Here is a brief video from our friends at Airvuz that was published by TexusFU and talks to buying the right FPV goggles and gear right now.
Maybe not for everyone as he assumes that the buyer has the $300 to spend, (he tells us that his cost $315) but makes some good points about the technology that is in the goggles and suggests that you consider that you may enjoy the sport more and be more satisfied that if you were to purchase $60 dollar knockoffs. He also shows us a little about setting up the Fat Shark googles and some images of what you can expect after you get them up and running, going through the channels, and how it looks. The importance of DVR and some of other stuff that you need.
Worth watching if you are in the market, as it gives you some things to think about before you take the plunge.
