Suspecting a spouse of cheating is unsettling. Catching a spouse in the act by using GPS is an idea many of us wish we had thought of earlier. Make sure that you can prove your spouse's whereabouts before you accuse him of cheating on you. The use of a GPS, or "global positioning system," is one of the easiest ways to know if your spouse is somewhere he shouldn't be.
Decide on a portable GPS model. There are many to choose from, so make sure that you purchase the one that's right for your situation. They range in price from approximately £64 up to hundreds of dollars each. The Spark Nano is small enough to fit in a glove compartment. The Car Camera Pro has a voice recorder and tracking device using Google Earth. For larger budgets and very small spaces, WorldTrack is fully self-contained and small enough to fit in the palm of your hand.
Place the portable GPS unit in your spouse's car. The portable ones are small enough to be placed inside a cigarette lighter, behind the VIN number plate, or under the passenger seat. Pick a place that you'll remember and your spouse will not look.
Turn on the GPS unit remotely from your computer. Log onto the website of the specific model and enter your chosen code. This will start your portable GPS and allow it to track the car's specific location at any given point. Make sure you register your GPS so that it will give you the correct information for your unit.
Type in the tracking number the company gives you. This will begin the process of remotely tracking your spouse's car every time it moves. It will be recorded into a file that you can retrieve from any computer as long as you have the pass code information.
Be sure to check out the locations the GPS gives you. You don't want to jump to conclusions and assume your spouse is cheating when in reality he's only gone to the bank. To be on the safe side, make sure your spouse goes to this same location a few times before you question him. He could be dropping off a co-worker or something just as innocent.
