Looking at your posts, do you fly a
Mavic 2 Pro? Do you use a
smart controller? I've owned a
Moverio BT-300 for over a year, the concept is the same as the BT-35e, and compared to the Samsung Galaxy Tab 8" tablet I used before there's no contest.
Moverio every time, no looking from VLOS to the tablet and losing sight of the Mavic if it's a long distance away,
besides which I found the tablet's picture was washed out in bright sunlight (I fly mostly in the tropics).
The main advantage to the BT-35e appears to be in dispensing with the
BT-300's "puck" controller which some users find a bit fiddly, especially on the occasions one might need to enter a password on the system, in which case using a mouse is the only way to go. The interface unit accompanying the BT-35e is a device many
BT-300 users would like to get their hands on but Epson currently don't sell it separately. The advantage seems to be its extra connectivity to devices such as the
smart controller or the
CrystalSky monitor via HDMI and USB-C, besides which, if required the ability to add extra juice via a power bank might be considered useful. Both the
SC or
CrystalSky screens are mirrored on the
Moverio glasses but I would suggest it would be much easier than the "puck" controller of the
BT-300. As far as being superior to for example DJI's
goggles, I would suggest so, as I used my
BT-300's when flying from a wooden jetty in New Guinea stretching nearly 100 metres from shore, only 2 metres wide and sharks swimming in the lagoon only 3 metres underneath me, one false step and I'd be in the drink swimming with them! Therefore to see & be aware of one's immediate surroundings is a big plus over the
DJI goggles and no need for a spotter!
That's my 10 cents worth and am hoping I can get hold of the BT-35e'
s controller from a supplier in North America who claim they have some for sale!
