Garmin has produced some great handheld GPS
receivers over the last few years including the 60csx
which we depend on during our on the job back
country trips. This unit basically works to provide
accuracy and repeatability 90 percent of the time.  
Recently two new models have been released to
replace or improve on the 60csx.

The first model is called the Colorado and at a
distance its profile looks similar to that of the
venerable 60. However up close you will find that its
display screen is much larger and it does not have
any physical keys for data input. At the top of the
unit is a large wheel similar to that found on some
portable music players that are so popular.  The
larger 3 inch TIFT screen is an improvement
however it is not as easy to view in full sunlight as
older Garmin models. If you are into Geocahing then
this unit will make playing the game a lot easier
since you can download data directly making the
exercise essentially paperless.

The Garmin Oregon is the newest of the handheld
mapping GPS models to enter the market.  Like the
Colorado it has the larger 3 inch screen which
makes viewing map details much easier. The
physical texture of the screen is not as shiny as the
Colorado which reduces the amount of reflection
during daylight operations. However daylight
viewing in full sunlight is also poor even with full
backlighting.  The largest difference comes from the
fact that both the antennae and wheel are missing
from this unit. The Oregon’s inputs with exception of
3 buttons including the power on are done via touch
screen. This is a great improvement in terms of ease
of use but also reduces the size of the receiver.  
Again this new unit has many features specifically
designed for Geocaching.

You have the option of purchasing both units in a
low cost base form (model 300) that will give you a
lot of great features. However you also have the
option of purchasing the 400 series models that
feature  enhanced mapping features that include
coastal and inland nautical maps covering most of
the US and Bahamas. The "C” model includes
charts that cover coastal waters and the Great
Lakes and the" I" model has detailed navigation
charts for inland lakes. In addition the model 400t
has preloaded topographic maps of the entire US
with the ability to use SD cards to add detailed maps
of some National Parks and Forests.  Both models
allow you to install MapSource cards that will give
you turn by turn street navigation capability.

In terms of performance we found that both the
Colorado and Oregon worked very well. However
they did not appear to be as accurate as some of the
older Garmin models such as the 76s and 60sx. The
two new units seem to have more track drift than the
older units. Satellite acquisition was much slower
than expected but that may be because amount of
mapping software installed in each unit.

Both the Oregon and Colorado have a lot of great
features but one feature that we really would like to
see is ability to clearly view the display in full
sunlight without using excessive power drain of
backlighting. When you are in the bush battery
management is a priority and neither unit is very
efficient. An increase in battery life would be greatly
appreciated.

At this time we will hold off purchasing any
additional Colorado or Oregon GPS units until
further improvements are made. We will continue to
monitor all the software and hardware
improvements as become available.
