From the photo on the RigExpert web site the StickProX display looks to be the same as the StickPro. The specs state it's a TFT as is the StickPro.
There are 5 different screens that you can select on the StickPro, Lime Green, Yellow, White/Light Blue, White/Red, and White/Orange.
The ProX photo appears to be the White/Blue screen with works extremely well in sunlight.
I have a StickPro as well as an AA-230 Zoom. I use the StickPro for field use.
