The DJI Goggles, Racing Edition, have been discontinued by DJI, however, Dramatic Drones still has a limited number of combos available.
This combo includes an OcuSync camera and a CarryMore backpack. You can purchase it here.
The DJI Goggles RE are compatible with the Mavic Pro, Phantom 4 Series, Spark, and Inspire 2. These FPV goggles inherit all of the great feature of DJI Goggles, including full flight setting control, two high-resolution screens, Head Tracking, and more. An optimized facial pad and headband offer added comfort and better light blockage for a maximized viewing experience.
