Before selecting your OBD2 scanner it is necessary to consider its primary purpose. If you require this scanner for professional use you may wish to spend a little more on a model that has a more expansive range of features.
If you are likely to be using this scanner to carry out occasional checks or to investigate the cause behind a mysterious engine light appearance, you may wish to invest in a more basic model.
The market offers two different types of OBD2 scanners. The first is a handheld tool that utilizes a cable connection. It has a screen, buttons, computer chip and software which allow for easy use. The second is a scanner that uses a Bluetooth or wifi connection and is possibly the more modern option available. This type works via a wireless transmission and is connected to the Bluetooth setting on your phone.
Both have their own advantages and disadvantages. While a Bluetooth scanner is smaller in size, there is a great risk of disruptions from a poor wifi connection or insufficient battery power from your mobile.
Some may find a handheld scanner easy to use with less risk of technological disruption. The market offers many high performing options for both models that aren’t overly expensive.
Of course, the scanner that you choose must be compatible with your vehicle. The majority of modern scanners are compatible with most vehicle models.

Before making your purchase it is important to pay attention to the specifications of your product to ensure that it is suitable for you with a wide range of vehicles. This will allow you to avoid disappointment upon receiving your scanner.
The functions that your scanner is equipped with can vary between brands. Almost all can digest your cars onboarding computer codes and check the engine to identify potential issues, however, others will be a little more expansive.
These scanners can provide correct mileage readings, reset the emissions monitor, and much more. You may not require all of these functions so it is important to evaluate your primary requirements before making your purchase.
If you are a professional or simply a car enthusiast you may find these functions beneficial in allowing you to conduct more thorough tests.
Ease to use
Ideally, your scanner should be easy to set up and use. You don’t want to be faced with the issue of being unable to connect the scanner to your vehicle as this is going to prolong the amount of time that it takes to get to the source of the issue.
If you are unfamiliar with using this kind of scanner the different codings can be difficult to understand. It is beneficial to opt for a product that caters to those who are beginners to this kind of scanner.
For those that have used an OBD2 scanner previously, this may not be a significant issue. Also, ensure that the screen displays the results clearly. You don’t want to select a scanner that displays the results in a complex manner.
It is necessary to ensure that your scanner is equipped with detailed instructions if you are a beginner as this will make it much easier to set up and use.
Your scanner is only going to be useful if it provides you with accurate results and readings.
An OBD2 scanner that provides you with incorrect information is going to be a particularly worthless purchase and isn’t going to come in handy when trying to diagnose issues with your vehicle.
Scanners are available in different sizes although they often conform to a similar shape. Some may find heavier and bulky scanners inconvenient meaning that they spend more time inside your home or toolbox than the car itself.
This isn’t going to come in very handy when you find yourself requiring the use of this scanner midway through your journey.
Most scanners are designed with a durable exterior which provides greater resistance to damage should they happen to be dropped. The material construction is often a reflection of the durability.
If your scanner is cheaply made it is likely to become damaged faster, resulting in a more immediate deterioration of the quality.
Ideally, if your scanner uses a cable connection the cable should be thickly constructed as this is going to make it much more durable.
It is beneficial to opt for a product that is covered by a warranty. A warranty provides you with support and a rectification of any issues with a faulty product or if you are dissatisfied with your purchase.
A warranty can also provide you with greater assurance and confidence in the brand and the product.
OBD2 scanners can vary significantly in price. While some come with hefty price tags, many options are much more affordable. If you require this scanner for professional use you may wish to invest a little more into a high end product.
Likewise, if you require this scanner for occasional use, you may prefer to invest in a more affordable option. We have included a variety in our guide above to highlight the options that are available to you.
The length of the cable
If your scanner functions via a cable connection, ideally it should be long enough to provide you with the flexibility to work around your vehicle.
One that is shorter in length is going to be a little restricting and may provide difficulties when attempting to diagnose an issue if you are not able to reach the area freely.
