Darshan, what is your requirement and your budget for adding FPV gear?

@meet2ami    thanks a lot but what would you prefer for a newbie or beginner as like me or darshan, quanum or fatshark ?? because main thing is quality .. as i can buy both of them but if quanum goggles have same quality as like fatshark soo i would prefer quanum because in 15k we can setup fpv with quanum and on the other hand fatshark comes as a kit at around 30k +  (not a budget friendly) or we can say this it a one time investment in fatshark?    

is there any other option available in market for fatshark like copies of it or from boscom or any other good company under 20k ?

Well firstly tell us, have you built your multirotor? If yes how is your multi flying and how confident are you as a multi pilot? See flying with goggles on is not an easy task. You have to know the movements of your multi very well before going into fpv flight. So I would suggest 1st practice your flight with a lcd monitor where you can have a visual to both the multi and the live feed. When you are confident with that then move to goggles. Thats what I feel. And always fly in an open place with less obstruction.

yes i own a zmr250 and now i have an idea of all controls and  can do acro easily now soo there is no problem i think in doing fpv now and i have used couple of fpv simulators also for practicing

If you want to do racing stuff with your 250 size quad then video goggles are better option than monitor. Other brands like Skyzone goggles are available but even they cost a lot. Check the link and decide for yourself. But remember that the video what you get won't be HD.

Also check this youtube video with quantum fpv goggles put to test with 250 size quad. It might help you to decide.

Yes, if you are confident and want to go for racing, then goggles are better option. Start with the cheaper one's as suggested by phanivyas rather than the expensive fatsharks and skyzones. The quanum v2 is a good option to start with. Also you can use the 5 inch lcd display separately if you want.

Is this kit available in india?

thankssssss a lot ... @phanivyas and @meet2ami ...       will go with your suggestion

@nite You are most welcome.

@Darshan Not sure about the quanum v2 as shown in the video. But the older version is available. Here is one:
