Well, a rifle for fishing? I'd rather use a shotgun seeing it will go deeper.
I just started geocaching (this weekend actually) and used my NUVI 360. It's not perfect, but for those short jaunts, it did the trick. Fragile? Yes. Did it get the job done? Yes. Would i trust it for a long hike? No.
I am currently looking at other options. I like the touch screen, but it will stay in my Jeep. the 60CSX is expensive, and while i may do that, i want something i can drop and not have my heart sink when it does.
