The Eachine EV300D is an appealing option as a budget slimline FPV goggles, with its unique “quad-versity receiver system”. Let’s find out what features it has to offer, and how it compares to other competitions on the market.
Where to Buy EV300D?
Specifications and Features
The New Eachine EV300D continues the unique “Dual Diversity Receiver System” and appearance from the popular EV200D, with a few improvements. Here is a summary of the specs:
- LCoS screens with 1280×960 resolution
- FOV: 42°
- IPD: 56-72mm
- Aspect ratio: native 4:3, can be switched to 16:9
- Adjustable Brightness and Contrast
- Focus adjustment between +3 and -8
- Supports Fatshark-style Diopter lenses
- DC Power input: DC 2S-6S
- Built-in DVR
- Supports HDMI (miniHDMI port) and AV inputs (3.5mm Jack)
- Supports 3D
- Built-in Anti-fog Fan
- Dual diversity – takes two external RX modules
Dual Diversity System
The EV300D is like the EV200D, it takes two external diversity modules, each can be equipped with two antennas, so you have a total of four antennas! However antennas are included, so you would have to get your own, and it’s going to cost you extra.
The good news is the goggles come with two removable receiver modules. But you can also install your favourite Fatshark-compatible receiver module in the EV300D. For the best performance, mixing different modules is not recommended, and 3rd party module should be used alone.
They are still using the traditional LCoS screens, not the latest OLED technology that the more popular brands like Fatshark, Skyzone and Orqa are now using. I expect OLED will be the choice for any top end FPV goggles moving forward as the user experience is better.
But LCoS screens still have a market as they are cheaper. And the screens Eachine is using have a higher resolution (1280×960) than the previous EV200D (1280×720), with a native 4:3 aspect ratio instead of 16:9.
And the good news is that you can switch to 16:9 from 4:3, but that would leave you two black bars on the top and bottom of the screen. Not only that, the EV300D also gives you display options such as Panorama, Zoom1, Zoom2 and Auto aspect ratio detecting mode.
The field of view (FOV) of the EV300D remains the same at 42° FOV as EV200D.
Eachine implemented a pretty nice OSD status bar. It provides useful information such as RSSI (signal strength) of all four receivers, current channel frequency, battery level, DVR status etc.
But it isn’t perfect in my opinion. It would be nicer if you can see the exact battery voltage, and how much free space is left on SD card. It’s still unclear how it works, but I hope you can adjust background opacity so you can see the info better, and the bar can be disabled by users or automatically hidden so it doesn’t block the view when flying.
IPD and Focus Adjustment
IPD range is pretty wide, adjustable between 56-72mm.
The focus adjustment is a welcome feature, and I’d love to see more FPV goggles to have it. Currently only the Fatshark HDO2 has it but I expect more manufacturers will adopt this in their future products.
Basically it moves the optics back and forth to adjust the focal length, and give you the clearest image for your particular eye sight without using any diopter lenses. But you can still use diopter lenses in the EV300D, and this is what they do better than the HDO2. It’s great for those who suffer from astigmatism, or if their eyesight falls outside of the adjustment range.
The goggles can be powered via the DC input between 7.4V and 28V, so you can use a LiPo battery between 2S and 6S to power the EV300D. Eachine also gives you a 2S 18650 battery case without the cells. It’s mentioned in the manual this case has built-in charging capability, so I suppose you can charge it via 5V USB.
And the EV300D can even be powered from the USB port!
The cooling fan in the goggles is powered directly by the power input, so you don’t need to plug in the balance lead like you do with most Fatshark goggles.
The built-in DVR has better specs than the Fatshark’s, file format is H.264 and I expect it to have higher bit-rate (better image quality).
Goggles firmware can be easily updated using SD card, or via the USB. It sounds similar to the Skyzone goggles.
The Eachine EV300D goggles even has a power button!
Is the EV300D Any Good?
The EV300D is only available from BG: http://bit.ly/2qdb5VL
If you have the budget, I would still recommend OLED goggles over others. I have yet to try the two top end OLED options: HDO2 and Orqa FPV ONE, as they are still not available as we speak, but I’ve ordered them! If you want an OLED goggles right now, I’d recommend the SKY03O for its performance and value.
I feel like the direct competitions to the EV300D are the Skyzone SKY03 and Fatshark HD3. In terms of features, the SKY03 is the clear winner, with EV300D as the runner-up. The SKY03 also has the sharpest non-OLED screens I have ever seen, almost as good as the OLED in the HDO.
Too bad the SKY03 has been discontinued and succeeded by the more expensive SKY03O.
Well, if you prefer a wider FOV, you want to look at the EV300D and HD3 anyway. They both offer a 42 degree FOV, which some would consider a lot more immersive. However the HD3 is a bit outdated now to be honest, as resolution and feature are not as good as the EV300D. And you are paying more! But mind you, you do get much better customer service from Fatshark, and that’s why you are paying the extra.
