If you follow any of the Gear Diary editors on Twitter, you know that during CES 2010 we were constantly tweeting our location. One day during the show, after tweeting that I was near the South Hall, I received an @ reply from one of the vendors on display there. Phone Halo asked that I swing by their booth for a demo. So I did.

What is Phone Halo? Phone Halo is a new product, that’s available for pre-order, which helps you safeguard some of your most valuable possessions, like your keys, your cell phone and your wallet. If you’re constantly losing things, then this might be the device you need to get back on track.

Designed to fit on your keychain and meant for small wireless devices, the Phone Halo communicates over Bluetooth with your cell phone keeping track of your location. If the two devices become separated the Phone Halo alerts the user with an audio or a vibration tone on both devices.

Each Phone Halo uses software which gets installed on the user’s wireless device and helps manage settings including enabling GPS and e-mail notifications. Additionally you can use the software running on your phone to track the location of your Halo. So if you’ve got it attached to your keys and you lost them they will be easy to track down. The GPS function of the device plots where the phone and the haloed item became disconnected marking it on a map.

The Halo’s built-in rechargeable battery lasts for approximately 2 weeks with a single charge.
