Hands on with RedBack Lasers DGL1010GM Digital Grade Match Laser

DGL1010GM Digital Grade Match

The RedBack DGL1010GM has many outstanding features such as digital grade setting from remote, Li-ion power and millimeter display receiver.  But was makes it stand out from the crowd is its ability to automatically grade match.

Setting Grades

So what is automatic grade matching?   It is the ability for the laser level to automatically slope up or down and lock onto the height of the receiver on a particular axis.  The display on the DGL1010GM then shows the grade between the height of the laser level and the height of the receiver digitally.  Grade is displayed as a percentage to three decimal places.  This can be extremely useful in earth moving, drainage and general civil construction projects.

The RedBack DGL1010GM can also set digital grades on one or both axis up to 10%.   Simply by entering the required grade into the laser levels keypad or into the radio smart remote control.  Also included with the laser level is a fine adjustment plate and telescopic sight which allows quick and accurate alignment of the axis.  Making the grade setting process as accurate as possible.

The receiver supplied with the DGL1010GM is pretty special too.  Not only does it communicate with the laser level for automatic grade match but it also has a millimeter display.  The millimeter display indicates up to +45mm and -45mm above or below level and the level bar itself has 3 accuracy settings; =/- 1mm, 5mm and 9mm level bands.

More Features

Further Features of the RedBack Lasers DGL1010GM include V-W-S which is Vibration and Wind Settings.  Normally with electronic self levelling lasers if once rotating vibrations are detected the laser will stop rotating adjust level and start rotating again.  On a windy day or near heavy machinery these small adjustments can become so frequent that working becomes difficult. With V-W-S activated, the DGL1010GM continues to rotate during these minor adjustments.  The laser level will, however, still stop rotating after major disturbances.  Another feature is TILT, this is like tilt on a pinball machine.  If the laser has a major vibration or someone kicks the tripod by accident the laser will stop rotating.  It will not re-start until you tell it to do so.  TILT is a warning that something has changed and you may want to re-check you datum before continuing.

Vertical Operation

The DGL1010GM can also operate on its side for vertical alignment and site layout applications utilising the side mounting plate.  When on its side the rotating beam is now vertical and at 90 degrees to this is a laser dot and a site square can be accomplished.  To do this is to electronically aim the dot laser to a target left to right by pressing and holding the grade/slope arrow button. The longer you hold the faster the dot moves.

  • Place datum marker over the datum point marking the conjunction of the 90 degree lines.
  • Roughly align laser housing so dot is striking target point along the one line of the 90 degrees, then use the direction buttons to electronically fine tune this alignment.
  • Once the dot is on the target use the receiver to pick up the rotating line on the second line of the 90 degree. Your square is now set.

Whilst on its side the DGL1010GM’s automatic grade match facility can be used for automatically aligning of the vertical beam by using the receiver on its side.  Again the laser will automatically hunt for the receivers and lock onto it. This features makes this laser level handy for fence alignment applications as well as other construction jobs.

The DGL1010GM can also be used inside for visible installation  work to produce both vertical and horizontal laser lines.  The beam is intensified with the scan line mode. Which means instead of the laser rotating a full 360 degrees it draws a line left and right.  The size and position of this line can be adjusted using the remote control.

Li-ion Power

The laser level itself is powered by a substantial Li-ion battery pack that can be charge either whilst inserted into the laser or externally.  The DGL1010GM also comes with a standard “D” cell battery holder so you can carry on with your work when someone forgets to charge the battery.  The smart remote control unit and millimeter receiver use “AA” Alkaline batteries.


The build quality for this laser is impressive with full cast metal internal chassis and heavy rubbersied outer housing.

DGL1010GM Quality Built

The DGL1010GM comes with a certificate of calibration and an automatic 5 year warranty with no registration required.  So you sure the laser level is ready to get straight to work.  In conclusion the RedBack DGL1010GM is a professional laser levelling and grading system  packed with features you will be pressed to find on other lasers levels twice its cost.

What makes RedBack Lasers Different to the Crowd?

EGL624 Concreting

Many rotating lasers on the market these days look very similar to each other, with a broadly square shaped casing, handle on one side and a four glassed light house on top.  Many on the market are, indeed, pretty much the same under the skin but RedBack rotating lasers are very much different and in the following post I will detail the differences and what makes RedBack Lasers a better option.


RedBack Lasers – Safety Cage Technology

imex, powerline, cpi, pls, tuf, ebay

On the RedBack Below note the Steel Chassis top and bottom with steel posts, also note heavy duty cast metal pendulum assembly inside the chassis and thick rubberised plastic lower casing.  The difference in construction is clear. 


RedBack Electronic Rotating Lasers are constructed very differently to most in that they have a full steel or cast metal chassis protecting the internal mechanics and electronics, this we call Safety Cage Technology.  This means that RedBack electronic rotating lasers are much tougher than those without this technology. Most brands have all their mechanical/electrical components built directly onto the outer casing which is fine until the inevitable drop or knock happens.  Without any chassis around these parts gears can get dislodged, sensors damaged, the components can even break completely away.  With RedBack’s Safety Cage Technology, all these parts are all safely cocooned within it.  Its true that the outer casing may get damage in a heavy fall, but its just the skin, the laser level itself is often ready to go back to work.


RedBack Lasers 3 Power Options

RedBack Lasers 3 Power OPtions

All RedBack rotating lasers have three power options; Rechargeable batteries as standard (except the 509KIT where it is an option) some models with Ni-Mh and others with Li-ion technology. Mains power adapter/charger allows running of the mains power for indoor operations. Standard Battery power either “AA”, “C” or “D” cell.  This is all standard and included in the advertised price.  Many brands advertise a price without rechargeable batteries and charger and sell them at a premium price later.


RedBack Lasers Automatic 5 Year Warranty

RedBack Lasers 5 Year Warranty

All RedBack Electronic Rotating lasers have a standard 5 Year warranty and its a genuine 5 year warranty in that its automatic, NO registration is required and so NO penalty of a reduced warranty if not registered.  So when you see other brands offering a 3 or 5 year warranty make sure it really is.  They know that 80 to 90 percent of people forget to register and so under their terms purchasers now only get a 1 or 2 year warranty instead.

RedBack Lasers Calibrated and Certified

All RedBack Lasers, rotating, line or dot have been checked and calibrated here in Australia by one of our technicians on our CCTV calibration station and certified with the date of this calibration.  This ensures a couple of things; firstly that the laser level is operational before leaving our warehouse and secondly that it is operating within specified tolerances. The included certificate includes the name of the technician and the date the calibration was carried out.

So in conclusion not all rotating laser levels are created equal, RedBack Lasers may cost a little more than some available, but its because RedBack Lasers are better constructed and use better components to many and are checked and calibrated in Australia.  This is also why RedBack Laser warranty for electronic rotating lasers is automatically 5 years because they are built tough for reliability on the work site.

How to use a Basic Rotating Laser


As Prices fall on quality rotating lasers, more and more builders and DIY self-builders are buying them so here is a very basic guide on how to use a basic rotating laser.

Most lasers on the market today are automatic levelling so for the purpose of this guide we will assume you are using one of these, secondly I’ll assume you are using the laser to level outdoors.

First thing to do is to find a good spot to put the tripod and laser, somewhere that is out of the way so it won’t get knocked or damaged is a good start but also, most importantly, a position that allows a clear view of the site that you want to level. Laser beams are beams of light and like any other light will stop if blocked by an object, when levelling you use an electronic receiver to “see” this light so if there is something between the laser on the tripod and the receiver then the receiver won’t be able to pick up the laser and so not be able to show you level.

There are two main types of automatically levelling lasers; the first uses a pendulum and gravity to find level and the second used electronic sensors and motors. Gravity pendulum rotating laser almost always have a pendulum locking knob which is engaged when you are not using the laser to protect the mechanism, so to use this type first thing you need to do is locate this locking knob and unlock the device. Unlocking the pendulum allows the pendulum to swing free within gravity and after a few seconds due to a dampening mechanism will settle into a level position then all you have to do is press the power button and the laser beam prism will start to spin creating the rotating laser dot. With electronic leveling mechanisms simply power up and the motors and sensors get the laser into a level position and the laser beam will rotate.

The rotating beam is drawing an invisible (to the naked eye) flat level disc with the laser level being in the center. Next turn on your electronic receiver, the receiver will most times have both a visual display and audible sounds. Hold the receiver facing the laser level and move it up and down slowly through where you think this invisible laser disc is when the receiver passes through the path of the rotating laser it will indicate this and the display and sounds will indicate when you are slightly above the laser, slightly below the laser and exactly on it. This level point indicates a level height between the receiver and the laser level, Now by attaching the receiver to a staff or stick you can move around the site taking readings and determine level at different parts and so level the site with the help of hurdles, stakes or other means.
