I have just recently become aware of geocaching and could not wait to try it out. Needed to get a GPS'r and I used a gift certifcate from Amazon to purchase the magellan explorist 100 for about $100. Although I have nothing else to compare it to, this unit seems to suffice quite well. I was in extreme tree cover on one occasion and it did not go offline. The accuracy in distance and mph when travelling in our cachemobile is uncanny, I could not believe it! The backlight does work extremely well in the dark, offering two levels of intensity which make the screen easy to view. Hope that helps and I hope I am posting this correctly..........my first time at this as well! Good Luck!
