What are FPV Goggles?

Flying drones from a first-person view (FPV) just isn't as fun without the right gear to make it really feel like you're right there on the drone. That's where FPV goggles or screens come in. Picking the right viewing device is key, since that's your window into the exciting world of FPV flying.

Let's start with how the goggles and video receivers work together. The video receiver (VRX) constantly gets the video transmission from the quadcopter and turns the radio waves into a signal for the goggles. This can be either PAL or NTSC analog video formats. The goggles then display those signals as the picture you see. Most goggles have the VRX built right in or have a spot to add one. The goggles often also have a video input port so you can connect the VRX separately with a cable.

FPV goggles come in two main styles: box goggles and low-profile goggles. Box goggles use one screen, while low-profile goggles have two smaller screens, one for each eye. The small screens are about half an inch each and use micro liquid crystal displays (LCDs). These dual-screen goggles tend to cost more since the small LCDs are more expensive to make. But with custom lenses, they can sit closer to your eyes for a more compact design.

Box goggles are cheaper to make since they only need one larger 4” to 8” monitor screen. While they provide a cheaper option, most people prefer low-profile goggles because they're lighter and less bulky.

Goggles also come in two aspect ratios: 4:3 or 16:9. 4:3 is more common since most FPV cameras use that format. But 16:9 goggles are growing in popularity as more people use high-definition digital video links from their drones.

The field of view (FOV) refers to the angle between the diagonal lines from your eyes to the edges of the screen. This ranges from 25 to even 80 degrees. Anything less than 30 degrees can be hard to fly with. Racers usually like 30 to 50 degrees, while freestyle pilots often prefer 40 to 50 degrees.

Taking care of your goggles helps them last longer too. Storing them in protective cases when not flying prevents the screen from getting scratched up over time.

As virtual reality and immersive experiences become more popular, the technology in FPV goggles continues improving too. Screens and lenses are getting better at things like color, sharpness, contrast, and reducing distortions. New goggles look much better than older models from years ago. As computer chips get smaller and cheaper, manufacturers can pack in more features without raising prices too much.

Since these goggles are your window into FPV flying, it's important to do your research and pick quality goggles. With technology always advancing, sit back and enjoy the ride! FPV goggles unlock a truly amazing aerial perspective, whether you're into photography, agriculture, or just exploring from above. Get out there and start flying!
