I wanted a laser distance meter to do use trlateration and locate objects on my property and I didn't want to pay a surveyor. I have a 200' tape measure and it works fine, but is a lot of work to drag around and sometimes it is difficult to get the end to stay attached to an object. Also much of my property is hilly and wooded and I would rather not have to drag a measuring tape around. I wanted to give a laser unit a try and it needed to have excellent distance capability, at least 200'. This Huepar looked like it could get the job done.I got the Huepar because it has the longest range available, is rechargeable, and has an electronic level capability. It has all of the standard modes: distance, area, volume, cumulative area, and Pythagorean triangle measurements. You set the mode by pressing a button to cycle through the modes and an onscreen icon tells you what mode you are in. Also the icon has an indicator to tell you which measurements to make for the selected mode. Pretty simple to operate and you don't have to remember each sequence. The case seems very sturdy, a kind of rubberized plastic.I had serious doubts that the unit could actually measure out to 393' for two reasons. First the reflection of the laser spot would be pretty weak and this unit has the same class II laser as the others, and second holding the spot on target at that distance would be difficult. I tried measuring the distance to the back of my truck (silver color) and was able to get readings at about 104' in the daytime with overcast. Biggest problem was trying to keep the spot on the back of the truck while holding the unit freehand. I tried again at night and tried useing a brace to reduce the wobble and was able to get out to 250', but only if I could keep the spot on the license plate. I could tell when I hit the license plate because the spot became much brighter. It only took a few fractions of a second for the brighter spot to give me a reading. (Update) I bought a unipod to help steady the unit and was able to measure out to 340' at dusk. Biggest problem was keeping the laser spot on the license plate. I think any farther and a tripod is needed. A problem is that pressing the button to start the measurement knocks the laser spot off the target, but there is a secret helper for that. One neat feature is the "delayed measurement", where you can start a timer programmable from 5 to 60 seconds and then the measurement is made automatically. So using a tripod and getting the beam on target during the delay, should be a piece of cake to get a measurement.As far as I can tell, the electronic level angle is only for information. It is not used in any calculations.Conclusions: A good unit and knowing what I know now, I would still buy it for my purpose. However I will need to use some kind of prismatic targets that bounce the laser light back to the unit. I don't think a white target will do the trick, because for extreme range I think you need something that reflects directly back to the laser unit. I bought some 60cm x 60cm stickers, but it will be difficult to hit them at a distance. With a tripod to hold the unit steady, it might be possible to hit that small a target (yes it has a female screw hole on the bottom for a tripod). Alternatively I have some old license plates I will try using because they are a much larger target.Update. I glued Picatinny rails to the side, attached a 4x rifle scope (~$25) to the side, mounted it on a light duty tripod (~$40). I zeroed the scope so that the laser beam was parallel to the scope crosshairs. With the scope and tripod, I am able to hold the laser spot on a license plate at 400 feet. I made three measurements and got 404.17', 404.16', and 404.16' on a heavily overcast day with the license plate as the target. At that distance a good retro-reflective material is needed to get enough signal back to the laser receiver.Excellent repeatability, but I can't speak to the accuracy yet. But very pleased with the results.

This laser measure works perfectly and is very accurate, different measurements of the same place give the same distance. The level is great. The beam is bright. The device came with a case which protects it from damage. The tool will calculate the area of rooms, and it has many functions it can perform, the stored memory is a huge plus. Build quality is excellent and it seems very durable as it is rubber wrapped. It has a hole in the corner for a wrist loop which comes with it. Highly Recommended!!

I bought this on behalf of a friend who finds it difficult to shop on Amazon, and not for myself, however i had a chance to play with the device for a couple hours. I was very impressed by it. So much so, i'm contemplating buying one for myself. I had always viewed these devices as expensive toys, but this device changed my mind. I began to see the advantages over using a conventional tape measure, especially for one person trying to measure longer distances.This device has many advantages over its competition. The rechargeable lithium battery being one of the biggest. It's quite compact, light weight, and comes with a case and a small laser target. It also supports a variety of display modes: Meters, inches, feet & inches, and either decimal inches, or fractional. Much of the competition lacks this variety of display options. Once a measurement is taken, it's possible to switch between display modes, thus converting the readout to the desired mode (and back again). This works not just for the current measurement, but any stored measurement as well. However it must be noted that the screen's area for the fractional display is quite small, and will be difficult for many people to read the fractional digits (the rest of the digits are much larger, and easier to read).The manual only sparsely documents some of the more complex triangulation modes, and while i thought i understood how those measurements were to be made, based on flashing lines within the measurement mode icon on the screen, i nonetheless found some of the measurements difficult to make. I found the device beeping at me a fair amount, and based on the icon, could tell it had failed to take the measurement, even though the laser dot was quite visible, and would have worked just fine in a point-to-point measurement. The manual was absolutely no help in understanding the meaning of the beep and why it failed to take the measurement. While i was eventually able to get all the triangulation modes to work, some of the more complicated ones were very dodgy at best, for no apparent reason. The lack of well written, English documentation made it unclear whether the fault was with how i was operating the device, or in the device itself. Either way, that caused some of the triangulation modes to be essentially useless to me. Fortunately, those were modes i found to be esoteric, and likely wouldn't want to use anyhow. YMMV. While i was tempted to dock the device a star for this, i chose not to, because there is much about it which is, nonetheless, impressive (particularly in comparison to its competition). For example, its digital inclinometer far surpasses the bubble level on many competing devices. And its rechargeable lithium cell shouldn't be overlooked. Laser devices tend to chew through disposable alkaline cells, are costly, and environmentally unfriendly. The rechargeable lithium cell gives this device an insanely high number of measurements on a single charge (up to 8000, according to the specs). This gives one the ability to take measures with impunity, knowing you're unlikely to run out of electrons in the field.One unfortunate feature on this device, however, (and virtually all others) is its red laser. Don't expect to get the stated range of this device outdoors. If it's overcast, one might get half the stated range during daytime; even less if it's sunny. The included laser target might enhance the range, if you can manage to hit it (which will be challenging at a distance). Green lasers are vastly superior outdoors, or at greater distances. While green lasers have higher power requirements, the lithium cell has power to spare. I'd gladly trade number-of-measurements for improved capabilities that come with a green laser. Even if it meant i could only get, say, 2000 measurements per charge. A green laser would likely increase the range of this device significantly, make it much more usable outdoors, or in bright lighting conditions.That said, i did find a cheat. While a red laser can be difficult to spot in the distance, especially outdoors, a green laser is much easier to see. So take a green laser pointer (e.g. a 532nm 301 pointer), place it underneath or alongside this device, to use as a spotting laser. This kludge, while cumbersome, often (but not always) makes it possible to find (aim) this device's red dot. I suspect it would make hitting the reflecting laser target, included with this meter, easier to achieve. While the target is intended to make the red dot easier to see in unfavorable lighting conditions, its small size can make hitting it in the first place, from some distance, a hit or miss proposition.If this device had more competition, i'd dock it two stars for the red laser, small display of fractions, poorly written documentation, and perplexing UI (or outright dodgy implementation) with respect to some of the more complex triangulation functions. However, these things not withstanding, it's better than most of the competition, and awarding it only three stars would do a disservice to those reading this review. That said, in a couple years, the competition may have advanced sufficiently that a star downgrade might be warranted.
