With the
MA2 you have a couple relatively (or dirt cheap) alternatives.
First the cheapest route. VR
goggles. You can get a relatively decent set of VR
goggles for under $30. You can fly in split-screen FPV mode with Litchi or another program DroneVR (drone). I think Litchi is under $25 and DroneVR cheaper still. I went that way first and found that with a few mods (because of presbyopia and fit) I could make them work.
The second way, more expensive but more universal is the DroneMask/MagiMask now at $170. These
goggles don't use split-frame and can be used with the Fly or Go4 apps main screens.
The downside to those is that you have to access your phone and set the settings before you seal them in your
goggles where access requires taking them out of the
goggles. I have both and have just started testing the DroneMask. I took an exterior photo of both
goggles together. With the cheap VR
goggles you can see from the photos that I had to add nose pads for comfort and support, install reading glasses to allow me to focus fully and put pads on the mounting surface to move the phone further away, to again, aid in proper focusing. Truth be told, the cheap VR glasses, with mods are easier on the nose and face as the DroneMask, when adjusted for focus, by extending the phone area outward increases the weight leverage on the face. I may install readers in these too, but not yet.
The one better thing about the DroneMask is the way the mounts in in one position of the headset compared to the VR set that I have with no stationary mounting.
While a bit heavier than the Pecosa VR set that I have (left image) I think I would now recommend a set that has a slide-out mount which makes it easier to access your phone and reinstall it in the exact same position. I got the Pecosa set because it is lighter than the the "Next" set, featured in the last image.
If you want to experience FPV from you DJI camera drone without
DJI goggles, you can. I probably shouldn't have purchased the DroneMask as I already have Litchi and DroneVR... But again I have them and I'll test them when I can get outside in open space.
