+ 1 x Eachine Goggles One
+ 2 x 1000mah 2S LiPo with DC connector
+ 1 x USB-microUSB charging cable
+ 1 x 5.8G linear antenna with SMA connector
+ 1 x Fresnel lens clearning kit
+ 1 x Instruction manual (English)
The general design is inspired from the Headplay/skyzone model. A large and lightweight foam stucture with a HD screen and a Fresnel lens.
The top part is very similar to the Headplay
The battery strapped but here a classic DC round connetor
To turn on/off the goggles, just long press more than 4s the “autoscan” button. The total boot takes 5-6s before to see the whitesnow on the screen, synonym of FPV friendly screen firmware. One turned on, the same button but pressed only 2-3s is lunching the autoscan procedure where first all the 40CH are scanned and the most powerful (in term of RSSI I guess) is automatically selected.Here no possibility to select manually the Vfreq.
The list of the 40CH supported Vfreq subdivised into 5 bands
The distance between the fresnel lens and the noze section is rather low IMHO.
By consequence, even for “young” eyes, when you wear the goggles,the image is little bit out of focus. Paradoxally, with some correcting glasses, everything is fine but….the goggle ones can’t accept large model of vision’s glasses.
A sponge is added and the goggle one is confortable to carry
The SMA connector is positioned below the main plastic canopy structure.
A basic 5.8G linear antenna
By consequence it’s hard to insert and to remove the antenna. You need to pinch the basis of the antenna while screwing it
427g without battery so just 7g less than the skyzone SJ-V01 (434g).
Close to 500g with the LiPo attached
The image quality is great … full of detailed. Color rendition really good
but the battery voltage indication is very hard to read and more ….. for PAL sources, the image is cropped mainly on the bottom part (see video). Like the system stays in NTSC whatever the PAL option is turned on via the menu
since there is no buzzer or other voltage alarm, it can be a problem. The Goggles are shut down if the battery go below 6.9V.
I noticed after a brutal stopping (voltage drop or by disconnexion of the battery), the goggles can sometime not reworking in the sens the video receiver part seems to not rebooting. After a couple of minutes, in general, everything is ok. It’s a kind of “black screen of the death”.
The latency is acceptable for most of FPV usage (~ 100ms)
UNBOXING & ANALYSIS
A frustrating situation with the goggle ones…. because in one hand, the 5″ screen is really beautiful and precize, the goggles structure design nice and a pretty good RX sensitivity but in another hand the firmwares of the builtin VRX & OSD need huge improvements and addings: current Vfreq must be displayed, manual Vfreq selection must be added, as well as the an AVin/out and PAL issues for the priority first improvements. Of course a diversity and a builtin DVR will be great too. If you can live without manual Vfreq selection and always thrust the Vfreq scanning button, the goggles one can be for you. In anycase,I am sure, they will updade/fix these first lackings for new batches. Since ther is no USB port, no hope to flash new firmwares (at least easily)
+ Super quality screen
+ 1080P resolution
+ Good RX senstivity
+ HDMI input
– No manual Vfreq selection, only via the scanning procedure
– No OSD informations about current Vfreq
– Not focused for perfect eyes
– Hard to fit with glasses
– Antenna hard to tight
– No diversity
– No AVin/AVout
– No buzzer of voltage alarm
– Potential “black screen of the death” when the voltage drop below 6.9V
– PAL source cropped
