Walksnail Avatar HD Goggles X
The latest and greatest goggles from Walksnail for the Avatar system. Lighter and much more comfortable than the first Walksnail goggles. 50 degree FOV and support for 1080p100 video from any Walksnail VTX. HDMI in and out, bluetooth and wifi connectivity with a companion app coming soon. If the Walksnail system is for you these are the goggles you'll want.
Walksnail Avatar Digital HD FPV Goggles w/ Patch Antennas
These goggles from Caddx offer a premium experience with the Walksnail system: 100fps, OLED screens, and a comfortable fit (for me at least). The navigation joystick for the in goggle menus can be a little imprecise.
Best value digital
EMAX Transporter 2 HD 5.8GHz FPV HDZero Goggles
Great value box goggles with removable screen for the HDZero Digital system. This brings the cost of HDZero right down and in line with many analog systems. Perfect for racing and freestyle.
Top of the Line
There is a lot to like about these goggles: They are the most comfortable (for me) with a very intuitive user interface, they have the lowest possible latency for HDZero, They are excellent for analog as well as HDZero and even offer 100 fps for the Walksnail VRX.
Value add on
HDZero VRX - Digital HD Receiver Module
The HDZero VRX module provides a low cost way to experience the HDZero video system on existing goggles. However, you won't achieve the lowest possible latency with the VRX due to HDMI input lag. If you're a racer you'll want to save up for the goggles.
