Industry standard for camera monitors is SmallHD. Nothing comes close to the usability of their Page-OS platform, and I'm guessing this Nauticam housing is using a Feelworld monitor, or something equivalent. Those monitors are fine for the price point, but the UI is clunky and lacks certain pro features. I'd rather pay a little bit more to house a 503 Ultrabright, which I could easily remove and use as a regular monitor.
