The Goat

I had different ideas of what futuristic tracking chips would look like back in the 1980s. They lacked these big antennas and battery boxes that come on the Garmin Astro DC 30 GPS—this thing looks more like an FM radio headset from the aforementioned decade. The Astro is used to hunt your untrained dog in the style of The Most Dangerous Game remake that starred Ice Cube; I think Gary Busey was in it, too (what was that movie called?). You just plug your animal into the thing and then follow it around on your four-wheeler for the next 30 hours of battery life. It sends a signal to your handheld GPS from 7 miles out, and it costs about $200.
