Default Additional Knock Sensors?

Last night I was checking out my friends Kenne-Bell supercharged Jeep. And he had a knock sensor gauge, as well as 2 additional external knock sensors. You could tap the sensors and hear the motor retard the timing.

I thought this was very cool. I'm just curious why something like this couldn't be done on the c5's? I know we have the original 2 from the factory, are they really good enough?

I mean i think a gauge would be helpful, at the least.

What's your thoughts?

There's good stuff out there, like this which I use on my boat.
I don't think this is available in an 8 coil version though.

One of the challenges is detecting knock while not picking up other noise and getting a false alert.

I'm not even so worried about the retarding of the timing, I'd just be curious if a gauge was possible. It'd be nice to know if i should get off of it for one reason or another.

There are gauges that will read PCM via ODBII and display .KR or knock retard.
