Garmin Gps Etrex 20

Will a Garmin Etrex Legend allow me to track a route?

I am an avid fisherman and fixing to buy a handheld GPS system to take along. I am 99% set on the Garmin Etrex Legends, but have one question. I often travel to a fishing hole before dark, sometimes 15-20 Miles. When leaving and heading back to dock, it is dark and often visibility is bad. Will this GPS allow me to track an exact route that I took to get to the location and reverse it to return home. I travel the river channel to miss obstacles, and at dark it is hard to do.

Any of the etrex family will allow it.

I am assuming that you are considering one of the newer models, either the H or the HCx. The old one without any letters behind the name is not as good.

The H indicates the newer high sensitivity receiver for more accurate readings of your location.
Both will allow you to load maps if you want to get lake maps. The x model has basicaly unlimited map space since it can use a 2 gig memory card for the maps. With the H model and with WAAS (a system for correcting for atmospheric issues) turned on, you can expect 10-20 foot accuracy in the US, which is about as good as any unit priced for home use can do. There are engineering units ($$$$$) that can, with the subscription to DGPS transmitter (more local corrections than WAAS), get you to well within an inch of your location. I have been in a car used to create road maps and we mapped the edges of a drivers training track to within 1 cm GPS accuracy (the driving probably was not that accurate).

If you use certain lakes frequently, you can use the Mapsource program that comes with the unit to create (with data from a couple trips) a better map for the routes and add waypoints for particularly bad items or good fishing spots that you are willing to let friends know about.

I agree with the other poster that some sort of light is also a good idea. With WAAS enabled you can expect to have a 10-20 foot accuracy on the location (better the farther south you are in the US but I got very good readings in Canada). Depending on the channels in your lake and the speeds you go, you may need a light to watch for rocks or logs. A standard headlight is a narrow beam that shows you things farther ahead. A fog light would be good for areas where you need to turn more often but at lower speeds.
