3. Johnson Level
- Brand: Johnson
- Manufacturer: Johnson
The Johnson Level & Tool 40-6517 is a budget-friendly rotary laser system designed for smaller projects and occasional use. It features self-leveling in the horizontal plane and manual leveling in the vertical plane, making it versatile for basic leveling and alignment tasks. The system includes a wide range of accessories, such as an elevating tripod, grade rod, detector, tinted glasses, and a hard-shell carrying case, providing excellent value for its price.
While testing, the 40-6517 performed adequately for light-duty tasks, such as setting foundations, aligning walls, and leveling deck floors. However, its accuracy and range (200-600 RPM rotational speeds) were less impressive compared to higher-end models. The audible and visual alarms are helpful for ensuring proper leveling, but the manual vertical leveling can be cumbersome for inexperienced users. This model is ideal for DIYers and small-scale contractors on a tight budget.
Pros
- Affordable price point
- Comprehensive accessory kit
- Self-leveling in horizontal mode
- Visual and audible alarms for safety

With an IP66 rating, it is built to withstand harsh conditions, including dust and rain. It features a 400-meter range and comes with accessories like the LS-80 sensor, sensor holder, and carrying case. While slightly less powerful than the RL-H5A, it retains the same robust build quality and ease of use.
In our testing, the RL-H5B provided consistent accuracy and smooth operation for medium-sized job sites. Its self-leveling feature simplifies setup, and the included field book is a thoughtful addition for logging measurements. However, the shorter range compared to the RL-H5A may limit its use for larger projects. This model is a great choice for contractors seeking a balance between performance and affordability.
Pros
