You can move the camera up and down to a degree with the vision. With the plus, you have greater range. You can also add a new gimbal to the vision like the Rotorpixel and have full range. With my P2V and RP gimbal I can look straight down.
Both Visions give full telemetry in the display of your phone.
I bought a P2V a year ago and added the RP gimbal three months later. Still flying!
I just bought a second USED P2V and outfitted it with the RP gimbal. It's a solid setup.
