Foxwell NT650 vs NT510 – Which plug and play diagnostics scanner is easier for use with minimal experience?

Are you a DIY enthusiast who is looking to get more hands on with your auto repair and maintenance? This Foxwell NT650 vs NT510 comparison looks into two great options.

After my retirement, I had so much time on my hands. I worked in the same suburban area where I live so I didn’t have any use for my car. In fact, I had used it only about twice a month for the last decade. It was in such great shape that I didn’t need to replace it. However, after I started using it more frequently, I noticed a higher likelihood of my check engine light acting up. With the help of my grandson, I looked on the internet for a solution and found this great Foxwell NT650 vs NT510 comparison.

Foxwell NT650 vs NT510 – how do they differ?

Display and interface

The larger display on the Foxwell NT650 makes it very appealing. It has a 4.3” screen, which offers both textual and graphical data. In contrast, the Foxwell NT510 has a slightly smaller 2.8” display. Both models display freeze frame and live data, allowing for accurate diagnosis. The button arrangement of the NT650 offers better value than that of the older NT510, with a more practical and effective layout making the scanner much easier to use. This model is virtually work-free when compared to the older model, with a great layout enhancing the high end output. The interfacing of the NT650 tops that of the NT510, with a greater setup making it easier to use. While both scanners will offer great diagnostic value, the NT510 will be markedly tougher to use at first. That said, the difference in build is only marginal, with both scanners offering great diagnostic value for cars they are compatible with.

Diagnostics and support

Alongside the comprehensive OBD2 service modes, both these models offer a range of additional services that improve the quality of assessment such as odometer calibration, EPB, TPMS, gear learning, SRS, CVT, BRT and ABS resets. However, the NT650 will not provide ECU information. Even though the NT510 is marginally smaller than the NT650, it presents impressive live data graphs for thorough diagnosis. It offers single and merged presentations to help users stay ahead of their vehicle’s needs. The high quality output runs through different diagnostic aspects, which makes the model stand out. The NT510 will offer engine, transmission, airbag, ABS, CVM, DISA, DME, GSR, EGS, SZL, EPS, SAS, DSC, TPMS and CAS functions for thorough vehicle diagnostics. These scanners will offer multilingual support, provided that users contact their providers before making their purchase to customize it to suit their needs. They do not support multiple languages simultaneously. However, the NT650 supports more languages than the NT501 including Korean, Japanese and Thai. Both models are designed to suit the diagnostic needs of every customer, with each model able to be customized to meet different requests. The NT650 and NT510 offer lifetime free updates, which should ensure value for new vehicles releases. Still, for drivers who won’t consider updating their scanning tool, the NT650 may offer better value for newer models than the NT510. The newer model is bound to be a better fit for later releases, but an update, which the brand offers for free, will work to balance this out. For much older vehicle units, the NT510 will work better than the NT650.

Impact protection and build

An ideal scanner should be sturdy and durable. Both these models feature a rubberized coat that is designed to offer impact protection, limiting damage even in the event of a hard fall. They are designed to sustain drops of up to 15 feet without any damage. This will ensure that your scanner can offer diagnostic services for a long time. The impact protected outer coat may be similar, but the hardware within either scanner is markedly different. The NT650 overpowers the NT510 with a better processor, more storage capacity and better working memory overall. With an 8Gb storage card instead of 2Gb, 1Gb running memory instead of 256 Mb and a 9X35 processor to replace the 9G10 version, the new scanner will run faster for efficient services. The NT510 measures 8.7 x 6.6 x 3.4 inches while weighing in at 1.8 pounds, while the newer model comes in at 13 x 9.2 x 3 inches and 3.15 pounds. The NT650 maximizes on the larger size to offer a better build overall, with a wider screen and more dynamic button arrangement as we’ve discussed. That said, the more compact NT510 will be easier to store, transport and use, thanks to a smaller build. Even though the NT510 is lighter and smaller than the NT650, it will not offer similar value for the most recent vehicle releases without an upgrade, which can be accessed freely through the unit.

Bidirectional and other special tests

The Foxwell NT650 will not run bidirectional tests, and may be shorthanded compared to the brand’s other fully operational scanners. The NT650 is not marked as one of the fully functional scanners, even though it offers impressive diagnostic services. If you are planning on running this type of diagnosis, then the NT510 might be a better choice for your needs. The NT650 is not compatible with some electronic systems either, although it works well with a large number of options. You will need to find out whether or not it is ideally fit for your motor before purchase. The alternate NT510 offers impressive bidirectional testing, as well as a number of other services. This older model is designed for thorough diagnostic value, even though it offers a lesser build. Both scanners will offer high quality services that will help car owners maintain track of their models, but the older model might be overall a better fit for thorough diagnosis. That said, the NT650 is a value for money choice that carries out ABS, ABS version, actuator and auto bleeding tests, as well as a few other special diagnostic functions. It matches the NT510’s range of options, and offers great value for new models even without an upgrade. While it may cause some compatibility issues for certain needs, the new scanner will live up to most users’ expectations. The NT510 will be a great overall choice for the diversity of diagnosis options on offer, with the model being well suited for OBD1, OBD2 and EOBD scanning for multiple vehicles.
