Click 'n Dig Model E4 Key Finder. 4 Receivers. Wireless RF Remote Item, Wallet Locator

Why we love it?

All Receivers have flashing LED light as well. Click N Dig Products are FCC certified. 1 RF transmitter with 4 colored buttons. Extra Batteries and Thin Double Sided Adhesive Tape Included.

Some comments about this we saw on the web:

* /u/fabos on /r/BurningMan That sounds great, I think sound might be more effective than light though. In lots of places you’ll be in a sea of bikes that are all blinking with random patterns. If you have a remotely-activated chirping noise it might be more effective (unless you’re right by a sound camp).

…in fact I’m going to go look for something that does this. Thanks for the idea!
