Here’s s0me quick picys I t00k.
Pretty basic, as the eTrex series is supp0sed t0 be, but this is the better m0del 0f the 3 new eTrex m0dels, the 10, 20, and 30. I w0uld pr0bably rec0mmend the eTrex 10 n0w as the basic unit needed f0r IPX Treks. h0wever really thats just because 0f the price, y0u wanna g0 with a 20 0r a 30.
