If you’ve never used an OBD2 scanner, you still might have noticed the Malfunction Indicator Light or MIL pop up on your dashboard. This tells you as the driver that you need to visit a mechanic. The mechanic will then troubleshoot with an OBD2 scanner in order to determine the exact issue with your vehicle.

Most likely if you’re here, then you’re sick of going to a mechanic and want to determine the true problem on your own. Luckily, OBD2 scanners aren’t overly expensive and are easy enough to understand.

The Best OBD2 Scanner

Let’s look at some of the best options on the market.

1. SEEKONE OBD2 Scanner

CHECK PRICE

The first option you might want to consider is Seekone SK860. Overall, this scanner has quite a bit to offer, especially function-wise.

Furthermore, the scanner can live stream numbers, graphs, and texts.

It even has several language settings available, including English, French, German, Dutch, and Italian.

The triple LED indication system for alerts and diagnostics is one of the main features that sets the Seekone apart from other OBD2 scanners in this price range. What makes this the best option is the fact that it is easy to use thanks to the one-click button system and the 2.8-inch display.

What to Look for in an OBD2 Scanner

Ultimately, finding the best OBD2 scanner isn’t a simple task. There are so many quality gadgets on the market nowadays. However, there are even more duds available. That’s why picking a high-quality scanner takes some careful consideration — and a bit of know-how.

If you’d like to find out what to look for, this best OBD2 scanner buying guide will help you find one that fits all your needs.

Type of Scanner

The first thing you need to consider before buying a scanner is what type you need. There are two types available:

1. Basic code readers
2. DIY scanners

1. Basic Code Readers

These types of scanners read the diagnostic trouble codes and are much cheaper than the other two types. However, they do not translate the codes for you.

2. DIY Scanners

Basically, DIY scanners have basic features and a few advanced ones, such as checking and clearing ABS, SRS, resetting oil service lights, etc.

However, DIY scanners are, in fact, more advanced than code readers since they provide you with the diagnostic trouble codes and even translate them. That means you can diagnose the problem and fix it on your own.

These scanners are far more convenient than basic code readers since you can connect the scanner to your PC in order to get a better overview of your data. Additionally, they tend to work much faster than the basic code readers.

Software

Every scanner needs compatible software in order to work properly. When you’re shopping for a scanner, check which model offers the right software compatibility, or else you’ll end up with a useless gadget that doesn’t work.

Keep in mind that some scanners need a computer in order to function, whereas others can connect to phones via Bluetooth.

Available updates

OBD2 scanners need updates that ensure your device is working properly.

When choosing a scanner, you need to check whether there are any updates available for that model. Usually the better scanners will offer free updates.

Functions

Ultimately, if you only have a basic knowledge of cars, there’s probably no need for you to look for a scanner with advanced options. All you need is a basic scanner.

However, if you know your way around cars, and you would rather try to fix the problem by yourself, you can always opt for a DIY scanner. These scanners can diagnose ABS, SRS, and transmission. Furthermore, most of them have data logging and a battery backup.

All in all, when it comes to features, it depends on how much information you’re looking to get from the device.

Corded or Cordless

Basically, corded scanners are the more reliable choice. They don’t require any phone connectivity since they have their own interface. However, most people seem to prefer cordless scanners.

To be fair, it’s quite understandable why that’s the case. First of all, you need to find a long cord in order for the device to function properly. Unfortunately, that means you have to deal with an annoying cord in the middle of your vehicle.

On the other hand, if you go for a cordless scanner, you run the risk of losing your Bluetooth connection.

Despite all this, the pricing is pretty much the same for both cordless and corded.

Budget

Unfortunately, budgetary matters are a bit more complicated. You may think that spending less money on an OBD2 scanner is more cost-effective. However, that’s not exactly true.

Though you may end up spending more money on a device than what you hoped for, you’ll probably save more on repairs. Obviously, even taking your car to the shop for a diagnosis costs money. If you have a scanner handy, you can see whether or not you can fix the problem on your own.

Conclusion

Buying an OBD2 scanner can, without a doubt, end up saving you plenty of money. Just think about how many times you’ve taken your car to the shop because you couldn’t figure out what was wrong with it. All those quick check-ups add up to quite a bit of cash!

Hopefully, these reviews offer some insight into which options are worth checking out. All in all, every product on this list has its pros and cons, so it’s up to you to pick one according to your needs.
