Bosch GRL4000-80CHVK 18V REVOLVE4000 Connected Self-Leveling Horizontal/Vertical Rotary Laser Kit

I used this tool first for leveling the grade for a new paved parking lot beside my house. When working outside in the sun, you need to use the target but when it's attached to the sight rod it's quick and simple.

Absolutely amazing. You can control it with your phone and also do slope measurements. You can calibrate it if it falls over and its water resistant. If it rains you don't have to worry about it.

I've been using this self-leveling rotary laser for a few weeks now and I like it more day by day. Even the other crew members really enjoy using this laser. Very user friendly and great visibility on bright days, like here in the desert. Bosch picked the IP68 wisely, you can bring it with you to any jobsite and condition. It's rugged and durable, not to mention very accurate...that the quality Bosch is known for. Bluetooth and remote is great feature to have. Love the feature it can be operated by any Bosch 18V battery or 4 D batteries. In the past it happened a lot that we ran out of juice, D batteries empty and no spare on hand in the middle of nowhere. With the 18V battery option you get a very long run time....I have not timed it yet, but easy +20 hours.

Overall it's an amazing rotary laser for small and big jobs, occasional laser work or professionals. Carrying case is quite large, but stores all accessories.

This is such a great leveling tool! It comes with everything you'll need to make sure your project is 100% level. It's accurate in the sun, clouds and easy to use. The Bluetooth connectivity is just the cherry on top to advanced tools!

This kit by far exceeded my expectations!! I am blown away with the accuracy, ease of use and overall durability of this tool. Grade work is a breeze with this tool! I could not be Happier with this product and I know it will come in handy for years to come!

Whether you're a contractor, builder or just a DIYer with a large project, the Bosch REVOLVE4000 Self-Leveling Rotary Laser is the ultimate tool to ensure that your project is perfectly level every step of the way.

The kit that I'm using comes complete with all of the bells and whistles. This includes extra items like a tripod, wall mount, remote control and a case to carry everything in.

Right out of the box, you can tell that the unit is durable and well built. The self-leveling laser is encased in a protective housing, and the rest of the body sports a clean, yet rugged, design and finish. Coupled with IP68 dust and water protection, the REVOLVE4000 is about as durable as they come. So far, it's held up extremely well, and there's not much I worry about while using it in the field.

In terms of functionality, the REVOLVE4000 is an absolute performer! Upon first use, I found that the level is extremely user friendly. It's a breeze to set-up, and I had it running in no time at all. The laser can be oriented horizontally or vertically, and it's highly visible - even when outdoors. Most importantly, it's very accurate! As the name suggests, this level can operate withing a 4,000' range. I haven't had a project quite large enough to push the limits on the distance; however, it has operated amazingly well on a variety of different size jobs and scenarios.

Extra perks like the remote control and Bluetooth capabilities add an array of connected user functions. This is extremely useful, especially when on a busy job!

Overall, I really like the REVOLVE4000! Both user friendly and highly capable in just about any scenario, this level has quickly become one of my favorite go-to tools on the job site.

Talk about state of the art! Bosch 18V Self-Leveling Rotary Laser Kit absolutely exceeded my expectations. This Kit has it all to allow for the project you are working on to be simpler. The laser light itself is extraordinary bright even during bright summer days here in AZ at over 100 degrees. Extremely well equipped Kit. Everything from the rechargeable li ion battery ( with charger, alkaline batteries for backup, the device itself, an adjustable heavy duty stand, a wall mount etc neatly organized in a heavy duty hard shell weather proof case. This Kit could not have come at a better time as I was starting a concrete patio project at my house. Multiple levels, I needed accurate measurements. With further research and reading the easy to read, easy to follow instructions it allowed me to level the ground so much easier and accurately! The leveler made locating the high and low areas of the ground evident. The hardest part of using this Kit is that you have to input your jobs/projects and then the leveler does the rest. ( Besides the work!!) I Highly recommend this Kit can't say enough good things about it. It is definitely reliable

I got this because our foundation was slipping due to run off from the hills around our house we have it ditched completely but still have some run off from the hills down into our yard so we needed to add new center blocks and straighten everything up before everything gave out and this was a life saver it was super easy to set up and came with easy to read instructions and the beams are super bright even in the day the alinement was spot on everything booted up great and has worked great since we got it. The set is a little heavy but comes with its own case that is bulky. Another great thing I liked about the unit is you can use a app with it and everything within the app was easy very simple set up using Bluetooth would definitely recommend rather you have a small job or a large one

This kit is a beast! It is incredibly accurate and easy to use once setup. It works in bright sunlight which I was worried about. The alkaline battery adapter comes in handy more than I thought it would. The Bluetooth connectivity worked very well and came in handy. The only slight issue it the portability, it is large and took up a lot of space in the truck. Otherwise the features and functionality works as advertised and exceeded expectation.

I use the GR L4 1000 to install reinforced concrete pipe at O'hare International Airport. So far so good. It's accurate up to at least 1400'. The unit itself as well as the carrying case are fairly large. I plan on using it to install foundations and grading work also. The 4000 foot range is probably overkill for most applications, but will come in handy when needed. I haven't used the remote beyond 30' so I don't know it's full range as of yet. The batteries last about a week with moderate use before needing to be charged. I would definitely recommend this unit to fellow contractors in the same line of work. Overall I am very satisfied with the unit.
