I am about 2 or 3 days away from purchasing a Pro-78 or an XTR-690. I really enjoy my 1793SE's compass, and have found it many times to be a time and headache saver navigating a new area. So, I am leaning towards the XTR-690 as it has a built-in compass too. I know a lot of people have voiced some level of concern that the XTR-690's screen is difficult to read in bright light. I just want to know, how bad is it? Unbearable? Okay? Decent but you're just really picky?
P.S. Yes I know I can just buy a stick-on compass for a few bucks, but I'd rather not. I am a simplistic person and don't like to be dangling too much crap from my windshield when a single unit can get the job done.
Also, can someone with the XTR-690 youtube the TEACH mode from the XTR-690? So far I've seen a lot of Pro-78 videos, including Roy's review, but none of the XTR-690 in action.
