Don't get me wrong, Clay. It *is* interesting, but not without disadvantages.
For the no-salt-water-body case, it takes a 'bucket'. lots of salt (mcGiver needed), some containment tube and still needs the pump and power to run it. It'll still have the variable length/breakup issue at the top of the water column. [mythbusters showed that stream breakup made peeing on the third rail (without getting electrocuted) 'possible']
Compare that with bringing some wire and monofilament line. IF there are no structures remaining to support wires, water equipment may be useful.
Now, using a salt-water filled hose, looks better and a garden hose or hospital tube would do. Better for a McGiver situation (as long as you carry the probe around . (;-)
I wonder about his turns ratio. Common I-Probes would provide a high impedance to the transmitter. I need to look up the secondary turns on mine to get the Z-Ratio.
