Skyzone SKY01 5.8GHz 40 Channel Head Tracker FPV Goggle

This is the latest generation of Skyzone goggle with 5 bands 40 channels, including the new race band channels.

It comes with ISM 5.8GHz 40 channel diversity receiver, working in diversity mode to achieve good signal utilization and improve image quality.

The Benefits of Goggles with Diversity 
A diversity system uses two different video receivers, and two different video antennas. This gives you a better chance of receiving a clean and unobstructed signal. These are connected by a diversity unit that chooses the best video signal. You could mount one of the stock antennas vertically and one horizontally. For best results you want to use different types of antennas. This gives you the option of using a long range directional antenna for one receiver and a non-directional antenna for the other. The diversity system automatically chooses which antenna is receiving the best signal at any moment. 

External Camera 
The 640x480 external camera was added to allow you to do things without removing your goggles. When you have to pull your goggles off you have the issue of your eyes adjusting to the external light. You also have to physically remove the goggles or situate them on your head so they don't fall off. The external camera allows you to keep the goggles on for small jobs and landing. The lens on the external camera does seem to make things look farther away. 

5.8 Diversity Unit
These goggles have a built-in 10 channel/5 band 5.8G diversity unit. This allows you to use this unit with most FPV 5.8G transmitters on the market. 

Dual Receivers & Dual Antennas 
The unit comes with two vertical omni stock 50ohm antennas with SMA connectors.

Monitors 
The goggles have dual 854X480(WVGA) monitors with 1,229,760 color sub-pixels.

Head Tracking
These goggles have built-in self calibrating head tracking that utilizes a gyro. 
-PPM Channel Setup
-Pan Tracking Range Setting

NOTE - If you use the Futaba trainer plug you can power the goggles that way (no external lipo needed). 

LiPo Powered
A nice feature with these goggles is that just about any 2-6S liPo you have can power them. The input power plug accepts voltages of DC 7- 28v/1A. I find that a two or three cell liPo does a good job.

FOV (Field of View)
The SkyZone goggles have 30 degrees (diagonal).
