Ever have one of those "GPS days" when the darn thing is providing a bearing that looks way off the mark...."that can't be right?"
I have a few recommendations to help improve the inaccuracy that the hiker is experiencing.
First, calibrate the electronic compass. Always calibrate the compass after installing new batteries. (Check the owner's manual to determine if your GPS has an electronic compass.)
Second, turn off the GPS, turn it back on, select "find" and evaluate the new data to return to camp. Check the satellite view screen to ensure that at least four satellites are being tracked. Consider moving to an area that has an open view of the sky.
Third, if the information present still looks in error, take five to ten steps in the direction recommended to see if movement effects the data displayed.
Fourth, open the battery compartment and remove one of the batteries. Keep the battery out for 10-20 seconds and then return it to the GPS. Power the GPS back on and repeat the process by selecting "find" to return to camp.
Lastly, it may be that the saved position of camp was made before a solid satellite lock was achieved. Compare the saved coordinates for camp with the plotted position of camp.
Usually, these five steps will clear up the issue.
Remember, never leave your map and compass at home.
