Hi!
I'm considering to get a CrystalSky for use with my Mavic 2 Pro. I'm currently flying with an old Nexus 5X or an iPad 9.7" depending on what I feel like for the day.
Now winter is coming and smartphones and iPads struggle a bit with the cold, and in the summer the iPad tends to overheat.
1. My first concern is if the CrystalSky uses PWM for backlight control, thus having a flickering backlight? I get severe eye-strain and migraines from flickering backlights, even if the flicker is fast enough not to be visible. That's a showstopper for me. Does the CrystalSky use PWM? One way of testing is to point a video recording device (phone or camera) with manual shutter speed settings at the screen at different brightness levels (20, 50 and 100% for example) and adjust the shutter speed back and forth while looking for lines to appear in the camera view.
2. I have to also consider the Smart Controller as an option. I need something that holds up to temperatures below freezing, and the summer sun while being dependable for professional use. The biggest benefit of the CrystalSky over the Smart Controller is screen size. 7.85" vs 5.5". I really enjoy the size of the iPad over my 5.2" phone. Much easier to see details. How do they compare otherwise for professional use and getting the job done? Same question about the Smart Controller as above. Does it have PWM flicker?
3. iPad is still an option. I haven't used mine to fly in below freezing temperatures yet. Does it work well? I didn't like how hot it got in the summer, so if I'm using an iPad to fly I'll get last years base model specifically for the drone and not put excessive wear on my shiny expensive one. If it's not reliable in the winter it's however not a viable option.
Any other thoughts?
Grateful for any help
