CADDX VISTA HD vs DJI FPV Air Unit: Best FPV digital system

CADDX VISTA HD vs DJI FPV Air Unit: What are the differences?
#AD: Black Friday Crazy sales

Last year, DJI announced their first digital FPV system ecosystem which promised to provide the ultimate first-person view experience. DJI’s FPV system has 4 main parts: camera, VTX, goggles, and a remote controller. The biggest problem of their FPV Air Unit was its large size and weight, which makes it difficult to use it in smaller drones. While the CADDX VISTA HD is smaller, lighter, and $30 cheaper than the DJI FPV Air Unit, it provides about the same performance (range and latency).

Featuring the same DJI FPV camera with 1/3.2” CMOS image sensor and 2.1mm, it should be no difference, in terms of image quality, between CADDX VISTA HD and DJI FPV Air Unit.

Conclusions

One of the biggest downsides of the CADDX VISTA HD unit is the lack of on-board recording capability. It doesn’t have an SD card slot like the DJI Air unit. The only way to record footage with the Vista is with your DJI Goggles.

For sure, the biggest advantage of the CADDX VISTA HD over the DJI FPV Air Unit is the smaller size and lower weight. With 20×20/25.5×25.5 mounting holes can be used on smaller Toothpick and TinyWhoop style FPV drones.

Despite that the VISTA HD VTX has only one antenna input, it promises the same range as the DJI FPV Air Unit with two antennas.
