NWI NSLP500B Siteline Transit/Level Package – 20X Magnification, 200ft Range, ±45° Transit, 1/4" Accuracy at 100ft

After reading the reviews on this I decided to buy anyway since I have excellent knowledge of how to work with this equipment. I was able to check the calibration as soon as I received it in the mail. No issues from shipping. Just finished all calibration checks and have determined that is within specs. I’ve been surveying property and building structures for 40 years now and have determined this meets and exceeds all my needs. I’m surprised for such an inexpensive piece of equipment that it’s as accurate as it is. I don’t know why others have had issues? This works just as good as the more expensive that I’ve used in the past. My only issue is that I’m out of practice trying to do the math for gps coordinates and distances. I have to refer back to my books to remember but with time it will all come back to me. This is an excellent buy for what you get and how it works. Everyone should realize this is a transit and not a builders level. Two entirely different things. Both have distinct uses and different functions. Make sure you get the right one for your needs. I also found that when I was setting fence lines, I was able to shoot distances up to 600’ within a quarter of an inch accuracy. I haven’t shot my quarter mile line yet, but know that I’ll have to shoot at two different points and still be within a quarter inch. Anyone that doesn’t have the knowledge to use this should study up before you use and write a review. That way you’ll know precisely how this works and won’t be disappointed if you have the knowledge.

First use was to check grade for installation of 18×33 above ground pool. Easy to set up, easy to focus and find measuring device. Will continue to use through-out pool set up and let you know more later. Equipment is not el-cheapo but well made and functional. Takes the guesswork out of my projects.2 years later and still setting up pool.Spent almost a year fixing mom's house up after she Died. I'm 72 yrs old and what you see in picture i've done myself so it takes awhile.I have set up this transit at least a dozen times in my pool base project so far. Every time i have there has been no problem at all. Leg clamps work fine. each time i set it up, i check my previous work and it comes out dead-nuts every time. i love this thing. I know, "made in China" but seriously, Who sent all this stuff to be made in China to start with? "American Corporations." Sorry, don't mean to offend.

The Tripod is lightweight but has decent lock-up. The Transit as a Level is accurate within 150-175 feet to the quarter of an inch. As a Transit, the Horizonal Dial cannot be adjusted more than to a half degree, and that with only REALLY GOOD EYESIGHT. I shot Stadia and found the transit to be accurate within a foot at 250-300 feet (horizonal). Easy three-knob adjustments for leveling on the tripod head. The Level Rod is VERY LIGHT DUTY, but taken care can last a good while. The plastic snaps are sufficient, but not likely durable as metal ones. Similar in design to the 'david white" instrument, however the Optics are very cheap and CANNOT be used in very "low light" scenarios. I would have paid the extra 100 bucks for a "dw" brand if I'd had the opportunity to try this out. Overall a decent occasional use Transit Level.

I just received today I've looked it over read the book exactly what I wanted I've done construction 30yrs ---- not the best one but for home & light construction I'm glad I have mine

If your needing one for basic purposes you can’t beat it. If your needing one for more complex work, this maybe the I’ve for you as well. I only use for basic leaves reads.

I got this to figure elevations for a new garage and it worked great! Follow their directions on how to level the unit and it’s easy to do. I tried to do it my own way first and I struggled, but had it perfect within just a couple minutes once I looked at the directions again. I was more than happy with the quality feel of the product. The measuring stick was very easy to read very accurately.

i would buy this again well built

I followed the instructions in the manual with regard to checking the accuracy and found that even brand new, right out of the box, it was about 3/4 inches off at 100 feet. I was able to re-calibrate it myself so that the accuracy was less than 1/4 inch off at 100 feet (which was good enough for what I needed) but it was a major pain in the ass as the adjustment screw is tiny and extremely hard to get a wrench on. In the end it does work and this was a less than half of what a nice David White unit would cost so you get what you pay for. Once calibrated it worked fine. I do wish it had 4 adjustment screws rather than 3 as it takes a little longer and is slightly more complicated to set up in the field than a David White unit with 4 adjustment screws.
