Review: It's perfect for drawing straight lines - This little guy is very handy and sufficiently accurate for the price. It's a decent budget transit. It's perfect for drawing straight lines, but it has some accuracy problems for other tasks: 1) The level on it isn't mounted correctly. I can get it so that it's perfectly level facing north and east, for example, but then it's slightly off facing south and west. If I correct south and west, it's then slightly off facing north and east. Essentially, it's not possible to get it level in four directions, which could spell trouble for spotting accurate elevations. However, as long as I'm only leveling in a 90º range of motion, it's fine. 2) There's something wrong with the degree markers on the bottom. If I draw a straight line with the transit, zero the gauge, and then turn it exactly 90º and draw another straight line, the lines are only 89º apart. I'm not sure how, but that's what I've observed over and over again. Makes it pretty useless for surveying corners of buildings or anything that requires a precise degree measurement. Review: Do not buy for straight - Bought this to build a fence. We got everything square with the house using 6 8 10 method. Squared transit to zero with that. Went 90 degrees and put a stake. Went 180 degrees and put a stake. We pulled a string just to make sure. Wasn't even close. Had the blum bob under transit and it was 10 inches off. On 30 foot set at zero it moves 2 inches either way and is still at zero. That's is not close on that distance. I would send it back but I didn't test it when I order a few years ago. It did however work good for horizontal level. I should have spent more money ## Features - Siteline Transit/Level - 20x Magnification - Leveling Accuracy: 1/4 in at 100-Feet - Working Range 200ft - Includes carrying case, plumb bob & manual ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000KB43RA | | Best Sellers Rank | #224,522 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #400 in Levels | | Brand | NWI Northwest Instrument | | Brand Name | NWI Northwest Instrument | | Customer Reviews | 3.9 out of 5 stars 8 Reviews | | Global Trade Identification Number | 00088688101233 | | Included Components | 1/4-Inch Collet | | Manufacturer | Northwest Instrument | | Material | Metal, Plastic | | Material Type | Metal, Plastic | | Operation Mode | Manual | | Style | Accuracy: 1/4" at 100 feet | | Style Name | Accuracy: 1/4" at 100 feet | | UPC | 088688101233 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** NWI Northwest Instrument - **Material:** Metal, Plastic - **Style:** Accuracy: 1/4" at 100 feet - **Operation Mode:** Manual - **UPC:** 088688101233 ## Images ![NWI NSL500B Siteline Transit/Level - Image 1](https://m.media-amazon.com/images/I/714GJNV9xaL.jpg) ![NWI NSL500B Siteline Transit/Level - Image 2](https://m.media-amazon.com/images/I/41IG9gqjuCL.jpg) ![NWI NSL500B Siteline Transit/Level - Image 3](https://m.media-amazon.com/images/I/716ZC-8UlaL.jpg) ![NWI NSL500B Siteline Transit/Level - Image 4](https://m.media-amazon.com/images/I/71Gb0sfNQxL.jpg) ![NWI NSL500B Siteline Transit/Level - Image 5](https://m.media-amazon.com/images/I/7162s5KJ0pL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐ It's perfect for drawing straight lines *by N***S on September 14, 2014* This little guy is very handy and sufficiently accurate for the price.

Furthermore, please learn the difference between a transit and a builder's level for the sake of searching out one or the other. ## Frequently Bought Together - NWI NSL500B Siteline Transit/Level - AdirPro Bubble Level for Aluminum Builders Grade Rod - Ensures Upright Rod Position - Compatible with Leica, Topcon, Seco, CST/Berger, Johnson, Nedo, NWI and More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/23624686-nwi-nsl500b-siteline-transit-level](https://www.desertcart.be/products/23624686-nwi-nsl500b-siteline-transit-level) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-09*
