Lowrance Expedition C Plus

[+CTC42]

I am new to geocaching but not new to maping and hiking. We are full time RV'ers and want a gps unit for: hiking with topo info, geocaching, and auto travel. We use Delorme Topo USA and Street Atlas 6 when traveling in our Motor Home. We have never owned a hand held gps unit. We would like color, a good resolution large bright screen, good reception, and good manufacturers support. I'd like to hear from folks that have used the Lorance Expedition (color with the topo maps) . Also those that have used the equivalent Garmin and Magellan. What are the pro's and cons, and what should I be looking for in models and specifications. I see the Lowrance Expedition with the topo maps and SD card at about $309. I think that is the Max price we are willing to spend. Thanks in advance for your posts.
