I'm doing some planning, and for the CDT, I've decided I want a GPS (short story = Evolution Basin, snowfield, whiteout, frozen lakes and ice bridges).
Having never owned or used one, I'm a bit lost (groan) when it comes to evaluating features (this is after spending time on various review sites).
Basically, I'd like these features:
1) Color screen where I can load and view 24K topo maps. Ideally, I'd be able to preload the majority of the trail onto a memory card.
2) Load trail breadcrumbs (a la Sly's sticky forum post)
3) The usual infinite battery life, zero weight, and cheap cost
As a starting point, I'm looking at the Garmin Dakota 20. Other than a smaller screen (it's 40% of the size of the Oregon/Colorado series), it seems the same as all the others.
Anyone have any evaluation tips? Is this screen big enough? I can head to the local REI to lay hands on a model once I learn a bit more.
