RE: anybody using GPS systems????
I like my DeLorme Earthmate PN-20 however the the newer PN-40 does come with a little more stuff. Both you can down load NOAA nautical maps for some of the bigger lakes. DeLorme has depth maps for most lakes so it probally will not be long before those are added to the collection. I just happen to like the Delormes better for my usage that's all..
