Touch and Go
Oregon 650 has reflective display technology for the most brilliant, sunlight readable touchscreen we’ve ever made. It's as vivid in full bright sunlight as it is in shade. The screen has been strengthened for impact resistance but still accommodates gloved operation. And with dual-orientation, multi-touch screen, you won’t just look at maps, you’ll interact with them when you zoom in, pan out and rotate the display.
