Comments about Garmin eTrex 20 Topo GPS Bundle:
Why the eTrex 20? I began with the notion that I wanted a handheld that I could use with Topos, but also on the water. This meant to me that I wanted to be able to have SD card as an option. I considered the GPSMAP 62 series first, then the Colorado 450T and finally I decided that for the money, the eTrex 20 did everything I wanted at a price much less that the others and did not have a number of reviews about how hard it was to read the screen in bright sunlight, etc.
So, having decided on a unit, why the bundle?
I needed the cable, to upload 24K topos, the case provides protection from scratches to the screen, the 100K topo shows roads other than major state routes (unlike the built-in map) and for trips in the car, shows all of US. The belt clip may or may not be a plus.
I plan to use the 24K topos for travel in the Olympic Nat'l Park/Forest. These are on a disk while the 100K Topos are on a micro SD card. The maps from the disk are easily selected and loaded onto the unit using the BaseCamp program, free from Garmin. The 100K map is downloaded from the unit to a computer using the same program. So the deal on maps and units ( as I understand it) is: if you download the map/chart, it gets tied to a single GPS unit. If you have the chart/map on a SD card, you can move it between units but in order to display the map on the computer screen, the GPS unit must be connected to the computer. Since maps/charts that come on a disk are already on the computer before they get to the unit, this connected requirement goes away.
Things I learned in the process of getting used to the unit: 1) more than once I got confused because I forgot that there may be many more menu items available than are visible on the unit screen. ( well, duh is appropriate here).
2) My house is at an elevation of approximately 12 ft but one morning the GPS booted up with a first
fix showing an elevation of 395 ft and it took the better part of 30 minutes before this initial fix was diluted away. Positional error was also great initially ( the whole road was 500 ft off to the left, e.g. I attribute the lousy initial fix to an unfortunate constellation of satelites and the long period of correction to "pinning" which is usually a good thing but on the odd moment can make it a pain to get back to better fixes.
3) The initial download of the 100K Topo map from the unit took ca. an hour. Why the download seems much longer than uploads is beyond me but it was so slow that I did not notice that the good people at Garmin put a blue line by the download label which is supposed to show you about the progree of the process. You have to be patient in this day of gigabyte transfers before the blue line changes enough to know something is happening. Just my poor expectations. There are many thing I lkie about this combination of maps and hardware, it works for me.

Quality piece of equipment. Fast to set up. Easy to use. And, it's really lightweight and easy to put in a pocket or pack. I use it hiking and marking waypoints.
