It's called a harmonic reflector.

Say radar works at a frequency of 1 GHz. RECCO uses a small electronic circuit to generate a harmonic (integer multiple of that signal) which goes back to the sender.

Signal out at 1 GHz

Returns at say, 2 GHz.

Basically just like the chips they put into items you buy at a store, and when you walk out and you haven' t payed for them alarm goes of.

This.. You're lucky if you're located and saved by recco technology when you're buried..

so you are the asshole that will kill someone because you value a gopro over a life. while they are frantically trying to locate a buried human, they will accidentally be following the signal from your lost cellphone.


bad, bad idea.

A recco is used when the person is presumed dead and their beacon batteries have died. Otherwise they use a beacon to.locate the person because a beacon is not nearly bulky as a recco locator.

i thought it was a pretty good explanation of why they sometimes use reccos and sometimes use beacons.

a cell phone signal will not interfere with a recco locator. the reason it detects these electronic devices is because the batteries in them are mostly metal, and reflect the signal.
