Henry,

I am not into Geocaching. However, your could Geocache with an aviation GPS
or you could navigate your airplane with a non-aviation GPS. It all depends
on what compromises you want to make between size, price, and aviation
functions.

Especially for VFR use, a non-aviation GPS makes a great tool. For all
practical purposes, you will have to load aviation waypoints as user
waypoints. Many receivers will hold 1000 points, some will hold 500 and
some will hole more. You can upload get these coordinates from a source
such as www.navaid.com and use a free program such as G7toWin to load them.

I personally prefer Garmin receivers. I especially like the ability to edit
the route directly on the map by essentially dragging and dropping the route
line. I also think the best navigation interface is the map display for
situational awareness and the data fields for precision. The Magellan units
only offer two data fields.

Some of the units that you might start looking with are the Garmin GPSMap76,
60C, 76C, 176, or 276.

Any pilot who's also into ground geocaching? I'm thinking about buying a
new
GPS receiver to use for that purpose, but also wonder if these hikers'
GPSes
can also be used for aviation, perhaps as a backup navigation instrument.
(I
use an older Trimble for flying.)
