About the screen visibility: can't say if they've improved or not as I have only seen this one unit. If the sunlight is direct visibility is super. If you were using this on foot you'd have unlimited options for orienting towards the sun and it'd be great I'd think.
Yep, on foot all the touchscreen models are great units. On the handlebars, not as much...
I had an older Oregon and found it unusable on the bars. My Dakota is a step better, but is still not readable enough for me to use on a bikepacking race. FWIW, the Dakota is supposed to be a touch more readable than the Oregon 550. I don't know since I haven't tried a 550.
...in any case, the 500 pt/20 track limit applies to the vista hcx but the Oregon is different - something like 10,000 pts per track and 100 track capability. I could be off on that - Scott care to chime in? I know for the Coconino route I had to split it into 2 pieces. 250 miles of high res data was just a touch too big
I believe that is correct. 10k tracks and 100 or maybe 200 saved tracks. This site is a great resource for the Oregon:
