Summary: A great GPS for a great price. I use a GPS in my work, for travel, and hunting. I really like the big touch screen, expanded memory compared to other models, and the improved sunlight readability. The electronic compass is very useful. Of course the SD card enables me to use many free Garmin compatible maps downloaded from the internet. The sensitive receiver works great for aquisition time and even in buildings.
Summary: I've been using this for geocaching for the last 6 months now, and once you've used this for geocaching (with a premium account), you won't use a non-paperless unit. The unit is remarkably easy to use, thanks to the touch screen. This is a good thing, because the manual is very lacking. The screen is dim, especially when compared to the other non-touchscreen units. The only time you want the backlight to be set to less than 100% is when you're using it at night.
Summary: As an avid photographer, I use this GPS for geotagging my images with location information after the shoot. The Oregon 300 allows me to do this easily. I simply synchronize my camera's clock with my GPS's clock, create a new tracklog which updates at 1 second intervals, and start photographing.
Summary: HARDWARE Oregon series feels sturdy yet light. It is a beautiful device from a hardware standpoint. SOFTWARE We expect a modern GPS to do more than provide GPS or UTM coordinates. In 2010, there is a high expectation of convenient map management. Unfortunately, despite years of user criticism on numerous websites, the company still fails to improve its portfolio of applications to install (MapInstall and MapManager), navigate topographic maps (BaseCamp), route planning...
Summary: I have owned this device, my first gps unit, for 3 months. It is a rock-solid device and has a very nice feel to it, a sort of tacky-rubberized band around the outside edge , which keeps the unit from slipping around in your hand. It has a crazy number of features and abilities, most of which I will never use. I bought it for off-trail hiking and it works very well for this purpose.
