Huepar Box-1G Laser Level Self-Leveling, 150ft Outdoor Green Cross Line with Pulse Mode, 150° Vertical Lines, Magnetic Base & Battery Included – High Precision for DIY and Professional Use

I purchased this almost 2 years ago. This spring, when I tried to use it, it would not turn on. I contacted the manufacturer, and they quickly agreed to send out a replacement.

I used the horizontal plane of this laser level to determine where to add soil to adjust a yard area to a uniform very slight slope. I used a makeshift stadia rod made from a tape measure clipped to a scrap aluminum extrusion. Even in bright sun, I could see the green line on the stadia rod up to 25 feet from the laser by casting a shadow on the rod with my hand or the clipboard I was plotting elevations on. As another reviewer said, it helped to know roughly where the line would be, and by 25 feet from the laser it was very faint, but still just visible enough to read once I found it. Later in the day, as the sunlight faded, the laser was bright enough to see easily over much longer distances.Unlike another reviewer, I received my level in the "locked" position, as it should be, so I was not too worried about its calibration. Just to be sure, I tested its calibration immediately indoors and found its error too small to detect at all (that is, within the 2-3 mm width of the laser line) at 40 feet, which I figured was plenty good enough for leveling dirt... so good that I probably got lucky with this particular unit.Here is how I tested: Set the level up on a tripod next to one indoor wall. Mark the horizontal line on the near wall; turn the level and mark the opposite wall. Move the tripod to next to the opposite wall and adjust the height until the line matches the level marked there. Then rotate the level and compare the laser line on the first wall to the original mark on it. The difference is the total error over the round-trip distance from the first setup point, to the second, and back. So if you see a 1/8" difference with the two tripod setups 20 feet apart, the error is actually about 1/8" in 40 feet. I could not detect enough error to measure it.)I used four old 1900 mAh rechargeable AA batteries, turning the laser on only periodically when needed for measuring or for short periods of work with frequent checking. After two days of work and two nights of leaving the batteries in the unit overnight (turned off, of course), the batteries are roughly half discharged. If I had to leave the laser on continuously for a job, I would bring a second set of batteries and charge them while I used the first, just to be sure. But if you use the laser to lay out pencil marks or take elevations periodically, turning it off at other times, then battery use does not seem to be a problem.This level comes with a small stand-up scale for leveling floors or other surfaces that you set the level on directly. This is a essentially a very short, self-supported stadia rod with a zero mark at the height of the horizontal laser above the unit's feet. The level also comes with a magnetic bracket so you can easily mount the laser to ferrous surfaces. I found the magnets more than sufficient to securely support the laser on the door or sides of my refrigerator. The included soft, slightly padded case holds the laser and both accessories with moderate protection. You could even jam in an extra set of batteries. As some other reviewers note, the manual is very brief, but this tool is pretty simple and does not require anything more. The manual does not explain the floor-leveling scale or the magnetic bracket, but if you can't figure them out, you probably don't need them.One can pay a lot more for this kind of tool, but unless you really need longer range in bright sunlight or want to be able to calibrate it yourself, this one will do the same job.

This laser level did the job I needed it for and will certainly come in handy for future needs. The user interface is a little confusing at first (it could probably use a few more buttons) but if you follow the directions it does work as designed and it makes sense that you have to take it out of self-leveling mode to shut it off to protect the self leveling mechanism. The horizontal beam has about 120 degrees of viewing angle but it is brightest at the center of the beam so for outdoor use in bright sunlight, I had to place the level on a flat surface and turn it to aim it at each target (stakes in the yard). Having a dark target makes it easier to see in full daylight but I was able to see the beam about 30 feet away with no problems. To reach the full 150 foot range you'd probably need to use it in the evening or indoors.

This laser level is excellent for grading and leveling. Even in bright sunlight, the green line was visible up to 25 feet with some shadowing. Calibration was flawless, with no detectable error over a 40-foot test.With the compact design it uses 1900 mAh rechargeable AA batteries. That lasted two days with intermittent use. Included accessories like the self-supporting scale, magnetic bracket, and padded case add practicality. While the manual is brief, the tool is intuitive. Unless you need long-range sunlight visibility or self-calibration, this level is a high-performing, cost-effective choice.

I ordered this as a product to help me when backing up to my 5th wheel travel trailer. It is a non-typical use for the product but I wanted something that would produce a green laser line that I could use to line up my truck over the gooseneck ball and hit the center of the trailer. I place the level on the bed rail and shoot the laser over the gooseneck ball. It is just bright enough I can see it as I am reversing up to the ball. It allows me to be lined up on the center of the trailer and that, in conjunction with my camera I can nail the placement each time. I am sure I will find use for it around the house as well, but for my non typical use case it works fantastically.

Good product, great customer service

Works perfectly if you just want it for indoor use. Outdoors, in the daylight, the laser is not visible around 15 ft and further. However, I purchased the additional Huepar laser detector and using the pulse mode on the laser module, was able to detect the laser 50 ft away. Didn't test it any further than that yet, but suspect it would work as described.

Compared to my friends Bosch professional gll 100 g, just as bright if not brighter but slightly less crisp or thin laser. Auto leveling works great even years later and I haven’t treated it nicely.
