes into account emerging tilt of the tripod and provides image stability with preservation of the plane.
- light weight 1.85 kg;
- durable case in a set;
- verification certificate attached to the product;
- the accuracy of measuring horizontal angles is 1º.
- first you have to aim at the mark through the front sight;
- high price.
Leica NA332 (840383)
The level from the Swiss brand is designed to work with temperature from -20 to +50 degrees. Optical tube equipped 36 mm lens, but enlarges the image up to 32 times. Wherein distance measurement error not more than 1.6 mm. Product Dimensions They are 30x20x20 cm and it weighs 1.5 kg. The model is already listed in state registry and is accompanied by a certificate of verification. Supplied goods in a plastic case that protects the lens of the lens when transportation. Judging by the reviews, surveyors like Enlightened optics for good visibility in conditions rain or fog.
The main advantage of the level is a lifetime warranty from manufacturer. Although the optical device is already in the lead in view of Swiss quality, but such manufacturer obligations inspire full confidence in the work of the level.
- verification certificate is attached to the level;
- the optical system is well protected from light;
- clear marking on the scale;
- light weight 1.5 kg.
- high price;
- the screws slide slightly in the hands.
Condtrol 32X (2-3-047) with tripod
The level stands out from the above due to the optimal a combination of cost, functionality and configuration. The model has a price 3-6 thousand rubles. lower than competitors, but at the same time supports enlarge picture up to 32 times. Magnetic inside compensator, and the kit comes with a tripod, case and telescopic rail with millimeter scale. Vizier is here optical, which facilitates aiming at the target. Error is not exceeds 1.5 mm. Minimum measured area starts at 60 cm.
Experts considered the optical level to be the best due to the increased lens diameter of 38 mm. It provides increased light penetration and guarantees better visibility. We recommend the product especially for construction sites, where to display coordinate axes and lay planes required at distances 100-120 m.
- average error of 1.5 mm;
- optical sight;
- 32x magnification;
- entered in the state registry.
- sold without a certificate of verification.
BOSCH GOL 20 D Professional (0601068400)
Optical rangefinder suitable for measuring distance at construction sites with a length of up to 60 m. With its help you can Perform leveling III and IV class. Under this category excavations of points of ditches, reference level marks foundation, determining the locations of the design laying of piles, columns, plates and farms. A specialist can easily perform it grid breakdown or tracing. Error here slightly superior to the above optical models and is 2.5 mm. The housing of the level has a water protection level of IP54 and its operation is permitted in the rain. Optics designed for application at negative temperatures up to -10º C.
This is another level that has established itself well. thanks to the precise operation of the compensator. If the plane to be built deviates from the horizon, the optical device itself aligns image in the range of ± 15º. A crosshair is used for this. a grid of filaments passing through a target beam acquiring horizontal position. Another advantage of the product is the price, more affordable than analogs.
- compensator operation within 15º;
- the possibility of increasing to 20x;
- attractive price;
- fast lens 36 mm in diameter;
- permissible operation at a temperature of -10 degrees.
- 2.5 mm error greater than competitors.
RGK N-32 (4610011870071)
The optical model is made with a 32 mm lens, which is capable of zoom in to 32x. Minimum focal length starts from 30 cm, which allows the use of the level even in cramped mines, tunnels and basements. The device is suitable for construction sites with a length of up to 100 m. The accuracy of the readings is deviation up to 1.5 mm per kilometer. But to use the limb is not very convenient because of the closed scale, which can only be watched through a small window. Weighs a level of 1.7 kg and is equipped plastic storage box. Surveyors praise the clear picture of the optical system and lack of twitching Images.
We considered the level to be the best due to the case with increased protection. Its tightness is at IPx6, which allows it to work optical device, not just in the rain, but even in direct strong jets of water. Another manufacturer allows you to use level at temperatures up to -40º C, which makes it one of few suitable in the Far North. Next Advantage is a guarantee for the goods 25 years.
- strong plastic box;
- large and convenient screw for adjusting focus;
- minimum working distance of 30 cm;
- Magnetic damping is applied inside.
- the sight has a front sight, which is less convenient than optical option;
- You can see the limb only through a small window.
