It’s difficult to choose between these two cameras and a lot of it comes down to what you’re looking for in a camera. If you’re looking for something straightforward with decent video quality out of camera and easier operation, buy the M20. If you’re interested in a camera that can be tweaked and customized and has better audio, go for the Git2.
Summary: This is my favorite SJCam I’ve tested to date, with excellent daylight recording and a unique form factor. Aside from some needed improvements with the gyro and low light recording, this is a good option for those looking for a budget action camera.
The X2000 has tack sharp 2K video with good color and exposure. It includes a mounting system for drone and FPV use but is not compatible with most action cam hardware. The camera does not have a screen, but instead includes a 5.8ghz wireless video transmitter.
The AutoVox D2 is a cheap dash cam built with low quality internal components. The result is a device that has poor video quality and low reliability. I reccommend looking at the A118-C (link above) as it is known for higher quality video and better reliability.
