Launch Scanners (In-Depth Review 2021)

Launch Tech, the company behind Launch scanners, has been at the forefront of OBD2 scanning technology since 1992.

Since the brand began before the OBD2 standards were implemented, the company knows everything about it and helped develop some of the coding requirements for it.

It offers both DIY diagnostic tools for the car enthusiast and professional diagnostic scanners for shop and garage owners. 

Let’s see what the brand has to offer for automotive consumers and professionals alike.

Our Take On Their Units

As a step up from the CReader, this pro edition is much easier to use, thanks to the five-inch touchscreen.

This scanner is much more rugged and simplistic, making it an ideal choice for people who are more invested in their cars.

What also sets this scanner apart from others is that it comes with built-in apps, meaning that it operates much like a smartphone. In fact, it uses Android software to ensure that it works well in a variety of conditions.

As with other Launch Tech scanners, you can not only reset check engine lights but scan your car’s performance and see how well it’s running at any given time.

Technically speaking, OBD2 scanners are only meant to check your engine’s systems, as well as test for emissions. However, many modern varieties enable you to monitor other parts of your car, and the CRP129 is a perfect example.

In addition to check engine lights, this scanner allows you to inspect and monitor other systems like the oil, brakes, tire pressure, and airbags.

Coupled with a relatively large screen and a graphical interface, it’s never been easier to see what’s wrong with your vehicle.

The menu options are intuitive, and it covers almost all major car brands, so you shouldn’t have any compatibility issues.

This scanner model is another one that offers professional quality, making it an ideal choice for those who want to be able to diagnose and repair their vehicles at home.

First, we like that it comes with a rugged housing unit, making it tough enough for most environments.

As with other readers, this scanner can monitor additional car systems, like airbags and oil. However, what sets it apart is that you can not only live stream the data, but get insight into what could be causing the problem.

With most devices, you have to figure that out on your own, but this one makes it so much easier.

We’ve already seen some high-quality, professional-grade scanners from Launch Tech, but the X431 is one of the top models for aspiring mechanics. If you want a tool that offers a complete range of services and features, then this is definitely the one for you.

With a relatively large screen and the capability of scanning all of your car’s systems, it’s super easy to find out what’s going on beneath the hood.

What makes this device extra-professional is that you can also tap into your vehicle’s onboard computer system to spot problems and find solutions.

Overall, if you’re really serious about keeping your car in shape, this is one of the better scanners to buy.

The first thing that you’ll notice about this scanner is that it has a vertical layout and design, unlike the horizontal devices we’ve seen above.

For the most part, we prefer this style because it’s much more similar to a smartphone, which makes it easier to hold and read.

As with other Launch Tech scanners, this one allows you to monitor multiple vehicle systems, including the engine, brakes, airbags, and oil. It also comes with a vast array of makes and models and displays the information graphically so that you can see what’s going on much easier.

One extra thing we like about this scanner is that it comes with a lifetime of free, automatic updates. Thus, you never have to worry about it becoming obsolete.

If you like the layout and feel of the 9801 model, but you don’t want to pay as much, then this unit will be a better bet.

While you don’t get as much functionality with this scanner, it’s perfect for casual DIY car enthusiasts. Also, with the vertical, smartphone design, it’s much easier to diagnose problems.

This scanner has a vast library of makes and models, and it has an intuitive interface. What makes it less functional than the 9801 reader is that you can only check the engine and oil systems, and you don’t get updates.

Thus, if you’re serious about keeping your car in shape, you will lack some extra features.

However, as far as standard OBD2 scanners go, this one is still excellent and quite user-friendly.
