If there ever was two things that go great together, it is peanut butter and chocolate. If ever there were two things that go great together, it would be the aforementioned peanut butter and chocolate and then GPS and cell connection. The pair are a regular Batman and Robin of the gadget world. Now, they want to save your watercraft.

Maybe you remember this dude? He owned a motorcycle that apparently, everyone wanted and it kept getting stolen. So, the dude went out and purchased a GPS snitch so the next time it was stolen, the cops tracked it down. And then the next time it was stolen yet again, the cops tracked it down. All thanks to GPS and a cell connection.

Check out the Harpoon, a GPS device that does a bunch of tricks to keep your boat safe.

Twice thieves have stolen this guy’s motorbike on the tough streets of New York. Twice, this guy has led police to his bike to recover it. Smooth. It makes the $300 investment in GPS Snitch and the $14.99 per month charges seem pretty small.

The GPS Snitch works with both GPS and cell tower tech to deliver text messages alerting you to movement beyond a perimeter you set up. The GPS data can be viewed online or even via a cool BlackBerry blip application that guides you to your property. The tracking updates every 5 seconds or so and can port the data to Google Earth.
