My 2cts:
where I live (Japan) there is lot of accidents of drones (now 90% of the japanese heritages areas put warning on their entrance concerning DRONES: NO FLIGHT, the others 10% will stop you when you will open the bag to pull out your drone)
in any case the policemen dont know about drone and so when they come you are good to spend 2 hours to show that the area is not "no flight" that you have a pilot licence from government, that you have the agreement from the city, prefecture or whatever!
Anyway, when you pass all those problems
and then you speak to responsible of temples and sanctuaries who allows you to shoot, when you show them how goes the real sense in a front of a building, they are impressed and very very confident straight after! for me it is priceless to see them happy and peaceful
(keep in mind they never ever see a drone flying in real, and what they know on TV about drones are quad ones, insecure, and tiny size competitors, for them it is impressive to see a Yuneec with the remote the bag pack etc)
Anyway as others said: dont trust at 100% the real sense, YES it is super helpful, YES it is a kind of copilot which lock the move if you make a mistake or didnt consider an obstacle on the front
but NO it will not secure your flight for YOU at 200%
Also as it is written it is FRONT only
to coming back to the H PLUS and real sense v2, as I dont know for the V1
on the manual of the H PLUS it is clearly described that the real sense uses also the camera to manage the recognition so my question is: how if the camera has angle? does the covering area of the real sense (sonar + real sense + camera is clearly increased? or no)
