Accurate enough for me

I have learned the hard way that many measuring devices are not accurate enough to be useful for anything. My experience with levels has been no exception. My old laser torpedo level ceased operation and I needed a replacement. I chose the 40-6184 based on the fewer negative reviews and personal experience with my Johnson 24” beam level, which is accurate enough for my use. I purchased the level knowing there was a high probability I would return it. I was pleasantly surprised to find the horizontal accuracy acceptable. It is a 10” level and I had to place a .003” shim under one end to get the most accurate reading I could visually discern (flipping end to end). Projected to 10 ft that is about 1/32” error. Not perfect, but this is not a machine tool grade level. I am sure I introduce as much or more error in reading the level in a typical application. For the record, my 24” Johnson level needed .005” shimming. At 10 ft, that’s a bit under 1/32” error. The vertical level was off more than acceptable, but Johnson provides a calibration feature for it. I dialed it in to where I need it. Finally, I checked the y-axis laser accuracy relative to level. While the dot is larger than I would like to have, you just work to the center of it. I have an 8 ft surface flat to +/- .003”. The laser dot was spot on level over the 8 ft. I don’t have a reliable way to check the vertical and x-axis beam accuracy to the same confidence as the y-axis horizontal.I can’t speak to the durability and I agree with a previous review on the robustness of the laser switch. Its design quality does not match the overall craftsmanship of the level.Other than being heavy, I have no other complaints and recommend this level. Just check it for accuracy when you get it. There may be variation from batch to batch.If you don’t really need a laser, there are higher quality torpedo level options available in the same price range, but this was the best I could find in a laser torpedo level and I would have been willing to pay twice as much to get a better one.I give it 5 stars based on its performance relative to reasonable expectations for a laser level at this price point.

Love the hold power of the magnets

Heavy n well made the lasers help with layout

Works great.

1st one was faulty, they expedited a replacement. Works quite well (except) the dot is pretty big. Some workers liked that, I prefer a more precise beam. Also, the base takes some getting used to.

Great laser!

Perfect for layout. Exactly what I needed.

Perfect little tool.

This is the second one that we have ordered. The first one had a battery stuck in it. We couldn't get out to change other than that. This thing is great.

P**.

One of the best tools in my toolbox

The magnet on this thing is serious! The lasers make squaring pipe an easy one man job. The vails I have found unreliable tho. I’ve had 2 and neither have matched my Milwaukee or other Johnson levels that all match each other

Visible in daylight outdoors but expensive.

This laser is visible in daylight, outdoors. It is also visible for a further distance than most. I don’t know exactly how far it is visible but I have used it 75ft in bright daylight. Lowe’s did carry a different brand that would do the same thing for a fraction of the cost but they are no longer available so I was forced to pay the high price for this one when I left my Kobalt (from Lowe’s) on a job site. The Kobalt was under $20 and this Johnson is over $100. Not happy about the price but it is a good product.
