A GPS receiver, for our purposes, is a small hand-held
electronic device that receives multiple satellite signals to
determine its position pratically anywhere on the globe. Further
detail The accuracy of GPS receivers varies depending on a
number of factors, including time of day, weather, obstructions
(trees, buildings, etc.), satellite geometry, WAAS signals, and
more. Many geocachers allow their GPSr to get them close to a
target, and then use The Force to guide them the rest of the
way. Units prices can range from a under $100 to more than $500.
Selecting a GPS for Geocaching The bare essentials for a GPS
unit (GPSr) used to hunt a geocache are: (1)the ability to input
and display user coordinates to three decimal places for the
minutes, and (2)the use of WGS-84 (NAD-83) datum. While some
have successfully hunted caches with units that don't meet these
minimums, they do have some difficulties. All consumer grade
units sold in the last few years will meet these minimums. Can't
