          A true Professional-Level Tool
          The Bosch 800 ft. Self Leveling Rotary Laser Kit is really a professional-level product. While DIY'ers will find it useful, its construction, completeness and multiple accessories that are included make this perfect for a professional contractor to use in the field for setting up grade slopes for driveways, establishing plumb lines in construction, or setting up horizontal and square lines for cabinet installation. This kit does it all, but does require a certain learning curve to fully realize all the features. I had shelving that needed to be mounted in my garage and this was a perfect tool to establish a horizontal, level line across the wall. The kit comes with a multi-functional tri-pod that allows each of the three legs to be set at a different length so that the tool can be mounted on a level plane regardless of the terrain. The laser device will self-level as long as it is within 5 degrees of level. The included receiver is a must have if being used outside in sunlight as the red laser doesn't show up very well unless you're using the included red lens glasses or the receiver, which emits a loud beep when the laser is hitting the appropriate place on the receiver. The kit comes with sturdy carrying case to protect the laser, as well as batteries for the laser and receiver. Overall, a good value and professional-level tool.

          Awesome laser for leveling.
          As a former construction project manager, I can say that this laser is far better than the ones we had back when I was using these every day. I like that this kit comes with a laser that will go up to 800 feet. That said, the rotary distance is much less (maybe 200-300 feet). That should be plenty for anyone except the largest jobsites. The laser is able to be put in rotary and several sweep modes which allows for a much longer range. Also, it can be put on it's side and used in a vertical mode AND it will self level in any mode. The kit comes with a hard case including a tripod or a wall mount, reflector and receiver as well as measuring stick. Overall, I'm super happy with this and look forward to using it to level out my yard this summer.

          Precision rotary indoor/outdoor self-leveling laser
          Bosch GRL800-20hv self-leveling rotary laser comes with the rotating laser, red laser glasses, batteries, red target card, 8 ft. grade rod, BT152 aluminum tripod, WM 24 wall mount and carrying case. This rotary laser is made for indoor and outdoor use. Its IP56 rated for protection against dust and water. This laser has up to a 800 foot working range so it can handle larger job site applications. I really like the self-leveling feature of this tool. It simplifies using it and is a timesaver. The laser receiver has a bubble level built in to better manage measurements when using the 8 ft. grade rod. The included tripod is well made and is easy to adjust height. There is a hook in the center to add additional weight if needed, which could come in handy on a windy day. The rotating laser has 3 speeds and a switchable shock-warning function, should the laser have a position change or shock to the tool. To make the most of this handy laser, reading thru the manual will give you insights on all its abilities and will give a better result of your project. Highly recommended.

          Very Easy to Use and Ideal for Outdoor Construction Requiring Ground Leveling
          I’ve always wanted a Rotary Laser Level and decided to obtain the Bosch GRL 800 20 HVK Kit. It comes with the Self-Leveling Rotary Laser Level, Laser Receiver with Bracket, Aluminum Tripod, 8 ft. Aluminum Grade Rod, Wall Mounting Bracket, Laser Glasses & Target Card, and a sturdy Carrying Case. This is a professional grade laser leveling tool and is primarily used outdoors for leveling foundations and ground, installing drainage pipes, leveling and squaring decks, etc. It’s can also be used inside, but there are better line laser options for use indoors. The instructions are very well written with lots of safety precautions and graphic instructions on proper use to the tools. It has an accuracy of 3/16 inch at 100 ft. and can be used up to 800 ft. range. I especially like the ability to select multiple angles the laser is transmitted, which restricts the target area of the laser. Reducing the rotational speed also makes it much easier to see the laser beam indoors. I used it to check the level of a recently constructed deck. I sure wish I had obtained this Bosch Rotary Laser Level before building the deck. My only complaint is the Grade Rod uses fraction of inches, which is difficult to use. I will be purchasing another grade rod that uses 10th of inches, which is easier to calculate the difference of elevation. Other that Grade Rod, I am very happy with this Bosch Rotary Laser Level Kit, and recommend it for anyone that needs a professional grade leveling tool outdoors.

          The Bosch 800ft. rotary laser level complete kit self leveling with hard carrying case is all I ever wanted in a a rotary laser kit. I have 2 small 40ft. lasers that I have used for years for remodeling jobs and a transit level for larger outdoor projects. This Bosch rotary laser level kit will save me a lot of time setting up footers. My new Bosch rotary laser level is accurate up to plus or minus 3/16in. at 100ft. and a range of up to 800ft. with laser receiver. I love the quality of Bosch tools and I can not wait to use this rotary laser level.

          This kit has everything you will need for using the laser lever in any situation. The tripod is quick to set up and the laser self calibrates before I am ready to start marking lines. I especially like the wall mount, two screws in the wall and you can mount it in a small room and not have to worry about tripping over the tripod. The coolest bit is the reader that you attach to the leveling rod, even though you can't see the laser when you are at the other end of the driveway it will see the light and you can take readings. I often work alone and this feature saves me time and money when I really only need a helper for a few little tasks.

          Everything you need in one place and coverage up to 72 acres! Construction layout or landscaping I'm finding a lot of ways this level makes it easier for one person to measure and mark projects. Although not a crossbeam laser it does have horizontal and vertical setup that let me locate inside and outside to install an outlet through 11 inches of concrete and get it in the right place. Sure, it is possible with levels and lines but it is easier with laser. It has a plumb bob hook on the bottom for exact location of your reference point as well as a plumb laser out the top to mark ceiling location precisely. The receiver design allows use from front or back, measures up to 13 feet height, and has a bubble level visible from top or bottom so you are measuring plumb. The auto-leveling takes little time and you can switch to manual and set either or both the X and Y plane angles which lets you measure height from the desired slope rather than level height and calculating desired height at each measurement. The manual angle is not displayed so you do have to set an initial reference before adjusting the manual slope. Using slope can eliminate setting up (and knocking over) a lot of grade stakes while moving dirt for drainage or water runoff management through general sloping or specific decorative water feature construction. The size of project and equipment used will guide a lot of the approach you may prefer in each case. There is also a ceiling mount and ceiling target to help keep suspended or other ceiling work level because nobody likes to see a wavy ceiling job. The included glasses enhance visibility of the laser but are not laser safety glasses. Never look directly at a laser as serious and permanent eye damage can occur.

          This is an awesome tool with a steep learning curve if you have never used one before, but trust me, this is WORTH EVERY PENNY YOU SPEND AND MINUTE YOU TAKE LEARNING IT. I have a number of projects going now that I have free time, the two biggest ones are setting a retaining wall/planter wall and regrading my side yard. Since I also have some building and reno projects planned, I picked this up so I could work on them myself. The REVOLVE2000 is a lot of tool: it allows you to do dual slopes, as well as setting horizontal and vertical level and plumb lines. Setting grades is easy too. This kit is really all in one: laser, tripod, remote receiver, grade stick, batteries, carrying case…all you need. The self leveling is really, really nice: as long as the tripod mount is kind of level you are set. I used it right out of the box to set shelves on two walls so they were level and even with each other. The remote receiver means that setting grades is a one man job and I don’t need help to do it. My friend, who is a contractor/builder, also thought this was one incredible tool. The laser can be a little hard to see in sunlight but the target card, remote receiver, as well as the red glasses provided help a lot here. Only drawback (for someone like me) is that it takes some time to learn all it can do; thankfully, there are lots of videos on how to use HV Rotary Lasers on the internet; I’m looking forward to Bosch putting one of their own training videos together. Recommended for contractors and those in the building trades, but very handy for a DIYer like myself doing big projects.

          Easy enough for the DIY’er to figure out (most of it) and sophisticated enough for the everyday professional on a budget. The Bosch Resolve2000 Self-Leveling Horizontal Rotary laser kit is a wonderful tool that comes with multiple accessories that is all packed up into one single carrying case. The main unit of the kit is the GRL2000-40HK rotary laser which features a “red” beam horizontal self-leveling laser along with a vertical beam simultaneously emitting from the top. The unit takes std. D cell batteries, which is nice. The front panel is well laid out and mostly self-explanatory. This is not an LCD display panel, only function buttons which after turning the unit on you really want to use the remote. There are two large rubberized carry handles to protect the front display and a cage to protect the rotating laser head. The cage is marked with X & Y +/- directions used with the slope function. The kit comes with a remote with two AA batteries. I found out quickly to make all the adjustment with this remote because if you disturb the laser unit by pushing on a function button the shock-warning “disturbance” function kicks in the stops the laser making you start all over again. The remote can do all the functions as found on the front panel except for turning the unit on or off, it however can put it on standby which is not on the unit front. The declared accuracy for the unit is +/-1/16 of an inch and I tested it at 30 feet per the calibration instructions and found it to be right on. The laser is rated to 2,000 feet when using the receiver but the furthest I could do was 200 feet, in moderate daylight, and it worked perfectly. The unit can be placed on its side (HV model only) and used as a vertical rotary laser instead of a horizontal. The kit comes with nice adjustable aluminum tripod with shoulder carrying strap that includes a wraparound leg lock strap. The tripod can be collapsed to 30 inches and extended to 64 inches (not deployed just the length) and has foot pegs to help push the leg tips into harder dirt. The lowest stable deployed height (legs spread all the way out) I could get was 17 inches to the laser and the highest stable deployed height (legs almost collapsed) was 70 inches. The connecting thread between the unit and tripod is 5/8-11 with the tripod having the male thd. The kit also come with what Bosch calls a wall mount/alignment unit or bracket. Once you attached the unit to the bracket you can then mount on or suspended the unit from the ceiling or whatever framework. This configuration is mostly used with the supplied red mirrored target. Red glasses are also supplied in the kit and I was kind-a surprised on how much better you can see the red beam with them. The leveling rod or grade stick is made from aluminum, marked in ¼” increment’s, 30 inches’ when collapsed and 13 feet when fully extended. The LR20 laser receiver can be used with or without the grade stick. If the grade stick bracket is removed the imbedded magnets can be used instead and will support the receiver’s weight in both horizontal and vertical positions. The receiver has a horizontal bubble level, the bracket attaching it to the grade stick has a bull’s eye vertical level. The receiver has a display on both the front and rear of the unit, which is really nice, so you do not get you head in the way of the beam like I tend to do (bifocals). The receiver does have a back light that can be turned on for dusk or night operation. The receiver has a two-volume level audible alarm that guides you. A fast beep means your too high and slow beep means your too low. A solid tone means you right at level. The receiver has visual indicators also that tells you which way the receiver needs to move to get to level. These show on both front and back displays. There are three different accuracy settings, fine medium and course, that can be toggled through using one selector button on the receiver. The fine selection will display 1/32 and 1/16” increments, the medium will display 1/8 and ¼” with the course displaying ½ and 1”. Let’s talk about the beam itself. This is a red laser beam that can be moved from rotary to stationary to oscillate depending upon your needs. The rotary option has three different speeds with the vertical beam always on. The rotary beam can be changed from clockwise to counterclockwise rotation and then switched to oscillate mode. Single point can be achieved when running through the rotational speeds with the last speed being stop. There are three different sweeps when switched to oscillating, which IMO are 5, 15 and 30 degrees of arc. I could be wrong but that’s what my math works it out to be. These are all toggled through using the same function button on the unit or remote. Just like the rotary option, this can be changed from going right to left to going left to right. The single slope or duel slope option is somewhat confusing but if you play with the unit long enough you finally get the hang of it. The top of the laser unit has directional arrows showing both + and – in X and Y. You can tilt one axis at a time up to 8 degrees in either direction. To go back to auto level just push the center button and your back. Things I liked, uses common batteries, easy to identify function buttons and everything you need is in the kit. Things I did not like, mediocre to poor directions. If you have used a rotary level before the directions could be adequate but not for a newbie. Bosch web site has no instructional videos for using the different functions. People learn in different ways; I need some “how to” videos along with the directions to shorten the learning curve. There is no display to show you how much of a slope or angle you are at like other rotary levels have. The function button on the unit or remote has no defined amount of movement per push. I found that you need to hold the button down to get the head to angle the beam, there seems to be no rhyme or reason on how much it moves every time you push the button. All electronics, brkt’s and targets are made in Malaysia, tripod and grade stick India and the carry case in the USA. This is a great unit that will do everything a homeowner would ever want to do and then some. The accuracy, configuration versatility and working distance puts this unit into the professionals use area. Good price point, recommended.
