DeWalt DWHT77100-XJ 30m Laser Distance Measurer
The Dewalt DWHT77100 30m Distance Measure from ITS is one of the most versatile, compact and tough distance measuring devices available on the market at the moment. With a range of 30m, this offers an pin sharp accuracy of only +/-2mm difference. The compact device, which can easily sit in a pocket, is particularly suited for internal measuring jobs such as homes, small offices and workshops. The DWHT77100 provides measurements for volume, area and indirect height with both 2-point and 3-point Pythagorean calculations. This is for when there is no clear line of site between where to need to measure FROM and measure TO. With your DWHT77100, you can measure two sides of a right-angled triangle, and it will work out the third with its built-in Pythagoras functionality. Similarly, you can get the height of a structure without even being next to it, just by measuring your distance from the base and from the top, and you can measure the width of a building by standing some distance away and taking measurements from there. Data is recorded in both Metric and Imperial and displayed on a clear screen. The overmould housing ensures a secure grip and slip protection, while the loop hole allows for attachment to a lanyard thereby protecting it against accidental drops.

Great bit of kit quite accurate within a couple of millimetres worth measuring a couple of times as different angles produce different lengths.

Works brilliantly, the only thing is that it was stated to be able to do Pythagorean calculations, which it can but it can only do it one way. I can't use it to find the hypotenuse of a right angled triangle, only one of the sides adjacent to the right angle. Obviously I can do that myself but I thought it was going to be a one stop shop and save me a few more pen/paper/calculator tasks than it does. Other than that I can't fault it.

I bought this to case out venues (often churches) where I will need to run cables, so that I know what lengths to bring when it comes to it. It saves loads of time and is a lot smaller and lighter than a 25m tape measure. Accuracy seems very good too. Brilliant device!

I have used this for sizing various rooms, alcoves and doorways and it has been a great time saver. Initially I checked the accuracy against a good quality measuring tape but after a few measurements I no longer check it as it is always spot on.I did try measuring a roof outside with it and found the laser got washed out by the ambient light but I expected as much so was not surprised. This and the fact that there is a minimum length it will measure are the only reason I gave it 4 stars.
Great compact, light Laser Measurer in a tough protective case that is easy to use and good value for money.The Measurer has good functionality with a range of easy to select metric and imperial measuring scales and is able to measure area and volume too. You can also select whether to measure from the front or rear of the measuring device.
Just what I needed for both a house and garden project.Measurements outside are better done when it's dull, however 6m to 10m in sun worked.Seems to be very accurate and saves messing about with a tape, especially when measuring over uneven ground or in tight areas.Really glad I got this and Tool Station had the most competitive price.
Definitely doesn't measure out to 30m. I've managed to measure up to 24m maximum and that took multiple attempts as it starts to find it difficult to read past 15m. Tiny little laser point which is almost impossible to see in daylight as well, I think the extra power of the 60m measures would help with that.But this is small, light, and easy to keep in a pocket all day around site.And batteries were included!
Handy pocket portable size measuringSystem, Once you master the processGood distance measurement, inside / indoor use , due to laser limitations
Nice compact unit buy not easy to use or navigate and almost impossible out doors - despite range of 30m as the red laser ight is not strong enough.
Top little tool this, works very accurately, saves cutting your fingers on the eld tape lease etc but I wouldn’t ever replace my tape with this- this is more suited to getting a gauge of a room length on your own where a tape would be impractical or too short. Good as a laser pointer too.
