We like Foursevens flashlights. And while perusing their website to check out the new line of Preon flashlights, we stumbled across this: The Foursevens Navi. A small button-cell keychain flashlight, the Navi may not look overly special, but is the first in Fourseven's Smart Flashlight lineup.
That means it has a simple built-in Bluetooth interface that allows the owner to connect their smartphone to the Navi. When the Navi exceeds a certain distance from the phone, it can trigger an alarm on the phone, or even send an email to the owner's email address with the last location where the phone and Navi were last together.
And of course, we're sure it's an excellent little flashlight as well!
