Step 1
First off is choosing between a mapping screen vis-a-vis a numerical longitude/latitude readout saying where you are. Many reviews say this is one area to insist on value for money. The function enables you to see where you are from a reference-waypoint point of view.

Step 2
Get a waterproof or water-resistant model as much as possible. For water-resistance ratings, look up the IPX standard of the device. Am IPX of 4 means the device can withstand water splashed on it. However, for a GPS that can withstand accidental swims in the pond, you need a certified IPX-7 model.

Step 3
With regard to the memory size of routes, go for the standard of a twenty-route memory. But you can go for as many as 50. For the still route-memory hungry, there are the GPS receivers with memory-card slots.
-
Step 4
Units with 500 user-entered waypoints are safe choices.

Step 5
Of course, you also need to address size and weight issues. This is where you, yet again, take stock of your personal preferences and lifestyle. There is basically a direct relationship between weight and screen size; so will it be a bigger display (which means a bigger unit), or the other way around?

Step 6
Pick the unit that employs a 12-channel parallel receiver system. The advantage in this is that you get the best signal even in wooded areas. The latest currently have 15 channels.
