Any mechanic using inferior tools is sure to run into problems with being able to fully fix a vehicle they are repairing, so it is of the upmost importance to ensure that they are using the highest quality tools possible in order to ensure a quality diagnosis and repair job.

Troubleshoot With Ease

ODB2 scanners are highly useful tools when trying to troubleshoot problems with a car. With the data that can be provided from a car's computer, a fully-featured ODB2 scanner can help you find just about any issue, no matter how small or obscure it may be. However, with the complexity of some ODB2 scanners on the market, this can actually be more difficult to do than it should be, thanks to the lack of intuitiveness and overabundance of complexity that some of these devices seem to be loaded with. Furthermore, the ones that are easy to use sometimes are lacking some basic functionality that would help diagnose more complex issues. It is rare indeed to find a device that is both fully functional and easy to use.

The FOXWELL NT301 OBD2 Scanner gives you the best of both worlds by having an abundance of functionality while still remaining easy to use. The scanner itself has the broadest functionality, giving you a fully-featured list of tests and scans, while its management is more than clear and simple, thanks to the large and informative display. The Read / Erase DTC and I / M readiness hot keys allow you to use it directly from the package, without the need to go through a lengthy or complex setup process that seems to be the norm with some other scanners.

Practical and Durable

The FOXWELL NT301 autoscanner is a practical device, equipped with a large color display that gives you all of the necessary information in very easy to read text while providing a very intuitive interface. The body includes a rubber bumper that adds to its durability, a comfortable keyboard and a fast processor, which all help to make this device extremely easy to use. In addition, the device supports a huge number of cars equipped with the OBD2 connector, supplemented by a multilingual interface and lifetime free software updates, so there is no need to worry about this device going out of date as long as you check for software updates regularly.

If there is an actual downside to this device, it would be that the included USB cable is a bit short, which can make it difficult to connect to a computer for some people. Having said that, though, the ODB2 cable is plenty long enough to use it comfortably in most cars, including those that have their ODB2 ports in hard to reach places. At the end of the day, this ODB2 scanner will easily prove itself to be an extremely useful tool for diagnosing and fixing car problems thanks to its wide array of features coupled with its durable design and ease of use.

Easy Diagnostics

ODB2 scanners have been a real godsend to mechanics. Thanks to their ability to interface with the computer in almost any car, they are able to help detect issues with the car both quickly and accurately. However, many of the top models available tend to be pretty expensive, which puts them out of the price range for those who like to work on their own cars instead of relying on a mechanic. This, in turn, tends to take away the ability to quickly and easily detect issues with a vehicle. Not all of the top models are so expensive, though, and the Autel AutoLink AL319 OBD II & CAN Scan Tool is a great example of this.

This is an affordable and easy-to-use OBD2 diagnostic scanner that works on all models and makes of car from 1996 and newer.

The Autel AutoLink AL319 will assist users in verifying road tests, solving basic engine problems, checking the emission monitor status, resetting monitors, displaying and clearing error codes, and viewing freeze frame data.

Via a USB cable, you can connect the unit to a PC or laptop and have all the data about your vehicle displayed on the screen. This is one of the most affordable and yet, universal scan tools available in the market. The ability to connect it to virtually any PC makes it an invaluable tool for helping to track issues with any vehicle.

We are amazed at the value of the scan tool considering its very affordable price. Not only does this diagnostic device have a color LED screen, it’s also equipped with a built-in speaker, both aimed to provide a full (visual and audible) indication of car issues. By just the single push of a button, you’ll be able to quickly get all the required information of your vehicle's health right on the screen - the stored and pending codes, freeze frame data, the status of monitors, the status of MIL, manufacturer and generic specific codes and more. It’s one of those rare cases when you don’t really need to pay a fortune to get a quality device that will work just as expected.

 In short, those who are on a budget will certainly appreciate the convenience and ease of use of this ODB2 scanner.

What Is an OBD2 Scanner?

An OBD2 auto scanner is a lightweight, compact size and comparatively inexpensive auto diagnostic tool with built-in software, designed to continuously control a vehicle and inform its owner about all malfunctions in a real-time mode. This is a perfect device for both professional and custom diagnostics in service stations. Most customers give preference to using OBD2 scanners over other similar tools due to their price, compact size and simplicity of use.

Portable OBD2 scanners are commonly used for diagnostics of electronic engine management systems and other systems found in most modern cars. As they don’t require connection to a PC, they are handy to keep in a glove compartment and easily accessible to run a quick scan of a vehicle. The minor flaw of a thing is limited functionality. It’s only aimed to read and stream error codes on a display. A diagnostic scanner with a connection to PC may be a more beneficial purchase in this sense. Within the same price range, it offers much more functionality. On using a stationary PC or laptop, it’d be possible to access way more programming capabilities of such a scanner.

One other device that will certainly go no amiss is a jump starter. If you have not got one yet or look for an upgrade, make sure to take a look at our review of jump starters. With a jump starter at your disposal, a depleted battery won't be an issue for you whatsoever, no matter how far from your home you land.

What Features to Compare

Diagnostic Features

The first thing to consider when searching through a plethora of OBD2 scanners available is its diagnostic features. This is prime information that is gonna tell you whether (or not) a certain device will go with your car make. The cars manufactured before 1996 will not be compatible with any of the scanners on the market for the reason they’re not equipped with an OBD2 port, so, be aware. All scanners provide some built-in programming diagnostic software or a CD so a user doesn’t need to buy any special hardware. Diagnostic features vary a lot depending on the model of a device and a manufacturer (though, the plan is to extend functionality for more vehicles). However, there are certain things that are common for all - most OBD2 scanners are capable of updating their software and extending functional with micro-programs via the Internet and PC. These programs are usually easily found on the official websites of manufacturers and available for free download.

Connection Options

In order to update the software or stream data on a display, a scanner should be connected to the storage source via USB, Bluetooth or Wi-Fi. This is where you may want to consider available connection options of a chosen model and make sure that it will work for you as expected. Portable scanners are usually charged either via a battery or onboard power. Which one to choose will depend on what features you’d like your scanner provide. For example, if a scanner supports printouts, it may be a good idea to buy a battery-operated scanner. When compared to an onboard analog, it will provide an owner with more mobility options so that he can disconnect it and print out all the needed information on a car in any copy center.

Data to Display

The information on a car can be streamed right on a display of a scanner, smartphone or PC, depending on what option is supported by a device. Consider data to display feature and check what kind of information is gonna be displayed on your device - a short error code or a code with a definition.
