Summary: I was skeptical about the Dakota 10 by Garmin because it lacked the SD card port and also lack of compass, but I found that the memory was more then sufficient. I've loaded (being piggish) the entire West Coast topo maps + marine Maps + Navigator city in this unit and no problems. Also my 4 year old managed to get her hands on it and dropped it in the dishwasher when her mom was not looking - and it worked fine after a full wash cycle, very impressive for the little...
Summary: I like the paperless caching. Accuracy is not as good as the 60Cx but is much better than the E-Trex. The maps (which cost extra) are not as good as the Delorme PN 30 (which comes with it), but the battery life is much better.
Summary: I at first hesitated to buy this GPS unit. I was one of the first people to buy a Colorado when they came out and I was so disappointed with that unit for Geocaching that I sent it back and lost $50 on restock. So when I saw this unit come out I was not sold. When the GPS came in I took it along side my trusty GPSmap 60CSX to the mountains of Western North Carolina. I fired up both units before we left on a 6 mile 1700 elevation hike.
Summary: The map this unit comes with is VERY basic! It has only major highways. So right out of the box this unit is useless for any type of navigation, especially outdoors. Garmin wants you to buy maps from them! Even though you can find them and download some for free, you have to buy software like Mapsource to install those maps! Now why would you pay this much money for a device that is completely useless out of the box???
Summary: Very small viewing screen that often did not respond to the touch. The display of Latitude and Longitude is smaller than useful in field biology work. I'm not interested in continuing the use of this GPS.
Summary: I'd heard great reviews about the Dakota; my one concern was whether the "10" version - which doesn't offer SD card expansion - would have enough memory. It's proved to have plenty enough memory for my purposes, including storing topo maps for three states and several dozen geocache descriptions.
Summary: I recently decided to start spending some time geocaching with my son. I finally settled on either the Geomate, Jr., the Garmin Dakota, Garmin Oregon or DeLorme PN-40. I asked questions at forums, looked at on-line reviews, checked out the ones I could find in stores (Oregon and PN-20) and finally decided on either the Dakota 10 (a great price on a bundle was the big attraction at the time) or the Oregon 300.
