Sounds like the contours are good. A couple of us use midland xtc280. We like them. Out of us 2 I have been having record time issues, but I just sent it in under warranty for that problem. We'll see what the outcome of that is. 3 year warranty so that's cool. Austin's camera works great every time. Records all day. I have several trail riding vids on youtube. You can see how some of the individual segments are continued in next segment. The camera automatically cuts each recording session into 10 min. Segments. Here is a link to my vids.
