Johnson Level and Tool 40-6529 Review – Does It Get the Job Done?

Johnson Level and Tool 40-6529If you’re a carpenter, plumber or electrician, then you’ll love the Johnson Level Electronic Self-Leveling Horizontal & Vertical Rotary Laser Kit – 40-6529. It’s the right tool for both indoor and outdoor construction laser levelling jobs, providing versatility and accurate levelling every time for every job. With a vertical mount, the level has the capacity to self-level both horizontally and vertically and can be used for various indoor and outdoor applications which include but are not limited to levelling, checking cut and fill, setting foundations and footings, septic tanks and basement excavations, acoustical ceiling and drywall installation, aligning and plumbing walls, and contour framing. The Johnson 40-6529’s versatility also makes it the ideal tool for all kinds of trade jobs such as site work, carpentry, mechanical and electrical. This laser is also great for small jobs like hanging kitchen cabinets and lowered ceilings, landscaping and survey work outdoors. This model comes complete with a new electronically-controlled dual slope feature.


The base has a number scale which represent 360 degrees of a circle. Each leg has sectional extensions like a camera tripod. You can raise or lower the centre mast as needed using the hand crank and then lock it into the position needed. There aren’t many controls on this unit: one knob to turn it on and off and a compartment in the back for the battery unit. The pendulum mechanism remains locked in place when the unit is powered off in order to prevent damage during transport. For accuracy and guaranteed precision, the light begins to flash if the unit is more than six degrees from level. When the light is steady, it means that the unit has once again become level. The laser shoots out against the object in a T shape with steady, unlashing light. If it isn’t flashing, the measurement is accurate. If it is flashing, the unit is not level and needs to be adjusted. The user can be sure that T-shape lines are always 90 degrees to each other when the unit is stable and the light is not flashing.

What Some Buyers Had to Say About Their Purchase of the Johnson Level Electronic Self-Leveling Horizontal & Vertical Rotary Laser Kit – 40-6529:


“The threaded boss in the base of the laser unit let’s you thread it right on to the tripod and when it tightens up, you can still turn the laser unit on top of the base. That’s just another feature that can come in handy when you’re doing a lot of things in the same room” (


“The tripod that comes with the laser is very light weight but it’s more than strong enough for the laser head. The crank height adjuster makes it easy to set the laser where you need it. The tripod has a threaded adapter on it already, so all you do is screw the head piece on to it. If you struggle to get a level line around a room for hanging shelves or cabinets, this Johnson levelling rotary laser level could be just what you need” (thintz12, online review).


“I like the fact that I cannot screw this thing up” (hodr1000, online review).


Final Verdict

  • Push the power button and the laser electronically self-levels and calibrates itself.
  • Accuracy of 1/8 inch at 100 feet.
