Remote Finder

I know Brookstone has a detector key, but goes on a keychain, but I'm looking for something that can go on a remote control. If I find anything I'll end up getting the Finder key, but I was wondering if there are other options for me.

You can use the chain or you can use some Valcro. Caution, however, the batteries of these researchers go very fast. Most people stop using them after changing the battery 2-3 times.
