5. AMOD GPS Tracking Unit
The AMOD AGL3080 is a GPS-based data logger designed to provide location information for digital photos (in EXIF 2.0 or later format) from all digital cameras and camera phones. Additionally just having this thing in your pocket while you ride means you are being tracked by earth-orbiting satellites. Plug it into your computer when you get home and you can view/ print a map of where you’ve been.
USB port enable charging means popping rechargeable batteries into the receiver allows for recharging each time you insert the unit into your computer.
