Step1
Buy a GPS unit, from $100 to $1000, depending on the type that you choose.
Check the Internet at Amazon and BestBuy, for example, and you
will find a whole range of possibilities. You may also check at boat supply stores as well as stores that sell camping supplies.
Step2
Place your cache, and enter the waypoint, or location of the cache, in the format of longitude and latitude for others to find. To do this, you use your GPS to indicate the position. The problem is that you can get different readings on different days, so you would want to take at least three readings—more if you have the time and inclination—on three different days, coming from three different directions. Once you get your three (or more) readings, average the latitude and longitude information to get as close to the actual location as possible. The closer you are to broadcasting the correct location, the more easily geocaching tourists will find what you stash away.
Step3
Know your particular demographic. This means being aware of the group of people most likely to buy your product, and, in this case, the type of people likely to be hiking, biking or otherwise making their way to your particular stash. What will they be looking for? What kinds of things would they need?
Step4
Decide on which product or teaser item might best be stashed. Only your
imagination can restrict you at this point. Suggestions include coupons,
gift certificates, small items of value with your company logo on them, booklets or brochures. Do not put food items in your cache, as some food will spoil while animals, with better noses than ours, may easily seek out and destroy such a cache. Respect local laws when placing caches, and do not stash anything illegal or harmful.
Step5
Choose a good waypoint. Don't make it too easy, as that would make it
vulnerable to anyone who might happen along. But don't make it too hard,
as you're looking for possible customers and clients, and you want them to be well-disposed to your product once they find your stash.
Step6
Promote it. Upload the location of the cache onto Geocaching. There, you can note the location, and describe your cache with as much detail as you like. In all, this is nothing new from the typical PR or marketing angle; this just gives you another area in which to promote your business! Take advantage of the surge in the popularity of geocaching.
