1) Built in PDA and GPS functions work together for an unbeatable geocaching experience.
2) It can store as many waypoints as you want 10,000+
3) It supports a 4 gig card! (You can put all of North America and more on there.)
1) Built in battery. (You can’t replace those batteries on the trail)
2) Non water proof and not as rugged as other models.
3) I keep losing the stylus.
