Garmin GPS
Global Positioning System receiver, PC connection, and software

This probeware system is designed for the general public as a travel and navigation aid. The GPS works alone or can be connected to a computer to gather realtime data. It also can interface with street mapping software to display a "live" interactive location.

Equipment Information:

bulletSports Authority
bulletE&B/West Marine

Garmin GPS units are hand-held satellite signal receivers that display compass heading, latitude and longitude, time, distance and speed. The GPS unit displays such information constantly and accurately because it receives Global Positioning Satellite signals sending data needed for the calculations. The units have an LCD panel for display, and may be connected to a PC running GPS-compatible software. The GPS and the computer can exchange data and some GPS units can exchange maps.

GPS units begin at about $150, require a $40 cable, and software that may be downloaded or purchased.
