Feature Resolve every obstacle with a 1280×960 LCoS microdisplay and 42° FOV. The Japan-sourced Citizenn panel packs 2.3 million pixels at 4102 PPI into a native 4:3 aspect ratio, switchable to 16:9. This pixel density resolves thin branches, gate edges, and ground texture that budget box goggles simply miss — giving you the visual confidence to fly tighter lines without hesitation. Eliminate signal dropouts with dual true diversity receivers. Unlike single-receiver designs that switch between two antennas, the EV300D runs two independent receiver modules across four SMA antenna ports simultaneously. The system continuously compares all four signal paths and locks onto the strongest feed in real time. Behind concrete, dense woodland, or at crowded race meets, this redundant architecture keeps your video link stable where others fail. Correct your vision optically rather than wearing glasses inside the goggles. IPD adjusts from 56mm to 72mm, wider than most competitors. Focus compensation spans -8.0 to +3.0 diopters, covering myopia up to -800 degrees and hyperopia up to +300 degrees, as well as astigmatism. This eliminates the discomfort of cramming spectacles into a faceplate and removes the risk of double fogging or scratched lenses. Prevent lens fog with the built-in active circulation fan. Moving between air-conditioned spaces and humid outdoor air creates condensation at the worst moments. The fan continuously moves air across both lenses to stop fog from forming — a small engineering detail that preserves your vision during race starts, long sessions, and rapid temperature shiftss. Power from your existing flight packs and record every flight. The 7.4V‑28V DC input accepts 2S to 6S batteries; use the included 18650 case or any spare LiPo. The H.264 DVR captures 30FPS footage to a microSD card up to 64GB (not included) with real‑time RSSI, battery level, and recording status overlaid on screen. Mini HDM1 input enables simulator practice on the same display, while 3.5mm AV and headphone jacks offer flexible audio and external video connectivity. The 5.8GHz receiver operates across 5333‑5945 MHz with ≤‑93 dB sensitivity, meeting CE compliance requirements, and firmware updates via SD card or USB keep performance improving over time.  Key Features * 1280×960 LCOS HD DISPLAY: Japan Citizenn panel, 6.3μm pixel pitch, 4102 PPI.
