It was a while that I was planning to get a serious GPS to accompany me in my metal detecting campains and I must say I am content of my decision on purchasing the Colorado 300.
The unit is rugged and waterproof, so you can handle it even with dirty hands, which I do have quite often, as you can imagine 🙂 It also comes with a carabiner clip accessory, which makes it extremely handy when your hands are full. Besides the usual stuff you can expect from a GPS, the unit comes with an integrated electronic compass, barometric altimeter and has a very accurate high-sensitivity receiver, so you can save your finds’ locations quite accurately. On my trips through the woods it only lost satellite signal once, in a very thick forest, but comparing it to my previous experiences with other GPS units, this one is better by far.
The only downside so far, is the slow text input system, which makes it quite painful to enter longer descriptions of your finds and/or locations. I managed to overcome this by simply accepting the default waypoint name and editing it later on my computer.
There are several options on the software side for waypoint and routes editing. If you are using a Mac, like I do, Garmin has a nifty application called Bobcat, which is still in beta, but I must say quite usable. For a full list of Mac apps made by Garmin, visit their Mac OS X site. On the Windows side, the range of apps is quite large, so you should have no problems locating any, still the most used is probably Garmin’s MapSource.
That’s about it folks, I would love to hear suggestions and comments, so feel free to post.
