SCIAM -- The rules of geocaching are very simple:
- Take something from the cache.
- Leave something in the cache.
- Write about it in the logbook.
Thanks to enhancements to the Wide Area Augmentation System, newer GPS receivers can determine a user's position within nine feet, assuming that the user has a clear view of the sky and that the weather is not too cloudy. I need to get a Magellan SporTrak Color, a unit on sale in several Dublin shops. It stores more than 100 waypoints, displays various features in different colours and feels good in your hand.
