Most of the current consumer brands of GPS units use a state of the art GPS receiver. Most of these are the size of your thumb nail and will produce an accuracy within 3 meters when used with the WAAS correction differential.
There are many units that may satisfy your needs, so do your homework and check out the price vs your needs.
The difference comes how large the screen is, if it in color and how the company writes the operating software to access the various GPS data that the unit receives. Many units only have two or three different screens with a very limited of features on each screen. In addition, what many users believe is the MOST crucial ingredient, what mapping and other accessories are offered for the unit.
A very expensive unit that has only a very limited type of mapping that does not cover the area you will be using unit would not my first choice. Many users are buying their units by the type of mapping that is available for the unit. Most of these mapping programs are sold as an accessory. I believe this is to diminish the sticker shock price of the units.
A supplemental mapping program is almost a necessary item as most GPS units only come with a Base Map. This is just what it implies, a basic map in order for you to use the unit. It is usually lacking the detail that their supplemental maps have.
So, go to the manufacture’s web site and narrow down your choices for each brand. Access the on line owners manual and note the screens internal options, the amount of waypoints, tracks and routes the unit can store, and if it can accept downloads of data and maps. Then go to a stocking dealer and view the actual unit. Go to an area that you are familiar with and zoom in to that area. Note the detail of the available mapping to discern if it meets your needs. If it does not, try to see some of the accessory mapping for the unit.
Do your homework and investigation and select your unit from your results.
