The LDM85 is a pro-grade tool, measuring as far as 85', and is IP54 rated for use in dusty and rainy environments. It also features a backlit display, making it easy to read. This laser distance meter can measure length, area, volume and continuous measurements.

Worth much mate than what I payed. Must buy for trades..300 high bay lights set at 12’ between purlins. Lost my magnet part of fat max tape and bought this instead of replacing. I’ve tested couple times and always within 1/8” of tape. For 30$ Can’t go wrong. When your trying to extend tapes at 15’ and it’s bend throws you off 2-3” I’m so glad I tried this!!

75' is about the limit and that is at dusk. 50' is more realistic and that's not in bright sunlight 😔

Laser measure was off 5 6 inches constantly from 35 feet in air laser dot was as big as a half dollar. Screwed up a duct line 5 inches higher than what it should be. 148" x 42" duct on cable not easy to adjust once set!! Waste of time and money

This is low priced, good enough quality and takes accurate measurements. Unfortunately, it does not operate reliably when used with rechargeable batteries. A fully charged battery displays as mostly depleted and the device shuts off long before the rechargeable batteries are anywhere near dead. Very disappointing; one of the major reasons I selected this product is because it uses AA cells and I am making an effort to use only AA cells in my household so they can all be rechargeables.

Overall a good product. Getting feedback occasionally slow on laser. Compact and relatively easy to use. We are in constructions and it is an indispensable item.

I purchased the Johnson Level 130' laser measure from Amazon's deal site for a song on a lark. I expected it to be larger: in fact, the tool is about 2/3 the height of a can of soda and half as thick. Although it has a lanyard hole it includes no wrist strap. Measurements work via the reflection of a laser off your target captured by a sensor behind a camera shutter (you can actually hear the shutter go off like a DSLR when you take a measurement, and the length of time the shutter stays open gives you an idea of whether it's struggling in bright sunlight or with an overly-reflective or translucent surface).I've found the measurements to be accurate and repeatable. In fact, accurate to 2/16" over 130' is probably better than you could do with a tape measure. You can also skip the calculator for common tasks like adding or subtracting subsequent measurements, taking into account the length of the tool, and measuring the area of a square, volume of a cube, or distance between two points via Pythagorean theorem. I mapped the square footage of every room in my house in about 5 minutes, a task that would have required an assistant and 30 minutes with a tape measure.A very cool feature they failed to mention adequately on the box is that you can set the tool to semi-continuous measurement, during which it will beep distinct tones as it records points further away from or closer to the unit until you pause it. This lets you, for instance, take repeated measures to make sure your couch is going to fit through the smallest clearance in your staircase, or find the distance to the deepest recess of a wall corner from a point, by saving the longest and shortest distances in the sequence.My complaints are few and far between, but they must be aired. The excellent display backlighting is let down by no backlighting behind the keys. The addition and subtraction functions are non-obvious (why do I have to press "+" or "-" both before and after taking the measurement I want to add or subtract?). The keys are mushy and unresponsive, which makes taking measurements less accurate because you're jiggling the instrument around trying to get it to register the button press. Finally, why can't I tell the Pythagorean function that I'd like to measure "a" and "b" rather than "c" and "a"? Oh well, guess I'll have to take care of that bit on my calculator.It would also be great if the unit included built-in bubble levels to make sure you're measuring plum and level, but now I'm just nitpicking.

When it comes to accuracy, lasers will beat out sonar every time, and in just about every condition. It is said to be slightly sensitive to operation outdoors in bright daylight, but that seems like a fair trade-off, considering that sonar units will be thrown off by furniture and other things in a room. You can set this thing on a table and fire it at a distant object ten times in a row, and it will always come back with the same result.The device can measure from one of three reference points: the back (or bottom, if you stand it up), the front (where the laser optics are), and from the end of a "corner extension," which is a little piece of plastic that flips out on a hinge and could be useful for measuring from the inside of a groove or some other place where it would be too wide to fit. This is because you need to point the beam straight at the object you're measuring - the beam should hit what you're measuring at as close to a 90 degree angle as possible.If you're measuring the distance between two walls, you'd tell it to measure from the back of itself, and then hold the unit to one of the walls so that its back was flat up against the wall. Same for measuring ceiling height.If you have to do a measurement where there's something blocking the laser from reaching the far object - for example, a protruding door frame - you tell the laser to measure from its front, and then line up its front with the object you're firing from.The unit can also measure the area of a rectangle, or the volume of a cube. It will tell you which wall (or floor) to fire the beam from in sequence to get the measurement. This is fairly easy.The only thing I don't like is the Pythagorean (indirect) distance measurement. Fire the laser at two points, and it will use the Pythagorean theorem (a^2 + b^2 = c^2) to figure out the length between the two points. If you fire it at the point closer to you first and the point further from you second, it will give you an error. However, if you measure the exact same two points further first and closer second, it will give you the answer. Unless I am mistaken, there is no use for this other than to determine the length between two points. Therefore, from a usability perspective, it should just detect this case and flip the measurements internally. If I was that particular about the math, I'd probably just measure the two distances and do the calculations myself - but the whole point of this is to save time.

Very simple to use. The best feature is the backlit screen. It can be seen clearly in all circumstances. Seems to be very accurate.
