- GLM400C 400 Ft Blaze Outdoor Connected Laser Measure with Viewfinder, Includes 3 AA Batteries, Hand Strap, & Pouch

This instrument is a lifesaver! I bought it to survey the lot of the house I purchased, to plan for new construction. The lot has a large flat section, but also significant asymmetrical slopes in front and back. The back of the lot is not even easily accessible, but visible, with a steep downslope. I was able to measure everything in length and elevation pretty much perfectly, certainly well enough to be a guide for my preliminary building plans. I was able to measure the size and location of the house, setbacks, distance to the edges of the lot and flat parts of the lot, width of the street out front, etc. I used it in conjunction with a good target https://www.amazon.com/dp/B003BNY7NE?psc=1&ref=ppx_yo2_dt_b_product_details that made certain measurements much quicker and easier than without. A target like that is a must, IMO. The most impressive thing was that I was able to measure the back of the lot with a 40ft high, 70ft deep downslope (~32 degrees), with only a concrete drainage ditch at the end to target. I did all measurements form the top of the slope. The measurements, even with such an unreliable target, were repeatable enough and crosschecked well enough to be usable (within a foot). Ex: height should be the same when targeting the same point at the bottom of the slope from any part along the top edge of the slope. I got good enough measurements even without a tripod. Measuring the length, height and angle of the slope would have been pretty much impossible without a tool like this! The indirect measurements on this device are Just awesome! Quite easy to access in the menu, though easier would be better, maybe with a few more buttons on the face (it's also dumb that it doesn't remember settings between starts). It tells you the depth or height, but on the same screen it also shows the distance to the measured point (the hypotenuse of the triangle), as well as the angle. I wish it would tell you all 3 sides of the triangle at once. Of course the third side can be calculated using trigonometry or the mode can be changed to measure the other side (height or depth). The thing is amazing for measuring interior dimensions of rooms. So much quicker and easier than a tape measure! It also seems quite accurate at shorter distances where you'd normally use a tape measure, even at a few inches, though you can't measure less than about 5 inches in front of the lens. I checked against a tape measure and it was quite close. Having said that, it's good to have a tape measure along with this, as some measurements are easier and more accurate with a tape measure, especially at short distances. Long story short, this is an amazing tool that I wish I had known about a long time ago! But it's most indispensable for surveying.

So far, working very well. I chose the 400C model that uses AA batteries rather than the internal nonremovable rechargeable lithium cell. I use externally rechargeable NiMH batteries, to avoid the risk of damage from battery leakage. Accurate and easy to use. I have not used the Bluetooth features, with which some people have had difficulty. Beware that you need to push the small red button on the side to release the plastic reference post before attempting to remove the battery cover. The post determines whether the distance is being measured from the flat bottom of the unit, the middle tripod mount, the front lens, or the end of the post (in a corner for example).

This product is perfect for indoor/outdoor measuring. Extremely accurate. Easy to use and great functionality. Photos are clear to show what you’re measuring.

I can't recommend this enough to people that need to take precise measurements fast. Can't believe how many professionals don't have this. Yes tapes work, but if the span is over 13' and you are working at height and don't have a buddy this is such a time saver. Watch 2 dudes in a lift try to take a measurement for 30 minutes failing because they couldn't get their tape to reach without breaking and falling back to them like a limp ****. I had enough time to finish my task at height with the crane, get down out of my lift, walk to my tool box, grab my disto, get back to my lift and up to height AND take the measurements for them before they could figure out a way to take the measurements with a hard tape...Just saying it's a lifesaver when you need it. The camera comes in very handy when working during the day/in bright areas where it is hard/impossible to see the red laser dot.

I purchased this laser measurer for measuring houses and I have used many different devices in the past. First, the good:. The laser is easy to see in all but strong sunlight and even when you can't see the laser, the viewfinder camera is extremely helpful. The device has adequate functions for my needs (sketching houses) but the menu is a little clunky. The belt clip/holster is handy and well made. Now, for the issue: The battery life is AWFUL anytime you use the camera/viewfinder. I have had other distance measurers that last months on a set of batteries, even using them multiple times a day, but I find i have to change the batteries in this after a week or two of use if I use the viewfinder consistently. The screen also glitches occasionally and requires me to turn the device off and back on again to work. All in all, it's a decent device, but I don't think it's a good value for the cost.

Best in the world

Bought this not long ago. Initially just used it to gather live measurement data. Recently found the ability to capture the image showing not only the distance, but also the photo to show exactly where the measurement was taken. I've also used this with a long surveyor's stick to locate the survey markers on my property as I'm about to rebuild a fence and retaining wall. The measurement capability helped me quickly locate the survey pins - put in place 31 years ago.

The device itself is great and in the usual high Bosch quality. However the On Measure application has some drawbacks that made me return the item. I am highly dependent on being able to sketch the floorplan of a building I am going to measure, it is however not possible to import an existing floorplan in PDF or JPEG and quickly use it as a base for the new digital plan. And unfortunately - the sketch feature in the app is so sketchy that it was not possible to efficiently sketch even a 2500 sq ft office and place the windows. It should take under 5 minutes but I gave up after an hour. The IQ sketch feature is flawed, unreliable in detecting corners and angles. I took the extended plan but have cancelled due to these features being immature. Now, I don’t know what to buy.

I perform inspections where I need to measure the outside perimeter of homes (on occasion interior areas). This has performed well in all kinds of weather from bright sunny days to overcast/cloudy/snowy/rainy weather and has not stopped working. On brighter days, I do help by casting a shadow over the device with my notebook. Whether this helps or not I'm not sure as it still reads both ways fairly well. I've dropped it a hand full of times on different terrain (hard and soft) and it still functions no problem. It drains the batteries quicker than I'd like, but I do use it a lot during the week. Longer measurements do take a little bit to register (on low battery) so ensuring you have spare batteries available is recommended. I own the Bosch Laser Level (which came with the smaller laser measure which got wrecked and stopped working when my basement found it during some flooding), and loved both; and now this.

Good quality but camera outer class is a flexible rubber glass. Overall recommended

Es un producto de primera, tiene muchas cualidades que están sobre la competencia, lamentablemente mi equipo venía usado, no se si aduana lo abrió y armo para probarlo o era un producto devuelto, así que opte por regresarlo

EXCELENTE PRODUCTO, SIN NINGUN PROBLEMA... FUNCIONA MUY BIEN PARA EXTERIOR

Got this to work with MagicPlan (Ipad app). I was a bit skeptical for the price, but no regrets with the app compatibility aspect alone. Connected easily to it, and was wonderful during a big house move. We got the whole 3D schematic of the house within a few minutes and now know that it's accurate as well. In general, this was easy to use, and my dad was impressed. The different locations for buttons to make it measure was great for our bigger vs smaller hand sizes.
