I know there have been threads on this forum about the 60CSx vs other models., but I have not seen this concern addressed. I have read that the 60CSx picks up satellites and holds them better than the CS. I thought the only difference between these 2 was the memory card capability on the CSx. I live in New England and I want a unit that will work under our thick summer foliage. Getting those Satellites is my main objective, not the extra memory. Is there an advantage to the CSx? Has anyone used both?
