TechBits: geocaching gear

Posted: Updated:

    This week, the Tech Guy looks at the electronics you can use for geocaching.  It comes after he got a big response to a segment on the hobby that uses GPS signals for a world-wide treasure hunt.

    People generally use GPS receivers or smart phones for geocaching.  GPS receivers designed specifically for geocaching are getting more common.  They can have lots of information loaded in- including much more than the coordinates.  They can store cache information, log book entries, rating information, and more.

    Smart phones can get all this information and more- and they can also update information on the fly- as well as allow web searches, and even more resources.

    So why would you use a GPS unit instead of a smart phone app?  Quite simply, accuracy.  When you're trying to find a cache based on co-ordinates, getting location information from a greater number of satellites can get you closer to the cache.  Also, some people just prefer using direction and distance information to trying to navigate using a map.  What you use should be based on your personal preference.
