    Comparison of laser levels, levels BOSCH GLL 3-80 P and ADA 6D MAXLINER

    What is – modern and high-quality laser level, level. Certainly looking telecast about the repair, many paid attention to the laser devices by which erected walls, mark the position of decorative elements, put tiles and so on.   d. These devices are called laser levels (leveled). They can be quickly and precisely produce any markup. The cost of these levels is not high, and almost anyone can afford to buy such a tool. The choice is huge. But when it comes to professional use, you pay more attention to the functionality of the device than its cost.

    This review focuses on two professional laser level: BOSCH GLL 3-80 P and ADA 6D MAXLINER. Let's get acquainted with them closer.

    Packaging equipment:

    BOSCH GLL 3-80 P is packed in a cardboard box. Just want to note that the GLL 3-80 P has eight options for configuration. The truth is the main difference of about half of them only a possibility to place the unit in the L-BOXX (inserts of different sizes). Because really useful accessories are: laser receiver, tripod BS 150 P (although its maximum height to 147 cm), universal mount BM1. True if the price tag is considerably grows. For comparison we have chosen the most budget equipment: laser level, batteries, insert a   L-BOXX (with an additional compartment for the receiver of the laser beam and brackets under it), cover for the device, laser target. More complete instructions are weighty in many languages ​​and quality certificate. The box pictures with examples of the application of standards and recommended accessories. Cardboard boxes, though busy, but with the active use at the construction site for a long time it will not be enough. It is worth considering the additional costs for the acquisition of the case.

    BOSCH GLL 3-80 P, as previously mentioned, not in the richest set. However, this is the bare minimum for indoor use: laser level, cover to be attached to the belt (a controversial option, considering its size and weight), magnetic target. The target can be mounted on a metal surface or mounted on a hinged leg.


    At ADA 6D MAXLINER one option configuration packaged in a cardboard box with colorful photographs and brief characteristics. Inside the box is a square plastic case with aluminum edges and snap lock for carrying and storing the device.   In the case of cellular rubber lodgements to secure the device and accessories. With this briefcase can already do not fear for the integrity of the device on site. It includes level, battery, charger, laser target, laser glasses and screw extension. This equipment richer the comparison BOSCH GLL 3-80 P. difference: more opportunities Nutrition (charger and batteries) and laser glasses for better visibility of the laser lines in bright light. But on the street in bright sunshine with a set of the same will not leave.  

    In the photo on the right depicts a set of actions which included a tripod-Rod ADA Silver.


    Flat housing   BOSCH GLL 3-80 P made of quality matte plastic. Level with the body shape comfortable to stand along the walls. The rear of the device is covered with a rubber grip for sure. Top, front and side windows rendered laser emitters. Top is also a keypad control. The red release button is on the side. At the bottom is access battery compartment and two metallic thread for mounting: 5/8 and 1/4 inch. There are V- neck positioning level, but none of the beam through the cut-out passes. At the ends of the recess are magnets. Their purpose is not explained so well in the instructions. Attach them to the metal device can not be too heavy. Yes, and in front of the window projecting laser interfere.


    Housing ADA 6D MAXLINER made for a different scheme. The device looks like a spaceship: a cylindrical housing of glossy plastic on the metal base with sharp leveling feet. Plus this design are two: the installation and alignment on almost any surface (rough screed slopes) and   fast and accurate guidance of the vertical beams. Control panel with bubble level located on top of the device. The three horizontal and four vertical beams are arranged on the side of the window casing. There's also the switch-lock battery compartment and a connector for the charger.

                          That is, you have the choice of power supply. The level can run on AC or battery. Dead battery does not become a problem.   At the bottom is an endless micrometer screw and digitized degrees limb. The bottom of the base and leveling feet located attachment hole 5/8 inch. It is also a window for the laser plummet down. To carry the laser level on the body-fixed soft grip belt.


    Operating Range:

    20 m without receiver and up to 80 meters from the receiver operating range   BOSCH GLL 3-80 P

    10 m without receiver and up to 100 meters from the receiver range of work   ADA 6D MAXLINER

    Both laser level work with the receiver of the laser beam. When used operating range is greatly increased. Since both sets are designed for use indoors, then compared their laser beams for these conditions.

    The parameters of the laser beams can be estimated from photographs. In the first photo the distance to the wall 1, 2 meters. The thickness of the vertical line of the BOSCH GLL 3-80 P visually thinner: a little more than 1 mm from the   ADA 6D MAXLINER — 2 mm. But the Rays ADA 6D MAXLINER   brighter.



    Fig. 1

    A horizontal beams (Fig. 2), the reverse situation. Only the   ADA 6D MAXLINER beam is the same 2 mm, and   BOSCH GLL 3-80 P beam is wider: a little more than 2 mm, and there is a bundle of the beam. This deficiency is often seen in this type of laser emitters. With that it can only be eliminated by replacing a new one.

    Fig. 2

    The third photograph (Fig. 3) a distance of 6.5 meters.

    Fig. 3

    The vertical line BOSCH GLL 3-80 P looks dimmer than the ADA 6D MAXLINER. The thickness of the beam is almost unchanged: 2.5 mm for both models. A horizontal beam again summed (Fig. 4). We   BOSCH GLL 3-80 P it dull and blurred, and the thickness of the beam is larger than that   ADA 6D MAXLINER: Almost 2 mm to 1.5 mm. It is impossible to determine exactly, since the edge of the beam blurred. Apparently this is a marriage in the manufacture of the radiator.

    Fig. 4


    Accuracy BOSCH GLL 3-80 P: & plusmn; 0.2 mm/m (or 2 mm/10 m).

    Accuracy ADA 6D MAXLINER: & plusmn; 0.1 mm/m (or 1 mm/10 m).

    Accuracy BOSCH GLL 3-80 P 2 times coarser. Time alignment of the pendulum in both models is quite fast and does not exceed 3 seconds.

    sweep angle rays :

    Scan-rays at the instruments is almost identical. The horizontal beam is closed: 360 & deg ;. But vertical rays at the   ADA 6D MAXLINER are not closed at the bottom, unlike BOSCH GLL 3-80 P in which both the vertical beam 360 & deg ;. Vertical plane of each unit two. As both models have pitches up and down and four in a horizontal plane. Only the   BOSCH GLL 3-80 P lowest point plummet - the cross, and at   ADA 6D MAXLINER — dot. Lines can be turned off, leaving only the necessary work.

    Different scanning beams at the instruments by the design of the laser emitter. The BOSCH GLL 3-80 P used emitters which the laser beam shines on the top of the cone polished. In this way, we obtain a closed laser line. This allows you to use a smaller amount of laser emitters to create closed lines: only one against three (ADA 6D MAXLINER). The downside: not possible to adjust the prism and on the Convergence   at the BOSCH GLL 3-80 P weak point: the angles of intersection of the laser lines can be far from ideal 90 & deg ;. Because no quality polishing cone prism often a bundle of lines. The   ADA 6D MAXLINER mixture of classic radiators with adjustable cylindrical prism.

    In terms of guidance vertical rays   ADA 6D MAXLINER much more convenient   BOSCH GLL 3-80 P. If you turn the devices on a table can be without too much inconvenience, then going on a tripod   ADA 6D MAXLINER much more comfortable than in the management of BOSCH GLL 3-80 P. Have micrometer makes the vertical beam pointing quick and easy. Rotary   digitized limb will help to establish the vertical beam at the calculated angle.

    The deflection angles from the vertical state:  

    - BOSCH GLL 3-80 P — 4 & deg ;, ADA 6D MAXLINER – 3,5 & deg;.

    Signaling the limit deviation from the different devices.

    The     BOSCH GLL 3-80 P — Flashing lines and audio signal from ADA 6D MAXLINER -   Only flashing lines.

    Also in the BOSCH GLL 3-80 P mode has tilted (inclined markings, such as stair railings fortified wall).   At ADA 6D MAXLINER such a regime there.


    Laser Level   BOSCH GLL 3-80 P, as previously mentioned, can be mounted on a tripod and mount with 1/4 and 5/8 inch. And a tripod mount for this set will have to choose on their own.

    ADA 6D MAXLINER can be fixed only on the thread of 5/8 inch. But now on sale there was a set which includes the tripod rod ADA Silver. This solid rod is assembled from five sections made of aluminum. Crepe she thrust between floor and ceiling and can reach 3.6 meters (range of working heights from 10 cm to 3.6 m). For the finishing works in the standard urban apartments or private homes that is enough. The device attached to a rod with a movable plastic pad. It can be moved up and down and rotate around the rod. That is, the laser beams can direct any   point of the room. This post can be placed anywhere: in the middle or in the corner of the room.

    Very convenient addition to professional laser level. The price of the device does not change.
