Electronic gurus, I need your help
 

I am organizing a game (terminator wars) where some devices need to be found. I would like to put a low power transmitter in each of those devices and have some kind of detector beeping when it get close to a transmitter (the closer the faster the beep) or something similar.

My fallback is to use a key finder devices, but with these it is the emitters that beeps which is not optimal for my game.

Any suggestions?


Thanks

Boom!

Maybe a bit on the expensive side though, but you've got everything you need

Also, for you guys with tornados, stick these to them! I know I'll do when/if I buy a few of these nades

OMG this is freaking awesome!! But damn I already spent more thna 2000$ for that game, I can't buy this :-(

Oh fuck that, this is way too cool, I am buying it!!

Wow, good to know for the everyday life. I can see a lot of places where this is useful!

Or if you want actual location (rather than hot & cold) you could use a chirp.

Of course, you would need handful of compatible Garmin GPS units as well...

Glad I could help Broken!

There is so many places this will be useful. Thanks again.
