The main "Navigator Pucks," I use these (yes, I have two.) to keep the mapping software (Street Atlas USA, which the LT-20's were bundled) active. The design inside is similar to the GPSr antenna of the Garmin eTrex line. (a small board with the antenna & electronics, separate from the display board.) Both, Spike & Ducky (yes, they do have names) have actually found a single cache each. (leaving them with the laptop computer in the car, and going by the obvious landmarks.)
