Wireless blockage monitoring for airdrills

[SRFarms]

Does anybody out there have or even heard of
the wireless blockage monitoring for air drills? I
stumbled across it tonight on my iPad and it looks
pretty cutting edge. If someone uses it already, or
is going to buy one, what's your opinion on the
product? I'm up for just about anything, this
concept is completely different than any of the
other blockage monitor systems out there that I
know of. The company is called Intelligent
Agriculture Solutions. Thanks

Saw them at the red deer farm show they looked
pretty good. You just half to calibrate the sound
levels when all your runs are good and they let
you know if sound levels stop.
