When it comes to enjoying geocaching, a GPS is not optional. As is often the case with necessities, a bad one can ruin your day while a stand out product can make the whole experience better. The Garmin Colorado 300 is intended to do exactly that when it comes to geocaching. Let’s see how it holds up.

First off, the issues with the previous unit seem mostly resolved. There certainly were issues. Almost to the point that it felt like the device and software were released too early. But now, that it’s fixed, it delivers everything that is supposed to.

The Benefits of Garmin Colorado 300 Geocaching Unit

I have to admit that there are a few new features that make the Garmin Colorado 300 geocaching better. For some I mean. From what I hear, not everyone is comfortable with the Rock ‘n Roller input wheel. It certainly took some time to get used to but just like anything else that’s new, you need some time to get the hang of it. Why would this be an exception? There is a learning curve, but you get used to it. Anyway, here are the highlights of the product.

  • The screen is big and clear. It measures 76 mm diagonally, and it comes with 240×400 pixels. The linework and text seem to be anti-aliased, which makes it more readable than before. Visibility is okay, despite the fact that the backlight is not too much, but not too less either. It gets brighter as you plug it in your car’s source of power.
  • The Rock ‘n Roller wheel. As I previously said, I don’t get why people get so upset. Yes, there is a learning curve, but you can get used to it fast. Just play with it for a few hours. Personally, I enjoy this. I can zoom in while on a map, I can access menus by scrolling up and down. It’s easier than using buttons. But that’s just me.
  • There is a new user’s interface. And it works perfectly with the input wheel. You can simply browse through the options using the wheel, and when you want to access a certain feature, press the center button. You can customize shortcuts to the features you use most. Text input comes up as a wheel as well. Rotate to get to the desired letter and push the center button to insert. You can also configure your GPS, manage tracks, waypoints, routes, and geocaches. You can even set and store the setting for different profiles. As far as I am concerned, this new user interface is way easier than the previous.
  • It features a built-in worldwide map, and the relief is shaded. I think that Garmin wanted to impress us with the so-called 3D maps of the Colorado 300, but honestly, my mind is split as to this is a benefit or a waste of time. It’s nice that there are the shadows, at some point you really do have the feeling of a 3D map, but when you zoom in, shadows keep emerging, and it can get annoying.
  • There is more geocaching support than previous Garmin models. Geocache data from their website can be sent directly to your unit by hitting “send to GPS.” button on the site, or you can import a PocketQuery file. The device will recognize the geocache information, and it will treat it depending on the waypoint. But from what I saw online, it seems that 2000 is the maximum of loaded geocaches. I didn’t test this myself, so I don’t know for sure.
  • Other things that I like are the highly sensitive receiver, the electronic compass, and the barometric altimeter, and the fact that the internal memory is 384 MB, but you also have a slot for an SD card.

Overall, I think that the Garmin Colorado 300 geocaching features are more than satisfactory. Its perfect for anyone starting out since you really don’t need much more than this to get the job done!

Garmin Colorado 300 geocaching drawbacks

Just as any other product, the Garmin Colorado 300 geocaching unit comes with a few disadvantages.

  • The search feature is close to useless. If you want to find a particular place, you can’t. You only have a “Find nearest” option. But if you want to go to another location, you have to scroll manually on the map. Although, it ‘s hard to find something when you don’t know where it is.
  • Map exploration is somewhat restricted. You are only allowed to zoom in or out at the found location.
  • I am going to mention the fact that zoomed in 3D maps of Colorado 300 are a failure. Too many shadows. They don’t go easy on the eyes and it can sometimes become very difficult to actually know what you’re looking at.
  • Controlling the map can be achieved mostly in the setup page. It would have been better if could do it on the map page menu. Almost all of the other products I tested had this option.
  • It has a slow startup, especially when you have many points. If you add more waypoints to the internal storage, they appear as processed only once, but if you add them to the SD card, it’s like they are processed every time you turn on the unit.
  • You can’t change the color of the track. I always like that on other devices.
  • If you save more than one track, you will be able to see just one at a time.


There you have it. While the device is a bit older at this point it is still worth the purchase. And considering you can pick one up on Amazon for a very reasonable price, I would say its certainly a good pick for your first GPS device. If you have a chance, take a look at the 3D map option and see if you prefer that over more standard options. I suspect that will be the main issue that people have.
