Hello all,
I have a phantom 2, a H3-3D gimbal, and gopro 3 black.
I am looking to get a monitor that attached to my contoller because the iphone won't work with all that. Does anyone have any recomendations? Not looking to break the bank but also not looking to lose it in the wilderness. Also if anyone has anything on boosting the distance that would be great too.
Thanks everyone!

You'll need to investigate a VTx/VRx system plus monitor.
A place to start would be here:

And there are several ways to mount the monitor to your transmitter.
Secraft makes a neat tray...

DSLRpros.com has the best combo I have seen, It comes with a controller that doesn't suck and everthing you need. Mine will be here friday.
