Introduction.
The Garmin Colorado 300
is the fisrt GPS to support paperless geocaching. In this review we’ll look at the Garmin Colorado 300
from a geocaching perspective and compare it to a Garmin GMAP 60CSx We’ve had both units on loan from Garmin UK for the past few months.
Whats in the Box.
So what do you get for your money, at the time of writing a Colorado 300 from Amazon is £265, with the GMAP 60CSx £210. The contents of the box for both units is roughly the same.

To get going all thats needed is to unpack the device, remove the the back cover, insert 2 AA batteries and away you go. Its at this point that the first difference between then units becomes apparent, removal of the back cover requires two totally different techniques, on the Colorado you have to prise open a stiff locking clip that holds the back cover in place, the GPSMap is somewhat simpler with a lift and twist ring common to the rest of the Garmin hand held range.
Battery Installation Instructions
Taken from the manuals of both units here are the instructions for installing the units batteries.

Design.
The Colorado moves away from the traditional Garmin user interface of a cursor keypad, and 8 function keys, all functions on the unit are now controlled using the Rock ‘n Roller™ input wheel designed to allow easy one handed operation.

From the images above the differences between the units are clear.
In physical size, theres not much difference between the units.
In Use, lets go caching.
Using the Colorado for paperless caching is an absolute pleasure. To make best use of the Colorado you need to be a premium member of the main geocaching listing site geocaching.com. Then simply create a pocket query for the area you wish to go caching in, download to an SD memory card, insert the card into the bottom of the Colorado 300, and off you go.
In the field we found the GPS reception to be matched to the GPSMAP60 both in accuracy, satellites seen, with the Colorado 300 aquiring it’s initial GPS fix slightly faster than the GPSMAP60. Both units proved to be a significant improvememnt on our current GPS60 Garmin unit, not surprising really given that developments in GPS technology.
The paperless caching capabilities of the Colorado give you access to the all the details on the cache listing page, including that all important hint. Along with several of the previous logs, these often prove invaluable in giving you some guidance on those more challenging geocaches.
The size, shape and weight of the unit mean that it sits nicely in the hand, making following of that all important arrow a pleasure, where the Colorado really wins over previous GPS units from Garmin is the introduction of the Rock ‘n Roller™ input wheel, using this input device located atop the Colorado’s clear LCD display you can easily use the same hand that you’re holding the unit in to navigate you way round the extensive menus and features of the Colorado 300 simply by rolling the wheel with an action similar to that used on a mouse wheel, or rocking the wheel in an action that can be best described as pushing a joystick. At first it does seem a little alien, but we soon got to grips with this new input device.

Perhaps the best example of the Rock ‘n Roller™ input wheel working to best effect can be shown on the map page, previously you would have used the cursor pad on the GPSMAP to move around the map, and the ‘in’ and ‘out’ buttons to zoom the map, using the ‘enter’ key to select or mark an item on the map. Now you simply rock the input wheel up, down, left and right to move around the map pretty much as before, roll the wheel to zoom in and out, and press the wheel to select, all whilst holding the unit with the same hand that your using to navigate around the map.
Memory Expansion.
Discussed above in the geocaching part of this review, both the Colorado and GPSMap can have additional maps, and waypoints added by way of an additional memory card, in addition the colorado can have geocaching information stored on the card. The location, and type of memory card differ between the two units.
With the Colorado, a standard full size memory card can be used, installation is under the battery cover, into a slot in the bottom of the unit, as illustrated below.

The GPSMap60 uses a microSD card located underneath the batteries. Again this is shown below.
GPSMap60 Memory Installation

One thing is clear, you certainly don’t want to be swapping the memory of the GPSMap60 when your out in a field, microSD cards are tiny, really tiny, they’re smaller than a mobile phone sim card, and anyone thats ever had to remove or re-insert on of those will agree it’s not the easiest task.
The colorado makes use of the larger full size SD card, which makes it easier to change in the a field, but not something we’d recommend doing unless you absolutely had to.

Conclusion.
Would we recommend the Colorado 300 ? Thats a most definitive yes, so much so with the unit from Garmin now returned, we’ve gone out and bought one to go geocaching with.
