@tarstarkas, color options are something we've been going back and forth on. An easy way of gauging interest in different color options may be a survey closer to production to see what community interest is in these options. If for some reason it proves to be difficult to provide various colors (there's not enough demand), it would be incredibly simple to give the drone a custom paint job as well (in white, it's practically a blank canvas). But I agree, I wouldn't want you losing your drone because of its color! Regarding your other questions, it may be possible to integrate a "Return to Surface" safety feature! Although we don't have it integrated currently, it's on our to-do list. And yes, you will be able to take save videos from your drone and download them onto your iPhone using our "Divelog" feature in the application! I hope that helps!
Certainly an idea but, personally I don't think it's necessary as one could affix various high visibility stickers (or paint) to the drone. I think white would be the most visible color to find it under water. At least in my local waters it would be.
Good point @mikeli! I didn't even think about decals!
