Do I Need Topo Maps?

[+gravesfamily]

I was looking at the eXplorist 210, the eXplorist 210 outdoor bundle, and then the Garmin eTrex Legend Cx.

 

The question that came up in comparing things was whether I really need the "MapSend Topo 3D USA" software the comes in the outdoor bundle. If I do NEED it, then that's an additional cost for the Garmin unit that puts it out of my price range. If I don't NEED it, then it's just a nice added bonus when buying the outdoor bundle versus the pieces individually.

 

I guess the reason I have to ask is because I don't understand the difference between what is in the "base map" included in the unit versus what the Topo maps would add on?

 

If I'm just using it for geocaching and not hard core hiking or even auto routing (I have a gps in my car already) does that effect the answer to my NEED?

 

Thanks!

If it's just for geocaching, then save the money and don't bother with Topo maps. They won't help you find a cache one bit easier. Now...If you're just interested in seeing the terrain in a particular area, then the Topos are great. That is what they are for...Reading the terrain. A basemap will only show freeways, business establishments right near freeway exits, RR tracks, highways, major secondaries and large physical objects, like lakes, rivers and the such. (Basemaps vary with the manufacturer and the model)
