"This is a fast unit with quick satellite acquisition."4.0 starson by nordwonder
Pros: Speed, quick acquisition, rapid screen redraws. Even at highway speeds with large scales, there is no lag. Huge map library and aerial photo support. Included Topo USA software is a real plus.
Cons: Slow transfer over USB, but Delorme recommends transferring directly to the SD card, anyway. That's as fast as any other data transfer.
Summary: I love this unit. Topo USA software is great.
