Recording GPS and Photo Data


Hand held GPS locating devices are inexpensive, easy to operate and accurate to within several yards of where you stand. Your next-generation explorers will be able to return to the exact coordinates of each capsule at any time in the future.

Which GPS device should I buy? For starters you’ll want a hand held GPS designed for hikers, not EXploristhighway drivers. Retail prices have come down over the last few years and range from about $100 to $250. Even a Smartphone or used GPS is a good alternative. You need a waterproof device with a long battery life and a built-in map screen. That display screen should be as large as you can find. You want a 12 channel parallel receiver, which gives you more incoming signals to help guide you through forest canopies or around steep hillsides. Two additional recommended options are 1) the ability to upload different topographic maps and 2) a trans-reflective color screen for viewing the GPS in full sunlight.

Any of the following GPS receivers are appropriate for this adventure.


 eXplorist series
   60 (including CX models)
76C (including CX models)
Vista and Vista Color models
Legend and Legend Color (including CX models)
Venture CX

Don’t Forget Your Camera! For added security, you must take photographs and create prints to slip into your Retrieval Folders. To identify permanent landmarks, shoot wide angle images from multiple positions around your drop site. Never trust that you have taken enough documentary photos. All of the good directional photographs will be appreciated at the time of future retrieval.
