I have the colorado 300. I dont use all the bells and whistles but I love it paperless is the way to go. Shows description, hint adn logs. Can't tell you how many times by reading the logs I got a smiley instead of a frown. You can add field notes, log as found,not found,and go to next closest cache. hook it up to your computer load caches , delete caches and access field notes. I think the Colorado 300 is very cache friendly. cw
