GoPro has been expanding its line-up of action cameras to fend off an increasingly busy end of the gadget market. With the likes of Sony, Panasonic, TomTom and even mobile phone network EE looking to get in on the action, it's never been a busier time for GoPro.

The range of models has been expanding over the past few years, so you're faced with a tough choice when it comes to picking the right camera for your needs. There's plenty of accessories for all the models, thanks to that mounting system, but you need to make sure you have the right camera for the job.

Read on and we'll guide you through all the GoPro models and what each of them does.

Hero

GoProHero_0 copy

This is GoPro's most basic Hero model.

It costs $129.99 or £109.99 and supports up to 1080p (30fps) video, 5MP (5fps in burst) photos, and limited Superview. It also has an ultra wide field of view, waterproofing up to 131 feet, micro SD memory up to 64GB, and a 1180mAH battery.

The Hero offers the following video resolutions:

  • 1080p (30, 25fps), 720P (60, 50fps), and 720P Superview (60, 50fps)

Other features include: consumer-grade low light performance, various burst rates and time lapse intervals, and support for high bitrate video (up to 15Mbps) and auto low light. It doesn't support built-in Wi-Fi and Bluetooth, GoPro's Protune software, the night mode, simultaneous video and photo, continuous photo rates, auto image rotation, looping video, Micro HDMI, or an external studio mic.

We'll always recommend the Hero4 Black - purely due to its 4K-recording powers - as well as the fast frame rates offered elsewhere.

If money is a concern however, the Hero3 White is a more affordable alternative (and it's capable of shooting in 1080p). For $100 more than that, you can get the much more powerful Hero+LCD. It even has a built-in touch display. The only model we're most weary of is the Hero, simply because it lacks wireless connectivity.

The Hero4 Session, however, looks appealng, especially if you want to mount it on a helmet. It's smaller and lighter than others, so easier to manage, though the new Hero+ is even cheaper and still feature-rich, with Full HD 60fps video capture and more. 

But at the end of the day...and like always, it's up to you and your action cam needs. You can read more about GoPro cameras via Pocket-lint's GoPro hub. We also have a review of the Hero4 Black here.
