You have a smoke detector. Depending on where you live, you might have a radon or a carbon monoxide detector in your house, too. What do these threats have in common? They may not occur frequently, but when they do, you need to know immediately, because they all have the ability to do you some pretty severe harm.

And that’s why we here at ThinkGeek World Domination HQ created our deluxe Jurassic World Dinosaur Detection System. It ships with two of the three elements vital to the complicated detection system – you provide the detection medium. Use our patent-pending dinosaur detection system to distinguish between four different threat levels:

Ripple Level 1: Area secure
Ripple Level 2: Possible dinosaur
Ripple Level 3: Dinosaur approaching!
Ripple Level 4: Run! Attack imminent!

Note: ThinkGeek cannot be held responsible for your safety if you wait until Ripple Level 4 to evacuate the area.
