I have been building Quadcopters for almost a year and its and been quite a journey and I have progressed a whole lot. FPV drone setup has always been my goal as this is what initially caught my interest after seeing the legendary Mr. Steele.
I recently bought a pair of EV100 FPV glasses from Eachine – I already had the Quanum DIY FPV Goggle V2 Pro but wanted to try something a little more agile. I knew that the Fatshark dominator 3 probably was the best choice, but I really wasn’t prepared to pay the price.
Eachine EV100 surely is priced quite aggressively and I paid only 98$ for these cheap FPV goggles, and to be honest I kind of doubted whether they would be a big disappointment – I bought mine after reading this review on Propwashed.
My first impressions on the EV100
The packaging is quite good, and it arrived from China without any damages.
The appearance of EV100 is somewhat plastic, but with a feeling of solidity and durability. The glasses are slightly less bulky than Fatshark or Skyzone.
The vision is based on 2 small screens of 720×540 pixels in 4:3 aspect, located behind 2 lenses. The FOV is 28 degrees and the lenses can individually be adjusted. You can also adjust the adjust the interpupillary distance (space between your eyes).
A little fan is located on the top that prevents fog on the small screens – this was not expected on such a cheap product and my experience is that it works.
On the right side you will find the battery connector – as you know it from Fatshark or Skyzone. Eachine provides a small Lipo 2s battery with a capacity of 1000 Mah (7.4V). I was a bit disappointed that the battery can’t be charged by a standard quadcopter charger. The ev100 battery can only be charged with a MicroUSB cable – some of you might find this convenient.
On the left side you find a 3.5 mm jack plug for an audio headset – there is also a video-in jack which is practical if you want to use an external receiver or video source.
On top of the EV100 you find two RP-SMA connectors for 5.8 GHz antennas. The ev100 is equipped with standard dipole antennas – I think you should discard these and replace them with cloverleaf antennas instead. For more information about choosing antennas see guide on FPVFrenzy.
Powering on the Eachine EV100
I admit that I was a little nervous the first time I plugged in the battery – would it work, or would it be the biggest disappointment ever.
Just plug the battery or a USB cable in, and the screen lights up. The OSD display is green and prints the frequency range and frequency.
You can easily change between racing and normal mode by pressing the main button for 3 seconds – racing mode is only necessary if you are racing with 5-7 other pilots.
If you press the main button for 6 seconds, another beep is produced, indicating that the auto-detect function is enabled. This is both practical and effective. The search is performed on 72 channels. The auto search is fast and all – but I think you will hate the constant beeping that can’t be disabled.
Pressing another 12 seconds deactivates the 5.8 GHz receiver and activates the “AV in” input.
So, what do I think?
The Interpapillary and distance settings in relation to the screens allow you to get a clear picture. I have a correction for farsightedness (hyperopia /+4.75) and I was surprised to be able to get a clear picture. But the picture on the screens is too small for and my eyes gets tired quickly.
RX reception is not as good as I had expected and my cheap external Boscam receiver is much better than the inbuilt in the Eachine EV100. The RC832 Boscam 5.8G 32CH 600mW gives me at least 25-40% better distance – so I am considering using this with the AV-in on Eachine.
You might be wondering whether Eachine Ev100 is it a diversity system since it has dual antennas? But no, if you look in the technical sheet you will be disappointed to see that a single receiver is just attached to two antennas – it does not switch between signal strength.
You can barely hear the fan, but it is effective in preventing fogging from appearing.
Some users have complained about the battery on the RCgroups forums, talking about losing one of the cell. I have not experienced this problem. I think it is very positive that the batteries are swappable between Fatshark, Skyzone, and many masks FPV goggles.
Conclusion and should you buy them?
The answer is not simple. Looking alone at the price it is a bargain with an integrated 5.8 GHz reception module, and the good quality-price ratio. EV100 is the best buy now.
I would therefore recommend them to you although they are not perfect. But only if you want to equip yourself with FPV glasses. For a similar price, the choice of an immersion mask may seem more relevant as it provides a much larger image.
Do you want to immerse goggles instead of a mask and your budget is tight? EV100 is a good choice. Otherwise, choose more advanced glasses and especially with a larger FOV, or a mask…
